There was a time, when conda was the best package manager our there!
However more and more the “found conflicts! Looking for incomatible packages. This can take several minutes” (hours actually) and all the time spent watching “solving environment” completely tarnished the usability of conda as the package manager.
pip becomes soo much easy to use
shame really
This is a bigger discussion that probably shouldn’t happen here, but to your specific problem: you will find that you have the best experience with conda if you pin or bound some of the versions that you allow in an environment. That’s probably good general practice - but of course you might want to find and fix out what the “incompatibilities” are that you are suffering from.
Note, aside, that the conda project is working to incorporate the libmamba solver, which has a reputation of being faster but otherwise feature-complete.
