Unable to install?
The present program needs an AI model(wybxc/DocLayout-YOLO-DocStructBench-onnx) before working and some users are not able to download due to network issues. If you have a problem with downloading this model, we provide a workaround using the following environment variable:
set HF_ENDPOINT=https://hf-mirror.com
For PowerShell user:
$env:HF_ENDPOINT = https://hf-mirror.com
If the solution does not work to you / you encountered other issues, please refer to frequently asked questions.
