When I tried to install the MNE, I did not get the package running. I tried to make a new environment for MNE. However, it gives me an empty environment. Could you please help me here? By the way, I am following this link:

Hi @pronob,
could you explain in more detail what went wrong - what commands did you use and what deviated from your expectations? Did something happen when creating the environment - an error message maybe? Why do you think the environment is empty?
I am using these lines of code:
curl --remote-name https://raw.githubusercontent.com/mne-tools/mne-python/main/server_environment.yml
conda create --name=mne --file=server_environment.yml
It gives an environment without any error. However, when I used conda activate mne it provides an error.
what error do you get?
Alex
Now, it gives an error do not even create an environment. The error is CondaValueError: could not parse ‘name: base’ in: server_environment.yml
Could you please post all the output from the terminal?
(mne) D:>mne sys_info

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

Original error was: No module named ‘numpy.core._multiarray_umath’
Try “conda env create” instead of “conda create” ?
The other error:
This might be happening because of the incompatible python and numpy versions. I am not sure how your python version is Python3.9 here instead of 3.8 as per the server_environment.yml file. I think you should remove the environment with “conda env remove -n mne” and then create a new one again with “conda env create --name=mne --file=server_environment.yml”.
Hi @pronob
I had the numpy error you post yesterday when setting up an mne environement. At one point (when resolving some issues with spyder) some of my packages were updated to the normal conda channel from conda-forge and this seems to have led to some binary incompatibilities.
You can try updating numpy and other packages to the version from conda-forge and see if that fixes your problem:
conda upgrade -c conda-forge --all
