Solution to issue cannot be found in the documentation.

I checked the documentation.

Issue

After fresh installation of mambaforge for Linux x86_64 and running mamba update --all -y, I get the following error when try to run mamba env <what ever command>, e.g., for mamba env --help (though conda env --help works just fine):

'Namespace' object has no attribute 'func'

An unexpected error has occurred. Conda has prepared the above report.
If you suspect this error is being caused by a malfunctioning plugin,
consider using the --no-plugins option to turn off plugins.

Example: conda --no-plugins install <package>

Alternatively, you can set the CONDA_NO_PLUGINS environment variable on
the command line to run the command without plugins enabled.

Example: CONDA_NO_PLUGINS=true conda install <package>

Looks like an incompatibility with the new conda 23.7.x series and the current mamba. You might need to report this to mamba-org/mamba.

The installation itself worked before the update, right?

breengles · 2023-07-28T15:12:24Z

Hi @jaimergp!
Yep, the installation worked just fine. I think the issue appeared today (or quite recently as I think).
I will open an issue there and mention this one

jtabox · 2023-08-03T01:22:12Z

Can confirm, have had fully working installation but updated everything today and since then I'm getting the exact same error.

mikofski · 2023-08-05T00:04:43Z

Interesting, so I used mamba to downgrade conda to 23.5.2 and now it works again. Can you please let us know when it's working again? thanks!

BTW: since downgrading conda, now in any env other than base, I get this after any command:

Could not load conda plugin `conda-build`:

argument of type 'NoneType' is not iterable

but my base env does have conda-build version-23.5.2, same as conda. Weird

jaimergp · 2023-08-06T12:40:37Z

The PR in mamba-org/mamba has been merged, so it's a matter of waiting for a new release on their end.

corneliusroemer · 2023-08-06T20:19:52Z

Thanks for reporting and figuring out a workaround. To make it more findable, I've made a Stackoverflow Q&A: https://stackoverflow.com/questions/76847652/mamba-env-throws-attributeerror-namespace-object-has-no-attribute-func/76847653#76847653

shermansiu · 2023-08-16T08:13:41Z

I didn't want to wait, so I applied Jaime's bug fix to my local copy of mamba.py... Took me about 2 minutes. 😅

shermansiu · 2023-08-19T12:43:11Z

The relevant issue on Mamba's end is mamba-org/mamba#2715. Finding that issue is harder on Google compared to this issue as of this moment (which is now the first search result), so I'm including it here for convenience's sake. (...Which I suppose was also linked in the StackOverFlow post)

mfisher87 · 2023-08-20T20:22:49Z

Just ran in to this. Worth noting that while the issue on mamba-org is closed, the fix has not yet been released. The current latest version 1.4.9, released over a month ago, is impacted!

EDIT: Wanted to stress that with "released over a month ago", I only mean "the latest version is impacted because it occurred before this fix, not because the problem has regressed". I realized it kind of comes off as "jeez, release already!" :) ❤️

shermansiu · 2023-08-24T10:37:34Z

Thanks to Cornelius, we just got a new release of mamba 3 hours ago. The fix is out in mamba version 1.5.0!

(Feel free to close this issue).

jaimergp · 2023-08-24T12:11:28Z

Noice! I'll close. Feel free to comment / reopen if you experience any issues with the fix!
