Hey @Chumei_Tang,
Thanks for following up and reporting. It appears that this is an issue related to setuptools (this is a deprecated package that has been fully removed in our current development cycle). This isn't something I've seen before, but let's see if a re-install fixes the issue. Try running the following:
conda install --force-reinstall setuptools
This should hopefully resolve these annoying messages, but I'd test out a few commands after completing this just to confirm.
Cheers
