Hello, I solved the problem,
solution:
conda create --name=mne python=3.7
instead of
conda create --name=mne --channel=conda-forge mne
then installed successfully：D
@CliffordTHU this does not solve the problem unfortunatelly. This way you install an environment called mne that contains only python, but not the mne package.
Could you say what exactly happens when you try to install the 3d mne environment? Below that comment you pasted an example of trying to update conda package of the base environment and it wasn’t updated because in your case it is up to date. But your earlier examples of installing mne looked as if they were either not copied in full or the installation process was terminated.
Also - check if you antivirus does not complain during the installation. I just had an installation stuck for about 30 minutes, because I didn’t notice that my antivirus “blocked a threat”, which was one of the installation components (a false alarm), after adding it to exceptions list the installation progressed.
Hello, sorry for didn’t reply 2 days, I thaught I accomplished the problem, however,
when debug,
it comes to:
somehow it can’t import surfer
yes, I used this command to create a environment called mne, then download all packages it needs, I thaught this works
when I installed 3d part by
conda create --name=mne --channel=conda-forge mne
sometimes it went with
(py37) [root@xxx~]# conda create --name=mne --channel=conda-forge mne
Collecting package metadata (current_repodata.json): done
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.
Collecting package metadata (repodata.json): done
sometimes it stucked at the last step.
Now I always get an error called: couldn’t build the shadow program for solving msaa
I have no idea what this means, may you help with this?
here’s the code:
(mne) [root@xxx]# python -c "import mne; mne.sys_info()"

MNE-Python 0.24+ no longer uses PySurfer, you must be on an old unsupported version. You should use the mne.viz.Brain class instead nowadays
Also, it looks like you might be on a headless display/system, consider setting up Xvfb for rendering capabilities. See Advanced setup — MNE 1.6.0 documentation for example
