How to set correct Python path and Kratos path in GiD

[veiguf]

Hi, I successfully compiled Kratos in Ubuntu 24.04 and from terminal it works fine.
can you please help me to set the correct Python path and Kratos path in GiD?

Here what I tried:

And here the resulting error:

Python path configuration:
  PYTHONHOME = '/usr/bin'
  PYTHONPATH = '/home/veit/opt/Kratos/bin/Release:'
  program name = '/usr/bin/python3.11'
  isolated = 0
  environment = 1
  user site = 1
  safe_path = 0
  import site = 1
  is in build tree = 0
  stdlib dir = '/usr/bin/lib/python3.11'
  sys._base_executable = '/usr/bin/python3.11'
  sys.base_prefix = '/usr/bin'
  sys.base_exec_prefix = '/usr/bin'
  sys.platlibdir = 'lib'
  sys.executable = '/usr/bin/python3.11'
  sys.prefix = '/usr/bin'
  sys.exec_prefix = '/usr/bin'
  sys.path = [
    '/home/veit/opt/Kratos/bin/Release',
    '/tmp/gidNHnM4p/UNNAMED.gid',
    '/usr/bin/lib/python311.zip',
    '/usr/bin/lib/python3.11',
    '/usr/bin/lib/python3.11/lib-dynload',
  ]
Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding
Python runtime state: core initialized
ModuleNotFoundError: No module named 'encodings'

I appreciate any help!

Sorry for the late answer. I don't know why I'm not getting GH notifications in the email and I did not see this one.

In my configuration I have it this way

Make sure that the python you set in the Python path box is the same python that you have used to buid the Kratos binaries

@jginternational That errors means that python is unable to find its libs folder where encoding and other libs are located. If Kratos can be launcher correctly from the terminal I suspect this is a problem on how GiD is manipulating the paths. Most likely:

'/usr/bin/lib/python311.zip',
'/usr/bin/lib/python3.11',

Those do not exist or are located in a different place.

@veiguf can you try to post the output of this python script?

import encodings as enc
print(enc.__file__)

Hi @jginternational and @roigcarlo, thanks for your answers.

@jginternational: yes python 3.11 is the version I used to build Kratos. FYI here the line in the config file
export PYTHON_EXECUTABLE=${PYTHON_EXECUTABLE:-"/usr/bin/python3.11"}

@roigcarlo: here the output of the script
/usr/lib/python3.11/encodings/__init__.py

The default for usr/bin/python3 as Python path is python3.12 where Kratos is not installed. Thus I think it is not an option.

That's the problem then, Gid is looking for the scripts /usr/bin/lib/ but they are located in /usr/lib/. @jginternational How can we tell gid to look into that location?
