No module named pyblish_qml

[monsteradurm]

Receiving the error "No module named pyblish_qml" when attempting to exec pyblish_maya.show() under maya 2018.

executing:

import pyblish_qml, pyblish, pyblish_maya
from pyblish_qml import api

sys.path.append(r'G:\_PIPELINE_MANAGEMENT\_externalPythonLibraries\pyblish_maya\pythonpath')

pyblish.api.register_gui("pyblish_qml")
api.register_python_executable("C:/Python27/python.exe")
api.register_pyqt5(r'G:\_PIPELINE_MANAGEMENT\_externalPythonLibraries\PyQt5')

pyblish_maya.setup()
pyblish_maya.show()

result:

pyblish: Deregistered g:/_PIPELINE_MANAGEMENT/_externalPythonLibraries\pyblish_maya\plugins
pyblish: Integration torn down successfully
pyblish: Registered g:/_PIPELINE_MANAGEMENT/_externalPythonLibraries\pyblish_maya\plugins

Make sure pyblish_qml is on your PYTHONPATH environment variable, that's the one getting passed to your Python executable (not sys.path, which is only used by Maya).

import os
...
os.environ["PYTHONPATH"] += os.pathsep + os.sep.join(pyblish_qml.__file__.rsplit(os.sep)[:-2])
...
pyblish_maya.show()

If you know where pyblish_qml is, best to add the path directly instead of the .rsplit mess above.

These can also be added to your environment prior to launching Maya.

# On Windows
$ set PATH=%PATH%;c:\python27
$ set PYTHONPATH=c:\pythonpath
$ maya

Let me know if this works for you.

This fixes the original issue, though I am receiving a dialog stating

"This application failed to start because it could not find or locate the Qt platform plugin "Windows" in "".

[mottosso]

Make sure your PyQt5 installation works with that Python version.

Thanks.
Getting closer..

I am getting yet another error though:

I have followed the advice/instructions here but havent been able to resolve the issue.
pyblish/pyblish-qml#215

executing:

pyblish_maya.setup()

Thanks for sharing what you tried, but which advice did you follow exactly? Installing via pip3 or installing via Git?

It looks like your version of PyQt5 is too old; this should work.

[monsteradurm]

Using the git install resolves the issue within pyblish_maya, but stops my pyblish_nuke from working..
Perhaps I need to be using separate PyQt installs for different versions.
