There's a line in our pythonrc.py file that checks if it's a UI session or not. Basically:


For most computers this works fine. For some though, it gives the following error:


I can't figure out what could be causing this, or even what to do to diagnose it. Other calls to the ‘hou’ module like ‘hou.isApprentice()’ work fine.

Has anyone run into this problem or have a work around?

Thanks!

That's really odd. Could you try to print and see where hou is loaded from ?

try:
    import hou

    print(hasattr(hou, 'isUIAvailable'))
except ImportError:
    print("Failed to import hou") 

Thanks for the response! Sorry for the late reply, I haven't had access to the affected machine in a while.

It gets more strange… Your code returns this:

So it seems to know the module exists that way, but still fails with something as simple as:

I'm trying some things now. May have to find some sort of work around. It could also just be a problem with the current version we're on (16.5.439). I'll post back here if I find out anything.

It looks like you've got a few spelling errors in the code being run which would give the observed AttributeError exceptions:

Correct:

isUIAvailable

Incorrect:

isUIAvaliable
isUIAvailabe

Ha! Embarrassing… I bet I wrote it wrong once or twice when I was debugging. Thanks for looking into it grahm and jjayakumar.
