I don't get #Python package dependencies. I have two #conda envs with exactly python versions, packages all from #pip with major overlaps. Tried install another package in env A, after downgrading several packages including #pandas all went well. But when I try loading the newly installed package in REPL cmd, an error occurred complaining about pandas version. I removed the package, deactivate env A and activate env B, install same package in env B, same downgrade happened with pandas while this time all packages loaded without any issue. And this is not the first time I see this. Before this I use conda/mamba to manage packages and I switched to pip for package management hoping this won't happen anymore.
