Hi,

I have some issue with the latest released version (2.3.0) and
manually build Python 2.7.15, 3.5.2 and 3.6.6 on our CentOS-7 machines.

[tru@sillage ~]$ module add pymol/release/2.3.0-Python-3.6.6
[tru@sillage ~]$ module li
Currently Loaded Modulefiles:
  1) Python/3.6.6                       3) pymol/release/2.3.0-Python-3.6.6
  2) msgpack/2.1.5
[tru@sillage ~]$ pymol
Qt not available, using GLUT/Tk interface
[tru@sillage ~]$ echo $?
0

The different Python versions are isolated through the environment
modules and the issue has only appeared with 2.3.0 and all the python
versions except the version using the system provided python version.

these fails:
pymol/release/2.3.0-Python-2.7.15  pymol/release/2.3.0-Python-3.6.6
pymol/release/2.3.0-Python-3.5.2 

this works:
pymol/release/2.3.0-Python-centos7

[tru@sillage ~]$ module add pymol/release/2.3.0-Python-centos7
[tru@sillage ~]$ pymol

and all the previous versions of pymol are perfectly fine...

pymol/release/1.8.7-Python-2.7.12  pymol/release/2.1.0-Python-3.6.6
pymol/release/1.8.7-Python-2.7.15  pymol/release/2.1.0-Python-centos7

pymol/release/1.8.7-Python-3.6.3   pymol/release/2.2.0-Python-3.5.2
pymol/release/1.8.7-Python-3.6.6   pymol/release/2.2.0-Python-3.6.6
pymol/release/1.8.7-Python-centos7 pymol/release/2.2.0-Python-centos7
pymol/release/2.1.0-Python-2.7.12  
pymol/release/2.1.0-Python-2.7.15  
pymol/release/2.1.0-Python-3.5.2   
pymol/release/2.1.0-Python-3.6.3   

Any idea where I can start looking at?

python3 build process details:
module purge && module add Python/${PYTHON_V}
python3 setup.py build
python3 setup.py install --prefix=/....

for python2, I just resplaced python3 by python in the lines above.

Any idea what could be causing this behaviour?

Cheers

Tru
