[BUG-REPORT] ImportError when importing vaex

[marijnkj]

I installed vaex in a conda environment with python 3.6.13. My vaex versions are:

vaex                      4.5.0              pyhd8ed1ab_0
vaex-astro                0.8.3              pyhd8ed1ab_0
vaex-core                 4.5.1            py36h52d1fc4_0
vaex-hdf5                 0.10.0             pyhd8ed1ab_0
vaex-jupyter              0.6.0              pyhd8ed1ab_0
vaex-ml                   0.14.0             pyhd8ed1ab_0
vaex-server               0.6.1              pyhd8ed1ab_0
vaex-viz                  0.5.0              pyhd8ed1ab_0

When I call import vaex, the following error is thrown:

ERROR:MainThread:vaex:issue loading plot

    from . import _imaging as core
ImportError: DLL load failed: The specified module could not be found.

I'm on Windows 11 (Home), have tried starting VSCode from the anaconda prompt with the environment activated, but otherwise really don't know how to fix this issue!

this is not an issue with vaex. if you look at the last line of this traceback, you see that the error happens while PIL is trying to import its relative module _imaging. try pip install --force-reinstall PIL
