[Rtk-users] Python terminal closes unexpectedly when calling rtk functions

[Simon Rit]

Hi,
Can you list your itk packages with the corresponding versions (pip list |
grep itk)? ITK has recently released new packages and the "old" RTK
packages might be incompatible... To avoid this, you can specify that the
previous RC version of ITK should be used, i.e. 5.4rc1. Can you confirm
that this is the problem? In which case, I'll quickly work on new RTK
packages.
Thanks for the report,
Simon
