Hi all,
Still working on my upgrade issue, but in the meantime, I have a question
about the sample data.
I'm trying the tutorial for source timec ourse visualization...
https://mne.tools/stable/auto_tutorials/source-modeling/plot_visualize_stc.html#sphx-glr-auto-tutorials-source-modeling-plot-visualize-stc-py
... but when I try
data_path = sample.data_path()
I get an error. It looks to me like it's looking for sample in my user
home directory, but I have mne installed in a shared directory. If I
understood better what the sample path should be, I could just create the
data path string. Or perhaps I don't have the sample data at all because
of the discrepancy between mne path and sample path?

Thanks for your help, see the error below.

hi Megan,

you can install mne anywhere you like but when it downloads
data it tries to put them in your home directory by default.

see doc: https://mne.tools/stable/generated/mne.datasets.sample.data_path.html

you can specify what path you want.

Adding to what Alex said, you can configure globally where you want datasets to be stored (and where MNE-Python will look for them when loading the datasets) using the MNE_DATA config variable. For example:

mne.set_config('MNE_DATA', '/opt/data')

will cause datasets to be downloaded to /opt/data/MNE-sample-data, /opt/data/MNE-fnirs-motor-data, etc.
