ModuleNotFoundError: No module named 'bertopic'

[entelecheia1963]

When I run the first line from the quick start guide:

from bertopic import BERTopic

I get:

ModuleNotFoundError: No module named 'bertopic'

Despite the fact that I have installed it using Mamba and it appears on the 'mamba list' output (full list below).

From within Jupyter, If I run

!conda info

in a cell, I get:

And when I:

print (sys.executable)

I get

Any ideas for fixes would be much appreciated!

OK! I think I solved me own problem - and I will leave it here for reference.

I used clues from this stackoverflow post: https://stackoverflow.com/questions/39604271/conda-environments-not-showing-up-in-jupyter-notebook

I did this:

source activate myenv
pip install ipykernel
python -m ipykernel install --user --name myenv --display-name "Python (myenv)"

So that I can now explicitely select the correct environment from within Jupyter notebooks .. If I do that, and run the import it appears to work (with some warnings .. )
