Jupyter notebook: No module named 'notebook.base'

Question

I'm trying to create a simple HTML version of a notebook without the code.

jupyter nbconvert "HFB data dashboard.ipynb" --to html --no-input

But it returns:

line 18, in <module>
    from notebook.base.handlers import APIHandler, IPythonHandler
ModuleNotFoundError: No module named 'notebook.base'

I'm using notebook version 7.1
