ETA on Pyblish Lite GUI Update?

I would like to know if there is an ETA on the Pyblish Lite GUI update from PypeClub ?

Also, I would like to know where to direct issues regarding the GUI update.
I have some working Collection/Validation plugins for Pyblish Maya and Pyblish Lite.
However when I tried the updated PypeClub GUI my plugins did not show up at all.
Not sure about the reason.

Thanks.

Hi @virtualengineer, are you able to try and reproduce the problem with minimal plug-ins you can share? Sounds like we should better fix those before merging.

Hi @marcus ,

Sorry for the delayed reply.
I currently don’t have anything I can pass on (prod env).

In regards to PypeClub’s version of pyblish-lite,
I connected PyCharm to Maya 2018 via the MayaCharm plugin and ran the debugger to see whats up.

When I setup pyblish, an None Type exception is being triggered on pyblish-lite/control.py .

Here is my pyblish lite gui setup code. The exception triggers right on “import pyblish_lite”.
PYBLISH_GUI_LITE = r"pyblish_lite"

    # setup pyblish gui pyside2
    def setup_pyblish_lite():
        import pyblish.api
        pyblish.api.register_gui(PYBLISH_GUI_LITE)

        import pyblish_lite, pyblish_lite.settings
        
        # Customize the title of the window Pyblish-lite produces.
        # Default: "Pyblish"
        pyblish_lite.settings.WindowTitle = "Scene Validation"

        # Customize which tab to show initially from the existing tabs available;
        # "artist", "overview" and "terminal".
        # Default: "artist"
        pyblish_lite.settings.InitialTab = "overview"

        # Customize whether to use labels for plugins and instances.
        # Default: True
        pyblish_lite.settings.UseLabel = False

        # Custommize the width and height of the window
        pyblish_lite.settings.WindowSize = (500, 500)

I have attached a screen shot from the PyCharm debugger for reference.

I do not know if this problem is local only to my machine because of the environment or not.

Thanks @virtualengineer. At first glance, it looks like an issue with your Qt.py or Qt-binding install. It’s complaining about not being able to call QtCore.Signal(), which is native to Qt itself and unrelated to Pyblish or Lite.

I’m unfamiliar with PyCharm or it’s debugging mechanism, but it wouldn’t be the first time it’s the cause of error. Could you try this outside of PyCharm, or from within Maya? Also can you confirm this does not happen in the latest release, any only in this particular PR? (That would be odd!)

@marcus,

I have updated Qt.py to the latest version but I am still getting an error.
It very well may be a local pc environment issue.
I am going to do further testing to try to determine the cause.
Will get back to you later.

@marcus,

When I use default Pyblish packages, everything is fine.
When I switch to the branch update-from-pype and install that via pip, I get the error above.
I am thinking it may be a package issue.
I am not sure if I am installing this thing correctly.

Are there any dependencies ?
Is installing the pyblish lite pype update sufficient?
Or do I have to install other updated modules from pype’s git repos ?

To establish a baseline, what happens when you run this?

pip install git+https://github.com/pypeclub/pyblish-lite.git@update-from-pype
python -m pyblish_lite --debug

Due to the customized environment, the packages are in a non-standard location (other folder path).
I am having trouble getting the command to work. Sorry about that.

I can give you a pyblish setup script (which is triggering the error above with the update).
Perhaps you can try testing with it to see if there is an issue.
Environment: Windows 10, Maya 2018, Pyblish Lite “Pype Udpate”, Default Pyblish Maya.

@marcus,
By the way, there is a free open-source Community version of PyCharm from JetBrains.
PyCharm is one of the best Python IDE’s in my opinion.
Definitely worth including in your development pipeline.

pype.club fork of Pyblish-lite is dependent on this PR to pyblish-base https://github.com/pyblish/pyblish-base/pull/347

try pulling that for the test and see if it fixes it. In the PR we explain why that needed to be done even though pyblish itself supporting returning tracebacks. We couldn’t get them to work correctly in Maya (and I believe pyblish-qml has the same problem)

@mkolar
Thanks for the input.
I think I will wait until this feature is more mature before trying it out.
The new pyblish lite gui does look really promising. I will keep an eye on its development.
Keep up the good work!

@marcus, @mkolar
Hi,

It has been about a month since my last post on this topic.
I was wondering what your progress is like ?
Do you think this feature (pyblish gui upgrade) will get merged into the main project this year ?

Hi @virtualengineer, feel free to use the version in the PR directly, and report back with results. If all is well for you, then we’ve got one more reason to merge quickly. Because it’s a big change, I expect backwards compatibility to be affected, and it’s difficult to tell without having done enough testing, you can help with that.

pip install git+https://github.com/pypeclub/pyblish-lite.git@update-from-pype
