That’s very bad because many internal libraries are broken and we can’t load them and any related libraries from PYTHONPATH. And that’s [almost] impossible to replace all of them by not related libraries from PYTHONPATH.

One more thing: this binary lib can be loaded without issues:
`from numpy import linalg`
Also, I can remove “scipy” internal package manually and load it from external PYTHONPATH.

Very strange, I can run `from scipy import linalg` without any error.
Please share what `otool -L /Applications/ParaView-5.7.0-1035-g5b9485e246.app/Contents/MacOS/paraview` reports.

As I mentioned over in [this thread](https://discourse.paraview.org/t/paraview-5-7-doesnt-work-scipy-internal-python-module/3267/14), the fact that it is looking for `_main` is very odd. Does this still occur today?

@ben.boeckel I’m still getting this issue.

Thoughts @chuckatkins? Have you seen this with BLAS/LAPACK elsewhere?
I’m not seeing much else on a search, so I assume we’re building scipy wrong in some way here, but we’re just using `python setup.py` subcommands, so I’m at a loss ☹ .
