Incompatibility with Numpy2.0
Author: r-menezesCreated Oct 7, 2024Updated Jul 20, 2025
Hi, LaTeX-OCR is a blessing! Thank you so much for making it available. After upgrading my conda installation, I found the following problem related to the usage of an older version of numpy that does not seem to be supported:
A module that was compiled using NumPy 1.x cannot be run in NumPy 2.1.1 as it may crash. To support both 1.x and 2.x versions of NumPy, modules must be compiled with NumPy 2.0. Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.
If you are a user of the module, the easiest solution will be to downgrade to 'numpy<2' or try to upgrade the affected module. We expect that some modules will need time to support NumPy 2.

ImportError: numpy.core.multiarray failed to importlater I might try to implement the suggested changes of imposing a numpy version.
