• The input images are directly resized to match the input size of the model. I skipped adding the pad to the input image, it might affect the accuracy of the model if the input image has a different aspect ratio compared to the input size of the model. Always try to get an input size with a ratio close to the input images you will use.

• 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.

git clone https://github.com/ibaiGorordo/ONNX-YOLOv7-Object-Detection.git
cd ONNX-YOLOv7-Object-Detection
pip install -r requirements.txt

For Nvidia GPU computers: pip install onnxruntime-gpu

Otherwise: pip install onnxruntime

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

The original models were converted to different formats (including .onnx) by PINTO0309. Download the models from [his repository](https://github.com/PINTO0309/PINTO_model_zoo/tree/main/307_YOLOv7). For that, you can either run the download_single_batch.sh or copy the google drive link inside that script in your browser to manually download the file. Then, extract and copy the downloaded onnx models (for example yolov7-tiny_480x640.onnx) to your models directory, and fix the file name in the python scripts accordingly.
