ModuleNotFoundError: No module named 'pynq'

[Mengzou01]

Hello everyone!
I started my first finn project with an example in the JupyterNotebook named "cnv_end2end_example". I successfully finished the design in the docker/Ubuntu22.04 and get the "deploy-on-pynq-cnv.zip" download into my PYNQ-Z2 board., but encoutered an error like "ModuleNotFoundError: No module named 'pynq'", I wonder if someone can help me.
