Numba "SystemError: initialization of _internal failed without raising an exception"

[mposter1]

While attempting to use cam-control on a win7-64x machine running python 3.8.10, control.exe, in addition to control-console.exe, was throwing the error,

"SystemError: initialization of _internal failed without raising an exception,"

from the Numba package.

I wrapped the entire control.py script in a try-except statement to actually capture the error, as control.exe quickly shuts down after erroring out.

After some googling, the error seemed to be caused by incompatible an incompatible numpy version.

I then resolved the issue by removing my local numpy installation from C:\Users*insert-username*\AppData\Roaming\Python\Python38\site-packages, and control.exe now runs without erroring.

I would like to restore the local numpy installation. I would welcome any thoughts on a solution. I've attached the stack trace below. Thanks!

That seems a bit strange, since cam-control (at least, when launched using control.exe or control-console.exe) is supposed to run in a completely separate Python interpreter, the one in the python subfolder. Could you check the errlog.txt file in the inner cam-control subfolder (the one containing the .py files) and see that the only errors there are indeed the numba-related ones?

To fix the issue, you can try running local-python.cmd within the local Python folder, which designates this Python interpreter as the default one. From there you can manage the install packages using pip. Something like python.exe -m pip install numba==0.53.1 numpy==1.22.0 might be able to solve the problem.
