Fatal Python error: PyThreadState_Get: no current thread

[christianbrodbeck]

Issue:

I currently get the error below from a direct installation of vtk from conda-forge. This did not use to happen, so I'm wondering whether it's related to a system update or update in some other package. It happens on both Macs I'm using (10.14.3 (18D42) and 10.14.2 (18C54)). Can others replicate?

$ conda create -n vtk_test -c conda-forge vtk 
...
$ conda activate vtk_test
$ python -c "import vtk"
Fatal Python error: PyThreadState_Get: no current thread

Abort trap: 6

[looooo]

can you try latest available vtk-package (8.2.0)?

No more error, the issue seems to be fixed.
