We were having difficulty running a script using

/Applications/ParaView-5.8.0.app/Contents/MacOS/paraview --script=...

The application would hang (OS-X spinner shown indefinitely). We suspect that the issue may involve importing numpy. If we execute

/Applications/ParaView-5.8.0.app/Contents/bin/pvpython

or

/Applications/ParaView-5.8.1.app/Contents/bin/pvpython

and enter import numpy, we are not returned a python command prompt (import six works as expected). This behavior was found on OS-X 10.15.4 and 10.15.6. The stack trace that is shown when we enter CTRL-C is shown below. On OS-X 10.14, I get a different error, which is shown below. To further complicate matters, I don't have this issue on a mac mini running OS-X 10.15.5. I don't know if the explanation involves the fact that the failures were observed on macbook pros or if there is something special about OS-X 10.15.5 (I am not given the option to install 10.15.5 on the macbook pro.)

If we do the same using

/Applications/ParaView-5.7.0.app/Contents/bin/pvpython

numpy imports as expected.
