Error when extecuting SimBA.py

[Ejdrup]

When executing SimBA.py I get the following error:

My input:
C:\ProgramData\simba\simba>python SimBA.py
Error output:

C:\ProgramData\simba\simba>python SimBA.py
ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'
ImportError: numpy.core.multiarray failed to import

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 960, in _find_and_load
SystemError: <class '_frozen_importlib._ModuleLockManager'> returned a result with an error set
ImportError: numpy.core._multiarray_umath failed to import
ImportError: numpy.core.umath failed to import

Passing:

python
import numpy as np
np.__version__

returns 1.14.5, which is what is specified in the requirements.txt.

After chewing myself through every requirement that wasn't the correct version I finally got it to work. In short, the supplied requirements.txt did not contain a setup of versions that worked for me.

Hi @Ejdrup thanks for reporting this - yes SimBA requires numpy 1.18.1, which seems to be the numpy version specified in the requirements.txt.

For anyone else seeing this error at startup, run:
pip install numpy==1.18.1

If the numpy install failed, there is risk the installation of correct versions of pandas/pytables also may have failed which could cause errors further down the line. For the correct versions of pandas/pytables, run:

pip install pandas==0.25.3
pip install tables==3.5.1

Thanks again
