- MNE version:1.3.1 - operating system: Ubuntu 22.04 Recently went to run my code and got the following error message. This happens with just a single line of code `import mne ` ```python KeyError Traceback (most recent call last) File ~/anaconda3/envs/jupyterEnv/lib/python3.10/site-packages/mne/utils/docs.py:3412, in fill_doc(f) 3411 try: -> 3412 f. __doc__ = docstring % indented 3413 except (TypeError, ValueError, KeyError) as exp: KeyError: 'stc_true_metric' During handling of the above exception, another exception occurred: RuntimeError Traceback (most recent call last) /home/roy/Desktop/github/Graph_Inference/Graph_inference/notebooks/7.0-analyze-alphaOverdelta.ipynb Cell 2 in () 1 # print mne version ----> 2 import mne 3 print(mne. __version__ ) File ~/anaconda3/envs/jupyterEnv/lib/python3.10/site-packages/mne/ __init__.py:120, in 118 from . import minimum_norm 119 from . import preprocessing --> 120 from . import simulation 121 from . import stats 122 from . import surface File ~/anaconda3/envs/jupyterEnv/lib/python3.10/site-packages/mne/simulation/ __init__.py:7, in ... 3417 % (funcname, str(exp))) 3418 return f RuntimeError: Error documenting cosine_score: 'stc_true_metric' ``` ---

Hello, I can not reproduce if I install the version 1.3.1 in a fresh environment. I suggest you try to setup a new environment and install the latest version. Mathieu ---

Hello , Even I was getting the same error with MNE version 1.4. I use Windows 10 as my OS. I had to uninstall Conda and all its environments. I downloaded Anaconda again, as always, and tried to use: > conda install --channel=conda-forge --name=base mamba > mamba create --override-channels --channel=conda-forge --name=mne mne but I get the error no environment named ‘mne’ present. Though the execution was complete. Also, the MNE standalone installer link for Windows does not work. I am not sure what is wrong. ---

But, I am facing some issues: - ICA\_plot\_components renders only the first plot window opens after which the code hangs unless keyboard interrupted, something similar to this [ICA plot\_components opens figure one by one (and might hang depending on the console) · Issue #11693 · mne-tools/mne-python · GitHub](https://github.com/mne-tools/mne-python/issues/11693). I had to change the source code when I was using the MNE downloaded by Conda which resolved the issue. I am facing this again. - I am trying to calculate the BEM but this is what I get: > …inner skull (2562) → inner skull (2562) … > Inverting the coefficient matrix (homog)… > Modify the original solution to incorporate IP approach… > Combining… > Windows fatal exception: code 0xWindows fatal exception: code 0xc06d007f > Thread 0x00005114c06d007f > (most recent call first): > File “C:\MNE\lib\site-packages\ipykernel\parentpoller.py”, line 93 in run > File “C:\MNE\lib\threading.py”, line 1016 in \_bootstrap\_inner > File “C:\MNE\lib\threading.py”, line 973 in \_bootstrap > Main thread: > Thread 0x000008cc (most recent call first): > File “\< **array\_function** internals\>”, line 5 in dot > File “C:\MNE\lib\site-packages\mne\bem.py”, line 303 in \_fwd\_bem\_ip\_modify\_solution > File “C:\MNE\lib\site-packages\mne\bem.py”, line 352 in \_fwd\_bem\_linear\_collocation\_solution > File “C:\MNE\lib\site-packages\mne\bem.py”, line 452 in make\_bem\_solution > File “”, line 12 in make\_bem\_solution > File “…”, line 151 in > File “C:\MNE\lib\site-packages\spyder\_kernels\py3compat.py”, line 356 in compat\_exec > File “C:\MNE\lib\site-packages\spyder\_kernels\customize\spydercustomize.py”, line 473 in exec\_code > File “C:\MNE\lib\site-packages\spyder\_kernels\customize\spydercustomize.py”, line 740 in \_exec\_cell > File “C:\MNE\lib\site-packages\spyder\_kernels\customize\spydercustomize.py”, line 689 in runcell > File “~AppData\Local\Temp\ipykernel\_19284\2644504182.py”, line 1 in > Restarting kernel… I had faced the same issue when I used the MNE installer previously. This was resolved when I switched to the Conda route for downloading MNE. I am facing the same problem again. I cannot download MNE using Conda as mentioned previously. I am not sure what is wrong. P.S- I do not have a core background in coding! there might be some trivial issues which I am missing. Thanks! ---

For the ICA part, it is fixed in `main` and it will be fixed in the next minor release, 1.4.1. You could try to install the main version with `pip install git+https://github.com/mne-tools/mne-python`.
