Solutions
SystemError from numba.np.ufunc import _internal: _internal initialization failed without throwing an exception
Solution
T1, pip or conda download and install directly
1. Install g++
The g++ compiler is not installed, pytensor needs to use g++ to compile the C extension. It is recommended to install g++
to check the compilation toolchain: make sure that the compilation toolchain has been configured correctly before using numba
. For Windows users, you can install m2w64-toolchain.
conda install m2w64-toolchain2. It is recommended to reinstall numba
PyMC depends on numba, but the import of numba fails
pip install numba --upgrade
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple numba --upgradeor
conda install numba
conda update numba
3. If the error is still reported
You can try to delete PyMC and Numba in the site-packages directory and completely reinstall:
pip uninstall pymc numba -yT2, directly create a new conda environment to install all dependencies
to try to create a new conda environment, and then install all dependencies in that environment
conda create -n py39_pymc_env python=3.9
conda activate py39_pymc_env
conda install m2w64-toolchain # or g++
pip install numba
pip install pymc
