Hello all: As title suggests, my company is > 200 employees. Therefore, according to new Anaconda TOS, there is a $50USD/machine applied if default conda channels are used. However, my company has taken decision to eliminate the use of Anaconda platform and its services completely across the entire company. Even the website is blocked and I cannot access the documentation/help files.

When using pandas.read_excel() I get the following error:

I created a new python=3.12 environment using anaconda.

I have a backup from my anaconda navigator environment on mac but when I’m importing it on windows its not working and showing the error that packages not found:

When I used conda install -n base conda-libmamba-solver
conda config –set solver libmamba
These two commands to install and set the new solver，i thought everything was fine.But when I try to install e.g. numpy package, I got the error CondaValueError: You have chosen a non-default solver backend (libmamba) but it was not recognized. Choose one of: classic

I’m trying to get a more practical grip on data science with Python and thought it would be a good idea to follow a tutorial (hoping to avoid doing lots of troubleshooting). However, I didn’t get very far until the mess started.
