霸气的烈马
1 月前
I am using DLC for the first time.
Here’s some set up info:
I installed it with the conda environment, on a windows 11 machine, with a nvidia quadro p400 gpu.

deeplabcut = 2.3.5
napari-deeplabcut = 0.2.0
Cuda compilation tools, release 10.1, V10.1.105
tensorflow = 2.10.0
PyQt5 = 5.15.7
PySide6 = 6.3.1
vispy = 0.12.2

I had to edit the .yaml as suggested here to make it work.

Now, about my issue:
I am using the GUI. I am trying to test it with some video I have of a mouse on a threadmill. The video is in .mp4 format, that i converted from .mj2 using ffmpeg. I successfully extracted frames from the video
When I move on to labelling, the napari GUI is displaying only black, empty images. I can’t toggle layer visibility, yet I can see from the thumbnail that the image is supposedly here.

image 1248×692 33.1 KB

Here’s the error report I get

There seems to be something wrong with vispy and opengl …

vispy does not see opengl

Yet pip instal opengl results to this :


Requirement already satisfied: pyopengl in c:\users\jcspm\anaconda3\envs\deeplabcut\lib\site-packages (3.1.7)


I have tried a solution I found on this thread, but it did not work.

I am at a loss, and suffered already during the installation process :sweat_smile: so I would greatly appreciate any help.


Thank you

Julien


Hi Julien,


Have you tried the solution described in this thread?


It seems that PyQt5 is being used when it should be Pyside6.


Best,

Niels

I uninstalled pyside6 and it broke DLC


Loading DLC 2.3.5...

    import PySide6.QtWidgets as QtWidgets

I installed qtwidgets on its own and it did not change anything


Thank you

              
Sorry I think I was misunderstood - it’s PyQT5 that should be uninstalled, as DeepLabCut requires PySide6 to be used.


You can run:


pip uninstall PyQt5
pip install pyside6<6.3.2
              
I tried that and got the exact same error


RuntimeError: Using glBindFramebuffer with no OpenGL context.

While vispy keeps not seeing opengl
