FAQ
==========================

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.

.. code:: bash

   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:
https://github.com/opendatalab/MinerU/issues/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:

.. code:: json

   {
     "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.

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:

.. code:: bash

   sudo apt-get install libgl1-mesa-glx

Reference: https://github.com/opendatalab/MinerU/issues/388

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

You need to uninstall the module and reinstall it:

.. code:: bash

   pip uninstall fairscale
   pip install fairscale

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.

.. code:: bash

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