Trying to install a Logitech C270 usb camera following instructions. Jupyterlab errors in usbcamera.ipynb with
"“Error creating widget: could not find model”
I can’t find a way to upload a screen shot or copy/paste the code but its in the notebook cell called “#Create a widget to view an image stream”. Nothing works beyond this point and I assume there is little point moving on with the course without a functional camera?
