<br>
>From what I’ve read online it sounds like this is due to a python mismatch, i.e. building VTK against a different python version than the version it is run under. I’ve searched through the advanced cmake configuration and can’t find any reference to the system built-in python2 interpreter.<br>
<br>
Any suggestions on what might be going wrong?<br>
<br>
Thanks!<br>
