Frequently Asked Questions

1. When using the command pip install magic-pdf[full] on newer versions of macOS, the error zsh: no matches found: magic-pdf[full] occurs.

On macOS, the default shell has switched from Bash to Z shell, which has special handling logic for certain types of string matching. This can lead to the "no matches found" error. You can try disabling the globbing feature in the command line and then run the installation command again.

setopt no_nomatch
pip install magic-pdf[full]

2. Encountering the error pickle.UnpicklingError: invalid load key, 'v'. during use

This might be due to an incomplete download of the model file. You can try re-downloading the model file and then try again. Reference: #143

3. Where should the model files be downloaded and how should the /models-dir configuration be set?

The path for the model files is configured in "magic-pdf.json". just like:

{
  "models-dir": "/tmp/models"
}

This path is an absolute path, not a relative path. You can obtain the absolute path in the models directory using the "pwd" command. Reference: #155 (comment)

4. Encountered the error ImportError: libGL.so.1: cannot open shared object file: No such file or directory in Ubuntu 22.04 on WSL2

The libgl library is missing in Ubuntu 22.04 on WSL2. You can install the libgl library with the following command to resolve the issue:

sudo apt-get install libgl1-mesa-glx

Reference: #388

5. Encountered error ModuleNotFoundError: No module named 'fairscale'

You need to uninstall the module and reinstall it:

pip uninstall fairscale
pip install fairscale

Reference: #411

6. On some newer devices like the H100, the text parsed during OCR using CUDA acceleration is garbled.

The compatibility of cuda11 with new graphics cards is poor, and the CUDA version used by Paddle needs to be upgraded.

pip install paddlepaddle-gpu==3.0.0b1 -i https://www.paddlepaddle.org.cn/packages/stable/cu123/

Reference: #558

7. On some Linux servers, the program immediately reports an error Illegal instruction (core dumped)

This might be because the server's CPU does not support the AVX/AVX2 instruction set, or the CPU itself supports it but has been disabled by the system administrator. You can try contacting the system administrator to remove the restriction or change to a different server.
