Python Intel Mkl Fatal Error: Cannot Load Mkl_intel_thread.dll

Using Anaconda, Python has a problem whenever I import Pandas, Numpy, Matplotlib, etc.: python.exe - Ordinal Not Found The ordinal 242 could not be located in the dynamic link lib

Solution 1:

It's known DLL version conflict. There is workaround described in anaconda's docs: https://conda.io/projects/conda/en/latest/user-guide/troubleshooting.html#numpy-mkl-library-load-failed

On windows, just run set CONDA_DLL_SEARCH_MODIFICATION_ENABLE=1 in command prompt before using python.

Solution 2:

pip uninstall numpy
pip install numpy

it's work for me,uninstall conda environment package "numpy" and reinstall latest edition.
