ImportError: No module named past.utils about eman2

I find that an activate file is under the ~/EMAN2/bin folder.
So I run source ~/EMAN2/bin/activate to activate this environment. But it failed.

Here's the output:

An unexpected error has occurred. Conda has prepared the above report.
If submitted, this report will be used by core maintainers to improve
future releases of conda.
Would you like conda to send this report to the core maintainers?
[y/N]: y
Upload successful.

Thank you for helping to improve conda.
Opt-in to always sending reports (and not see this message again)
by running

    $ conda config --set report_errors true

So this means that the installation progress was failed.

What should I do now?

Thank you!

It looks like you have activated multiple environments on top of each other: cell, base and pytorch. And, you have two different anaconda installations in PATH: EMAN2 and anaconda3. EMAN2 installation should be the only installation in PATH for it to work. It should, also, be possible to activate the EMAN2 installation through the main anaconda installation, but that would require some advanced conda/anaconda knowledge which would be challenging for us to properly document in the EMAN2 wiki.
