[chimera-dev] Running Chimera through Python script

Hi - I’m trying to follow Example 1 on http://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/Examples/index.html <http://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/Examples/index.html>, but after entering the code precisely as it is written, am getting back the ModuleNotFoundError: No module named ‘chimera’. I’ve tried running the script using both Python2.7 and Python3, and both have resulted in the same error. As a sub-question, is Chimera supported in Python3, or is it best practice to still use Python2? Thank you, Evan Seitz Chimera version: 1.12.0 OS: macOS High Sierra 10.13.2
