[!TIP]
If you're using Windows and cannot open the file after downloading, please install vc_redist.x64.exe and try again.
If you cannot access Docker Hub, please try the image on GitHub Container Registry.
docker pull ghcr.io/byaidu/pdfmathtranslate docker run -d -p 7860:7860 ghcr.io/byaidu/pdfmathtranslate
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.
Execute the translation command in the command line to generate the translated document example-mono.pdf and the bilingual document example-dual.pdf in the current working directory. Use Google as the default translation service. More support translation services can find HERE.
