Doesn't work with Nuke

[mottosso]

As reported by Jakub over in the chat, there's something preventing Pyblish QML from working with Nuke.

import os
for key, value in os.environ.items():
    if "PYBLISH_QML_PYTHON_EXECUTABLE" in key:
        print(key,value)
# Result: ('PYBLISH_QML_PYTHON_EXECUTABLE', 'C:\\Users\\Public\\avalon_env\\python.exe')

Traceback (most recent call last):

for key, value in os.environ.items():
    if "PYBLISH_QML_PYQT5" in key:
        print(key,value)
# Result: ('PYBLISH_QML_PYQT5', 'C:\\Users\\Public\\avalon_env\\Lib\\site-packages\\PyQt5')

Tests:

• Nuke fully licenced didnt work for the same reason > ImportError: DLL load failed:... so non-commertial wasn't an issue..
• vanilla Python3.6.5, PyQt5==5.7.1 - didnt work and the error is the same as from conda env.. ^
• vanilla Python2.7.15, python-qt - started but the window didnt load fully and perhaps crashed internally. No logging so don't really know what happened..

I presume it is some Nuke's internal incompatibility issue with outside python3 PyQt5 but that is just a guess.

What Nuke version? I've opened the Pyblish QML GUI in Nuke no problem in Linux in the past.

[jakubjezek001]

Hi @darkvertex thanks for question. Its windows 11.2v3. Would you mind to share your config?

[darkvertex]

It's studio stuff using Rez packages that I can't really share, sorry, but it should be possible to accomplish a working pyblish-qml with a conda environment with only Python 2.7, PyQt5, pyblish-base and pyblish-qml and using the PYBLISH_QML_PYTHON_EXECUTABLE env var in Nuke to point to this environment before you use or import the GUI.

It can be a shellscript/.bat that sets the good environment and passes the args straight to the python executable, it doesn't necessarily have to be a path to python.exe itself.

@jezscha Have you experienced the issue on a different computer or user? Could it be something pre-existing in your particular environment? E.g. multiple Qt installs?

[jakubjezek001]

@darkvertex I understand. But anyway thanks for the comprehension. In our setting we wish to stick to Python3.6.5, PyQt5==5.7.1 for all integrations if it would be possible. I understand Pyblish-qml in Nuke can be accomplished in Python2.7 and I have already experienced it myself.

@mottosso I have been testing it on two machines which one of them was vanilla and no paths existed in env-vars. Also the second has been cleaned from all traces in env-vars and files and register. I am going to test it on other tomorrow so lets see.

@jezscha were you able to make progress with this the way you wanted?
