I'm constantly enhancing these model descriptions to provide you with the most relevant and comprehensive information

# open-llama-7b-v2-open-instruct - GGUF
- Model creator: [VMware](https://huggingface.co/VMware)
- Original model: [open-llama-7b-v2-open-instruct](https://huggingface.co/VMware/open-llama-7b-v2-open-instruct)

OpenLlama is a free reimplementation of the original Llama Model which is licensed under Apache 2 license.



# About GGUF format

`gguf` is the current file format used by the [`ggml`](https://github.com/ggerganov/ggml) library.
A growing list of Software is using it and can therefore use this model.
The core project making use of the ggml library is the [llama.cpp](https://github.com/ggerganov/llama.cpp) project by Georgi Gerganov

# Quantization variants

There is a bunch of quantized files available to cater to your specific needs. Here's how to choose the best option for you:

# Legacy quants

Q4_0, Q4_1, Q5_0, Q5_1 and Q8 are `legacy` quantization types.
Nevertheless, they are fully supported, as there are several circumstances that cause certain model not to be compatible with the modern K-quants.
## Note:
Now there's a new option to use K-quants even for previously 'incompatible' models, although this involves some fallback solution that makes them not *real* K-quants. More details can be found in affected model descriptions.
(This mainly refers to Falcon 7b and Starcoder models)

# K-quants

K-quants are designed with the idea that different levels of quantization in specific parts of the model can optimize performance, file size, and memory load.
So, if possible, use K-quants.
With a Q6_K, you'll likely find it challenging to discern a quality difference from the original model - ask your model two times the same question and you may encounter bigger quality differences.

# Original Model Card:
# VMware/open-llama-7B-v2-open-instruct
Instruction-tuned version of the fully trained Open LLama 7B v2  model. The model is open for <b>COMMERCIAL USE</b>. <br>

- This model performs better on code compared to v1 due to the improvements made on the base model by the openlm-research team.
- The instruction model is trained on an improved instruction tuning dataset compared to v1

**NOTE**: The model was trained using the Alpaca prompt template <br>
**NOTE**: Fast tokenizer results in incorrect encoding, set the ```use_fast = False``` parameter, when instantiating the tokenizer

## Use in Transformers

```
import os

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = 'VMware/open-llama-7b-v2-open-instruct'


tokenizer = AutoTokenizer.from_pretrained(model_name, use_fast=False)

model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.float16, device_map='sequential')

prompt_template = "Below is an instruction that describes a task. Write a response that appropriately completes the request.\n\n### Instruction:\n{instruction}\n\n### Response:"

prompt = """What is attention mechanism of a transformer model? 
 Write a python code to illustrate how attention works within a transformer model using numpy library. Donot use pytorch or tensorflow."""


inputt = prompt_template.format(instruction= prompt)
input_ids = tokenizer(inputt, return_tensors="pt").input_ids.to("cuda")

output1 = model.generate(input_ids, max_length=512)
input_length = input_ids.shape[1]
output1 = output1[:, input_length:]
output = tokenizer.decode(output1[0])

print(output)

```


### Output

Sure, I can help you with that!

Attention mechanisms in transformer models are typically implemented using the attention mechanism in the self-attention layer. Self-attention allows the model to focus on different parts of the input sequence when processing it. This is achieved by computing a set of attention weights, which are used to weigh the contribution of each input element to the output.

Here's an example code using NumPy to illustrate how attention works in a transformer model:

```python
import numpy as np

def attention_weights(query, key, value, mask):
    # Query, key, and value are input tensors. Mask is a tensor of zeros and ones that represents the attention mask.
    # It is used to prevent the model from attending to certain positions in the input sequence if they are not relevant.
    # The attention weights are the element-wise product of the query, key, and mask tensors.
    # The result is a tensor of the same shape as the query tensor.
    
    # Compute the dot product between the query tensor and the key tensor
    dot = np.matmul(query, key)
    
    # Compute the element-wise softmax of the dot product tensor
    exp_dot = np.exp(dot)
    
    # Multiply the dot product and the softmax of the dot product tensors
    weights = dot * exp_dot
    
    # Return the attention weights as a NumPy tensor
    return weights

# Define the input sequence
query = np.array([[0.1, 0.2, 0.3], [0.4, 0.5, 0.6]])
key = np.array([[0.1, 0.2], [0.3, 0.4]])
value = np.array([[0.1, 0.2, 0.3], [0.4, 0.5, 0.6]])
mask = np.array([[False, True, True], [False, True, True]])

# Compute the attention weights
weights = attention_weights(query, key, value, mask)

# Print the attention weights
print(weights)
```

In this example, the `attention_weights` function takes as input the query tensor, key tensor, value tensor, and mask tensor. It computes the dot product between the query and key tensors using the `np.matmul` function, and then applies a softmax function using the `np.exp` function to the element-wise dot product tensor. It then multiplies the dot product and softmax tensors using the `np.matmul` function, and returns the result as a NumPy tensor.

The `query`, `key`, and `value` tensors represent the input sequence to the transformer model. The `mask` tensor represents the attention mask, which is used to prevent the model from attending to certain positions in the input sequence if they are not relevant.

The output of the `attention_weights` function is a NumPy tensor that represents the attention weights for the input sequence. These weights are used by the transformer model to weigh the contribution of each input element to the output.

I hope this helps!</s>

## Please consider to support my work
**Coming Soon:** I'm in the process of launching a sponsorship/crowdfunding campaign for my work. I'm evaluating Kickstarter, Patreon, or the new GitHub Sponsors platform, and I am hoping for some support and contribution to the continued availability of these kind of models. Your support will enable me to provide even more valuable resources and maintain the models you rely on. Your patience and ongoing support are greatly appreciated as I work to make this page an even more valuable resource for the community.
