'The following arguments were not expected: environment.yml --file create' when making new Mamba environment

Question

I need to test the model described in the IceNet paper but I am having issues making the Mamba environment.

After installing Mamba as described here, if I run the command mamba env create --name esports --file environment.yml I get the error The following arguments were not expected: environment.yml --file create Run with --help for more information.

Is there a way I can fix that? Also, I am working with an A100 GPU. Does it still make sense to use Mamba (the code was originally developed to run on a laptop) or am I already fine using Conda as usual?

Answer 1

Mamba should have the same API as Conda so the command yo tried should be correct. The error you get is likely due to a typo.

Note that I was able to trigger this exact error using Micromamba which has a different API than Mamba. Micromamba only has the micromamba create command that handles both YAML and list environment files. In that case, the correct command is:

micromamba create --name esports --file environment.yml
