Hi @murray, sorry about that - with the Jupyter notebooks that do training while displaying the camera on Nano 2GB, we recommend to use USB camera (such as Logitech C270 or C920) to avoid the camera freezing during training.

You can also do training with the Hello AI World tutorial, which doesn’t display camera while training. That works fine with MIPI CSI camera on Nano 2GB. There are also some instructions for decreasing RAM usage included with that tutorial:
