Requirements

• Check the requirements.txt file.
• For ONNX, if you have a NVIDIA GPU, then install the onnxruntime-gpu, otherwise use the onnxruntime library.
• Additionally, pafy and youtube-dl are required for youtube video inference.

Installation

git clone https://github.com/ibaiGorordo/ONNX-TopFormer-Semantic-Segmentation.git
cd ONNX-TopFormer-Semantic-Segmentation
pip install -r requirements.txt

ONNX Runtime

For Nvidia GPU computers: pip install onnxruntime-gpu

Otherwise: pip install onnxruntime

For youtube video inference

pip install youtube_dl
pip install git+[https://github.com/zizo-pro/pafy@b8976f22c19e4ab5515cacbfae0a3970370c102b](https://github.com/zizo-pro/pafy@b8976f22c19e4ab5515cacbfae0a3970370c102b)

ONNX model

The model was converted from the Pytorch implementation using the code in the original repository. Download the converted ONNX model from the drive file and save them into the models folder.
