batched_input (list(dict)): A list over input images, each a
dictionary with the following keys. A prompt key can be
excluded if it is not present.
'image': The image as a torch tensor in 3xHxW format,
already transformed for input to the model.
'original_size': (tuple(int, int)) The original size of
the image before transformation, as (H, W).
'point_coords': (torch.Tensor) Batched point prompts for

'masks': (torch.Tensor) Batched binary mask predictions,
with shape BxCxHxW, where B is the number of input prompts,
C is determined by multimask_output, and (H, W) is the
original size of the image.
'iou_predictions': (torch.Tensor) The model's predictions

cross_attention (bool): If True, expect to get secondary input for cross-attention.
layer_scale (float, optional): If not None, LayerScale will be used

xpos (bool): Apply xpos exponential decay to positional embedding (rope only).
lr (float, optional): learning rate override through the `make_optim_group` API.
weight_decay (float, optional): Weight_decay override through the `make_optim_group` API.
layer_class: (subclass of `StreamingTransformerLayer): class to use

"""Abstraction around providing pattern for interleaving codebooks.
The CodebooksPatternProvider abstraction allows to implement various strategies to
define interleaving pattern of sequences composed of multiple codebooks. For a given
number of codebooks `n_q`, the pattern provider can generate a specified pattern
corresponding to a sequence of `T` timesteps with `n_q` parallel codebooks. This pattern
can be used to construct a new sequence from the original codes respecting the specified
pattern. The pattern is defined as a list of list of code coordinates, code coordinate
being a tuple with the original timestep and codebook to build the new sequence.
Note that all patterns must start with an empty list that is then used to insert a first
sequence step of special tokens in the newly generated sequence.

that should be true for efficiency reason to avoid synchronization points.

3. Present the updated priorities in a JSON format, each item should be represented as a key-value pair, where the key is the item name and the value is its priority on the scale from 1-3. An example output is: {{"Fixture Y": 3, "Module B": 2, "Product G": 2}}. The descriptions of the priority scale of items are as follows.
* 1 - This item is the least important. Consider giving it up if necessary to save money for the rest of the auction.
* 2 - This item holds value but isn't a top priority for the bidder. Could bid on it if you have enough budget.
* 3 - This item is of utmost importance and is a top priority for the bidder in the rest of the auction.

You are {name}, who is attending an ascending-bid auction as a bidder. This auction will have some other bidders to compete with you in bidding wars. The price is gradually raised, bidders drop out until finally only one bidder remains, and that bidder wins the item at this final price. Remember: {desire_desc}.
Here are some must-know rules for this auction:
1. Item Values: The true value of an item means its resale value in the broader market, which you don't know. You will have a personal estimation of the item value. However, note that your estimated value could deviate from the true value, due to your potential overestimation or underestimation of this item.
2. Winning Bid: The highest bid wins the item. Your profit from winning an item is determined by the difference between the item's true value and your winning bid. You should try to win an item at a bid as minimal as possible to save your budget.

bias_ff (bool): Use bias for FF.
bias_attn (bool): Use bias for MHA.
causal (bool): Causal mask applied automatically.
past_context (int, optional): Receptive field for the causal mask, infinite if None.
custom (bool): Use custom MHA implementation, for testing / benchmarking.
memory_efficient (bool): Use xformers based memory efficient attention.
attention_as_float32 (bool): Perform the attention as float32
(especially important with memory_efficient as autocast won't do this automatically).
cross_attention (bool): If True, expect to get secondary input for cross-attention.
layer_scale (float, optional): If not None, LayerScale will be used

positional_embedding (str): Positional embedding strategy (sin, rope, or sin_rope).
max_period (float): Maximum period of the time embedding.
positional_scale (float): Scale of positional embedding, set to 0 to deactivate.
xpos (bool): Apply xpos exponential decay to positional embedding (rope only).
lr (float, optional): learning rate override through the `make_optim_group` API.
weight_decay (float, optional): Weight_decay override through the `make_optim_group` API.
layer_class: (subclass of `StreamingTransformerLayer): class to use
to initialize the layers, allowing further customization outside of AudioCraft.
checkpointing (str): Checkpointing strategy to reduce memory usage.
No checkpointing if set to 'none'. Per layer checkpointing using PyTorch
if set to 'torch' (entire layer checkpointed, i.e. linears are evaluated twice,
minimal memory usage, but maximal runtime). Finally, `xformers_default` provide
a policy for opting-out some operations of the checkpointing like
linear layers and attention, providing a middle ground between speed and memory.
device (torch.device, optional): Device on which to initialize.
dtype (torch.dtype, optional): dtype to use.
**kwargs: See `nn.TransformerEncoderLayer`.

"""Abstraction around providing pattern for interleaving codebooks.
The CodebooksPatternProvider abstraction allows to implement various strategies to
define interleaving pattern of sequences composed of multiple codebooks. For a given
number of codebooks `n_q`, the pattern provider can generate a specified pattern
corresponding to a sequence of `T` timesteps with `n_q` parallel codebooks. This pattern
can be used to construct a new sequence from the original codes respecting the specified
pattern. The pattern is defined as a list of list of code coordinates, code coordinate
being a tuple with the original timestep and codebook to build the new sequence.
Note that all patterns must start with an empty list that is then used to insert a first
sequence step of special tokens in the newly generated sequence.

that should be true for efficiency reason to avoid synchronization points.

"""
This is a nice wrapper around QEMU for both Python and interactive use.
The hope is to make it simple to configure QEMU in code, and then interact
with the resulting VM's control socket, serial port, SSH, or VNC. To use
the class, construct an instance. You must then perform the following
required configuration:
1. Disk configuration - use .hd() or .drive(). At least one disk argument
is required.
You may optionally do the following configurations:
1. Networking - default is none, but you can setup user networking
with SSH enabled:
.net_user(ssh=True|False)
2. VNC - default is off. Use .vnc_off() or .vnc_on() to change it.
3. Serial - default is "null", but can select:
.serial_stdio() - not a good idea for multiple threads
.serial_log(filename)
.serial_null()
4. Monitor - default is none, but can select:
.monitor_none()
.monitor_qmp(filename)
5. CDROM - add an ISO file / cdrom
6. Kernel - add a kernel + initrd + args

"""Compute finite difference approximation of the derivatives of a
vector-valued function.
If a function maps from R^n to R^m, its derivatives form m-by-n matrix
called the Jacobian, where an element (i, j) is a partial derivative of
f[i] with respect to x[j].
Parameters
----------
fun : callable
Function of which to estimate the derivatives. The argument x
passed to this function is ndarray of shape (n,) (never a scalar
even if n=1). It must return 1-D array_like of shape (m,) or a scalar.
x0 : array_like of shape (n,) or float
Point at which to estimate the derivatives. Float will be converted
to a 1-D array.
method : {'3-point', '2-point', 'cs'}, optional
Finite difference method to use:
- '2-point' - use the first order accuracy forward or backward
difference.
- '3-point' - use central difference in interior points and the
second order accuracy forward or backward difference
near the boundary.
- 'cs' - use a complex-step finite difference scheme. This assumes
that the user function is real-valued and can be
analytically continued to the complex plane. Otherwise,
produces bogus results.
rel_step : None or array_like, optional
Relative step size to use. If None (default) the absolute step size is
computed as ``h = rel_step * sign(x0) * max(1, abs(x0))``, with
`rel_step` being selected automatically, see Notes. Otherwise
``h = rel_step * sign(x0) * abs(x0)``. For ``method='3-point'`` the
sign of `h` is ignored. The calculated step size is possibly adjusted
to fit into the bounds.
abs_step : array_like, optional
Absolute step size to use, possibly adjusted to fit into the bounds.
For ``method='3-point'`` the sign of `abs_step` is ignored. By default
relative steps are used, only if ``abs_step is not None`` are absolute
steps used.
f0 : None or array_like, optional
If not None it is assumed to be equal to ``fun(x0)``, in this case
the ``fun(x0)`` is not called. Default is None.
bounds : tuple of array_like, optional
Lower and upper bounds on independent variables. Defaults to no bounds.
Each bound must match the size of `x0` or be a scalar, in the latter
case the bound will be the same for all variables. Use it to limit the
range of function evaluation. Bounds checking is not implemented
when `as_linear_operator` is True.
sparsity : {None, array_like, sparse matrix, 2-tuple}, optional
Defines a sparsity structure of the Jacobian matrix. If the Jacobian
matrix is known to have only few non-zero elements in each row, then
it's possible to estimate its several columns by a single function
evaluation [3]_. To perform such economic computations two ingredients
are required:
* structure : array_like or sparse matrix of shape (m, n). A zero
element means that a corresponding element of the Jacobian
identically equals to zero.
* groups : array_like of shape (n,). A column grouping for a given
sparsity structure, use `group_columns` to obtain it.
A single array or a sparse matrix is interpreted as a sparsity
structure, and groups are computed inside the function. A tuple is
interpreted as (structure, groups). If None (default), a standard
dense differencing will be used.
Note, that sparse differencing makes sense only for large Jacobian
matrices where each row contains few non-zero elements.
as_linear_operator : bool, optional
When True the function returns an `scipy.sparse.linalg.LinearOperator`.
Otherwise it returns a dense array or a sparse matrix depending on
`sparsity`. The linear operator provides an efficient way of computing
``J.dot(p)`` for any vector ``p`` of shape (n,), but does not allow
direct access to individual elements of the matrix. By default
`as_linear_operator` is False.
args, kwargs : tuple and dict, optional
Additional arguments passed to `fun`. Both empty by default.
The calling signature is ``fun(x, *args, **kwargs)``.
Returns
-------
J : {ndarray, sparse matrix, LinearOperator}
Finite difference approximation of the Jacobian matrix.
If `as_linear_operator` is True returns a LinearOperator
with shape (m, n). Otherwise it returns a dense array or sparse
matrix depending on how `sparsity` is defined. If `sparsity`
is None then a ndarray with shape (m, n) is returned. If
`sparsity` is not None returns a csr_matrix with shape (m, n).
For sparse matrices and linear operators it is always returned as
a 2-D structure, for ndarrays, if m=1 it is returned
as a 1-D gradient array with shape (n,).
See Also
--------
check_derivative : Check correctness of a function computing derivatives.
Notes
-----
If `rel_step` is not provided, it assigned as ``EPS**(1/s)``, where EPS is
determined from the smallest floating point dtype of `x0` or `fun(x0)`,
``np.finfo(x0.dtype).eps``, s=2 for '2-point' method and
s=3 for '3-point' method. Such relative step approximately minimizes a sum
of truncation and round-off errors, see [1]_. Relative steps are used by
default. However, absolute steps are used when ``abs_step is not None``.
If any of the absolute or relative steps produces an indistinguishable
difference from the original `x0`, ``(x0 + dx) - x0 == 0``, then a
automatic step size is substituted for that particular entry.
A finite difference scheme for '3-point' method is selected automatically.
The well-known central difference scheme is used for points sufficiently
far from the boundary, and 3-point forward or backward scheme is used for
points near the boundary. Both schemes have the second-order accuracy in
terms of Taylor expansion. Refer to [2]_ for the formulas of 3-point
forward and backward difference schemes.
For dense differencing when m=1 Jacobian is returned with a shape (n,),
on the other hand when n=1 Jacobian is returned with a shape (m, 1).
Our motivation is the following: a) It handles a case of gradient
computation (m=1) in a conventional way. b) It clearly separates these two
different cases. b) In all cases np.atleast_2d can be called to get 2-D
Jacobian with correct dimensions.

It is recommended to call :func:`.step()` for :class:`LinearWarmupCosineAnnealingLR`
after each iteration as calling it after each epoch will keep the starting lr at
warmup_start_lr for the first epoch which is 0 in most cases.
.. warning::
passing epoch to :func:`.step()` is being deprecated and comes with an EPOCH_DEPRECATION_WARNING.
It calls the :func:`_get_closed_form_lr()` method for this scheduler instead of
:func:`get_lr()`. Though this does not change the behavior of the scheduler, when passing
epoch param to :func:`.step()`, the user should call the :func:`.step()` function before calling
train and validation methods.
Example:
>>> layer = nn.Linear(10, 1)
>>> optimizer = Adam(layer.parameters(), lr=0.02)
>>> scheduler = LinearWarmupCosineAnnealingLR(optimizer, warmup_epochs=10, max_epochs=40)
>>> #
>>> # the default case
>>> for epoch in range(40):
... # train(...)
... # validate(...)
... scheduler.step()
>>> #
>>> # passing epoch param case
>>> for epoch in range(40):
... scheduler.step(epoch)
... # train(...)
... # validate(...)

alpha (float): The alpha factor in Focal Loss calculation.
gamma (float): The gamma factor in Focal Loss calculation.
Methods:
forward(pred_bboxes, pred_scores, gt_bboxes, gt_cls, gt_groups, masks=None, gt_mask=None): Computes the assignment
between predictions and ground truths for a batch.

class MyDistributedSampler(Sampler[T_co]):
r"""Sampler that restricts data loading to a subset of the dataset.
It is especially useful in conjunction with
:class:`torch.nn.parallel.DistributedDataParallel`. In such a case, each
process can pass a :class:`~torch.utils.data.DistributedSampler` instance as a
:class:`~torch.utils.data.DataLoader` sampler, and load a subset of the
original dataset that is exclusive to it.
.. note::
Dataset is assumed to be of constant size and that any instance of it always
returns the same elements in the same order.
Args:
dataset: Dataset used for sampling.
num_replicas (int, optional): Number of processes participating in
distributed training. By default, :attr:`world_size` is retrieved from the
current distributed group.
rank (int, optional): Rank of the current process within :attr:`num_replicas`.
By default, :attr:`rank` is retrieved from the current distributed
group.
shuffle (bool, optional): If ``True`` (default), sampler will shuffle the
indices.
seed (int, optional): random seed used to shuffle the sampler if
:attr:`shuffle=True`. This number should be identical across all
processes in the distributed group. Default: ``0``.
drop_last (bool, optional): if ``True``, then the sampler will drop the
tail of the data to make it evenly divisible across the number of
replicas. If ``False``, the sampler will add extra indices to make
the data evenly divisible across the replicas. Default: ``False``.
padding: (bool, optional): Whether to pad the dataset. Default: ``True``.
pair: (bool, optional): Pair output for Mixup. Default: ``False``.
.. warning::
In distributed mode, calling the :meth:`set_epoch` method at
the beginning of each epoch **before** creating the :class:`DataLoader` iterator
is necessary to make shuffling work properly across multiple epochs. Otherwise,
the same ordering will be always used.
Example::
>>> sampler = DistributedSampler(dataset) if is_distributed else None
>>> loader = DataLoader(dataset, shuffle=(sampler is None),
... sampler=sampler)
>>> for epoch in range(start_epoch, n_epochs):
... if is_distributed:
... sampler.set_epoch(epoch)
... train(loader)

Every child class has to implement the following attributes:
- signatures: pd.DataFrame
The signature matrix including mutation type names and signature names
- exposures: pd.DataFrames
The exposure matrix including the signature names and sample names
- _n_parameters: int
The number of parameters fitted by the NMF algorithm.
This is needed to compute the Bayesian Information Criterion (BIC)
- reconstruction_error: float
The reconstruction error between the count matrix and
the reconstructed count matrix.
- samplewise_reconstruction_error: np.ndarray
The samplewise reconstruction error between the sample counts and
the reconstructed sample counts.
- objective: str
"minimize" or "maximize". Whether the NMF algorithm maximizes or
minimizes the objective function. Some algorithms maximize a likelihood,
others minimize a distance. The distinction is useful for filtering NMF runs
based on the fitted objective function value downstream.
- corr_signatures: pd.DataFrame
The signature correlation matrix
- corr_samples: pd.DataFrame
The sample correlation matrix
Every child class has to implement the following methods:
- objective_fuction:
The objective function to optimize when running the algorithm
- loglikelihood:
The loglikelihood of the underyling generative model
- _initialize:
A method to initialize all model parameters before fitting
- fit:
Run the NMF algorithm for a given mutation count data. Every
fit method should also implement a version that allows fixing
arbitrary many a priori known signatures.
- _get_embedding_data:
A helper function for the embedding plot
- _get_default_embedding_annotations:
A helper function for the embedding plot
The following attributes and methods are implemented in SignatureNMF:
- data_reconstructed: pd.DataFrame
The recovered mutation count data given
the current signatures and exposures.
- X_reconstructed: np.ndarray
The recovered mutation count matrix given
the current signatures and exposures
- bic: float
The value of the Bayesian Information Criterion (BIC)
- _setup_data_parameters:
Perform parameter checks on the input data and add attributes
- plot_history:
Plot the history of the objective function values after fitting the model
- plot_signatures:
Plot the signatures using the signatures_plot function implemented in
the plot module
- plot_correlation:
Plot the correlation of either the signatures or exposures
using the corr_plot function implemented in the plot module
- plot_embeddings:
Plot the sample (and potentially the signature) embeddings in 2D
using PCA, tSNE or UMAP

Annotations per data point, e.g. the sample names. If None,
the algorithm-specific default annotations are used.
For example, CorrNMF annotates the signature embeddings by default.
Note that there are 'n_signatures' + 'n_samples' data points in CorrNMF,
i.e. the first 'n_signatures' elements in 'annotations'
are the signature annotations, not any sample annotations.
outfile : str, default=None
If not None, the figure will be saved in the specified file path.

r"""
The abstract class CorrNMF unifies the structure of deterministic and
stochastic algorithms to fit the parameters of correlated NMF (CorrNMF).
The model parameters are the signature and sample biases, the variance, and the
signature matrix. The latent variables are the signature and sample embeddings.
Overview:
Every child class has to implement the following methods:
- _update_alpha:
update the sample exposure biases \alpha
- _update_beta:
update the signature exposure biases \beta
| - _update_sigma_sq: |

"""
Data loader. Combines a dataset and a sampler, and provides
single- or multi-process iterators over the dataset.
Note: The only difference with default pytorch DataLoader is that an additional option stack_dim is available to
select along which dimension the data should be stacked to form a batch.
Arguments:
dataset (Dataset): dataset from which to load the data.
batch_size (int, optional): how many samples per batch to load
(default: 1).
shuffle (bool, optional): set to ``True`` to have the data reshuffled
at every epoch (default: False).
sampler (Sampler, optional): defines the strategy to draw samples from
the dataset. If specified, ``shuffle`` must be False.
batch_sampler (Sampler, optional): like sampler, but returns a batch of
indices at a time. Mutually exclusive with batch_size, shuffle,
sampler, and drop_last.
num_workers (int, optional): how many subprocesses to use for data
loading. 0 means that the data will be loaded in the main process.
(default: 0)
collate_fn (callable, optional): merges a list of samples to form a mini-batch.
stack_dim (int): Dimension along which to stack to form the batch. (default: 0)
pin_memory (bool, optional): If ``True``, the data loader will copy tensors
into CUDA pinned memory before returning them.
drop_last (bool, optional): set to ``True`` to drop the last incomplete batch,
if the dataset size is not divisible by the batch size. If ``False`` and
the size of dataset is not divisible by the batch size, then the last batch
will be smaller. (default: False)
timeout (numeric, optional): if positive, the timeout value for collecting a batch
from workers. Should always be non-negative. (default: 0)
worker_init_fn (callable, optional): If not None, this will be called on each
worker subprocess with the worker id (an int in ``[0, num_workers - 1]``) as
input, after seeding and before data loading. (default: None)
.. note:: By default, each worker will have its PyTorch seed set to
``base_seed + worker_id``, where ``base_seed`` is a long generated
by main process using its RNG. However, seeds for other libraries
may be duplicated upon initializing workers (w.g., NumPy), causing
each worker to return identical random numbers. (See
:ref:`dataloader-workers-random-seed` section in FAQ.) You may
use ``torch.initial_seed()`` to access the PyTorch seed for each
worker in :attr:`worker_init_fn`, and use it to set other seeds
before data loading.
.. warning:: If ``spawn`` start method is used, :attr:`worker_init_fn` cannot be an
unpicklable object, e.g., a lambda function.

r"""
encoder_hidden_states (:obj:`torch.FloatTensor` of shape :obj:`(batch_size, sequence_length, hidden_size)`, `optional`):
Sequence of hidden-states at the output of the last layer of the encoder. Used in the cross-attention if
the model is configured as a decoder.
encoder_attention_mask (:obj:`torch.FloatTensor` of shape :obj:`(batch_size, sequence_length)`, `optional`):
Mask to avoid performing attention on the padding token indices of the encoder input. This mask is used in
the cross-attention if the model is configured as a decoder. Mask values selected in ``[0, 1]``:
- 1 for tokens that are **not masked**,
- 0 for tokens that are **masked**.
labels (:obj:`torch.LongTensor` of shape :obj:`(batch_size, sequence_length)`, `optional`):
Labels for computing the left-to-right language modeling loss (next word prediction). Indices should be in
``[-100, 0, ..., config.vocab_size]`` (see ``input_ids`` docstring) Tokens with indices set to ``-100`` are
ignored (masked), the loss is only computed for the tokens with labels n ``[0, ..., config.vocab_size]``
past_key_values (:obj:`tuple(tuple(torch.FloatTensor))` of length :obj:`config.n_layers` with each tuple having 4 tensors of shape :obj:`(batch_size, num_heads, sequence_length - 1, embed_size_per_head)`):
Contains precomputed key and value hidden states of the attention blocks. Can be used to speed up decoding.
If :obj:`past_key_values` are used, the user can optionally input only the last :obj:`decoder_input_ids`
(those that don't have their past key value states given to this model) of shape :obj:`(batch_size, 1)`
instead of all :obj:`decoder_input_ids` of shape :obj:`(batch_size, sequence_length)`.
use_cache (:obj:`bool`, `optional`):
If set to :obj:`True`, :obj:`past_key_values` key value states are returned and can be used to speed up
decoding (see :obj:`past_key_values`).
Returns:
Example::
>>> from transformers import BertTokenizer, BertLMHeadModel, BertConfig
>>> import torch
>>> tokenizer = BertTokenizer.from_pretrained('bert-base-cased')
>>> config = BertConfig.from_pretrained("bert-base-cased")
