Hi, I just noticed that when I check sys.executable from Slicer I get: import sys; print(sys.executable) C:/Users/kerim/AppData/Local/NA-MIC/Slicer 5.0.2/bin/PythonSlicer.exe But if I run PythonSlicer and then run the same command I get real executable: import sys; print(sys.executable) C:\Users…

When using PythonSlicer, setting PYTHONSTARTUP works as expected. When using Slicer, there are no support for PYTHONSTARTUP environment variable because Slicer application embeds the python library and the logic handling PYTHONSTARTUP (specific to the python interpreter) is not considered. In the …
