# CSP-Darknet-53 Mish model |
|
|
|
Pretrained on [ImageNette](https://github.com/fastai/imagenette). The CSP-Darknet-53 Mish architecture was introduced in [this paper](https://arxiv.org/pdf/1911.11929.pdf). |
|
|
|
|
|
## Model description |
|
|
|
The core idea of the author is to change the convolutional stage by adding cross stage partial blocks in the architecture and replace activations with Mish. |
|
|
|
|
|
## Installation |
|
|
|
### Prerequisites |
|
|
|
Python 3.6 (or higher) and [pip](https://pip.pypa.io/en/stable/)/[conda](https://docs.conda.io/en/latest/miniconda.html) are required to install Holocron. |
|
|
|
### Latest stable release |
|
|
|
You can install the last stable release of the package using [pypi](https://pypi.org/project/pylocron/) as follows: |
|
|
|
```shell |
|
pip install pylocron |
|
``` |
|
|
|
or using [conda](https://anaconda.org/frgfm/pylocron): |
|
|
|
```shell |
|
conda install -c frgfm pylocron |
|
``` |
|
|
|
### Developer mode |
|
|
|
Alternatively, if you wish to use the latest features of the project that haven't made their way to a release yet, you can install the package from source *(install [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git) first)*: |
|
|
|
```shell |
|
git clone https://github.com/frgfm/Holocron.git |
|
pip install -e Holocron/. |
|
``` |
|
|
|
|
|
## Usage instructions |
|
|
|
```python |
|
from PIL import Image |
|
from torchvision.transforms import Compose, ConvertImageDtype, Normalize, PILToTensor, Resize |
|
from torchvision.transforms.functional import InterpolationMode |
|
from holocron.models import model_from_hf_hub |
|
|
|
model = model_from_hf_hub("frgfm/cspdarknet53_mish").eval() |
|
|
|
img = Image.open(path_to_an_image).convert("RGB") |
|
|
|
# Preprocessing |
|
config = model.default_cfg |
|
transform = Compose([ |
|
Resize(config['input_shape'][1:], interpolation=InterpolationMode.BILINEAR), |
|
PILToTensor(), |
|
ConvertImageDtype(torch.float32), |
|
Normalize(config['mean'], config['std']) |
|
]) |
|
|
|
input_tensor = transform(img).unsqueeze(0) |
|
|
|
# Inference |
|
with torch.inference_mode(): |
|
output = model(input_tensor) |
|
probs = output.squeeze(0).softmax(dim=0) |
|
``` |
