Description of expected behavior and the observed behavior

I am new to holoviews and trying to import the module in a jupyter lab notebook. I get the list of modules above directly inside the jupyter lab notebook using "!pip list " in the previous cell. Then I try to "import holoviews as hv" (after importing pandas and numpy) but I get the error message :

ModuleNotFoundError: No module named 'holoviews'

My guess would be that you are in the wrong environment. Are you using conda or venv?

Yes, i am using conda environments. I checked that I launched jupyter lab in the correct environment. Moreover, i used !pip list directly in jupyter lab to double check if the holoviews was there as well (my understanding is that !pip list would show me only the currently available modules)

Try writing !conda info and !conda list in the notebook and paste them here.

My company has a strict firewall and we are using an internal repository copy for modules. I am using pip only for the modules, not conda. Here are the outputs :

At a glance, I don't see any problems. My suggestions would be:

• Check if you are using the right ipykernel this should be the one in the environment:
• Try to install ipykernel (if it is not already installed)
• Try to reinstall holoviews.
• Remove any folder named holoviews in the folder.
