##### 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:

```shell
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.
