Repvgg A0

🚀 RepVGG-A0 model

This is a pre-trained RepVGG-A0 model on ImageNette. The RepVGG architecture was introduced in this paper, offering a novel approach to image classification.

✨ Features

• Distinct Training and Inference Architectures: The core idea is to differentiate the training architecture (with shortcut connections) from the inference one (a pure highway network).
• Reparametrization: The training architecture can be reparametrized into a simple sequence of convolutions and non - linear activations by designing the residual block.

📦 Installation

Prerequisites

Python 3.6 (or higher) and pip/conda are required to install Holocron.

Latest stable release

You can install the last stable release of the package using pypi as follows:

pip install pylocron

or using conda:

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 first):

git clone https://github.com/frgfm/Holocron.git
pip install -e Holocron/.

💻 Usage Examples

Basic Usage

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/repvgg_a0").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)
