Error opening Extensions Manager and loading previous developed Modules

Hey all,

I’ve been using 3D Slicer for a while but I had to install it on a different machine and it’s giving some errors right after the installation.

When I open Extensions Manager this error is printed:

[Qt] An OpenGL Core Profile was requested, but it is not supported on the current platform. Falling back to a non-Core profile. Note that this might cause rendering issues.

And then I tried loading a Loadable Module I’m developing (through Extension Wizard > Select Extension) and it gave this error:

[Python] The module factory manager reported an error. One or more of the requested module(s) and/or dependencies thereof may not have been loaded.

I can create a new Extension and Module but it doesn’t load when Slicer is restarted.

Edit: I’m using Slicer 5.2.1 on Windows 10

If the extension manager window comes up normally then the warnings can all be ignored.

The module import issue appears to be due to a missing OpenCV package. Running pip_install("opencv-python") should fix it.

To avoid this in the future, the module could could be updated with something like this:

try:
  import cv2
except ModuleNotFoundError:
  pip_install("opencv-python")
  import cv2

Thank you for the reply!

It seems to be working fine. Is there some way to supress the warnings?

Most of those warnings are because the extensions list http links to their screenshots but the newer Qt versions require https since the extension page is hosted via https. Ideally extension providers should sort these out but it may take a while. For now it’s easier to ignore them.
