Label frames issue

Hi, I’m having issues in label frames, after the frame extraction when I select " label frames" I got the error below:

Traceback (most recent call last):
File “/Users/pia/opt/anaconda3/lib/python3.7/site-packages/matplotlib/backends/”, line 784, in _onSize

how can I solve this?
Thank you

Looks like wxpython issue? What’s your os and do you run DLC froom GUI or prompt? If prompt, try in your conda env: python -m deeplabcut or for macs: pythonw -m deeplabcut . If there is an error again try: pip install -U wxPython==4.0.7.post2
