environment_cpu.yaml does not exist (perhaps a typo or a missing channel

[cdalinghaus]

The install instructions as per readme never worked for me:

mamba create -f <ENV>.yaml -n <ENV_NAME>

results in

Looking for: ['environment_cpu.yaml']
(...)
The following package could not be installed
└─ environment_cpu.yaml   does not exist (perhaps a typo or a missing channel

The solution to this is to use the update command instead
mamba env update -n <your-env> --file environment_cpu.yaml

Source: mamba-org/mamba#633

In case somebody else is facing the same issue.

Hi @cdalinghaus,

Could you try using mamba env create -f environment_cpu.yaml to install the environment?

(this creates an environment with name torch-em-cpu by default - unless you specify using -n <ENV_NAME>)

[cdalinghaus]

Thanks @anwai98 .

I further tested it and it seems to work when I use
mamba env create -f environment_cpu.yaml

But when I use it without the env, as the readme suggests it does not work:

mamba create -f environment_cpu.yaml -n test

Looking for: ['environment_cpu.yaml']

This is a typo in the readme, thanks for noticing @cdalinghaus . Both mamba and conda require the env in the command for creating environments from a file. I updated it.
