- MNE version: 1.3.1 - operating system: macOS 12.5.1 I am using this tutorial: [Overview of MEG/EEG analysis with MNE-Python — MNE 1.4.1 documentation](https://mne.tools/stable/auto_tutorials/intro/10_overview.html#sphx-glr-auto-tutorials-intro-10-overview-py) and when I do: sample\_data\_folder = mne.datasets.sample.data\_path() sample\_data\_raw\_file = ( sample\_data\_folder / “MEG” / “sample” / “sample\_audvis\_filt-0-40\_raw.fif” ) raw = mne.io.read\_raw\_fif(sample\_data\_raw\_file) it says: ModuleNotFoundError Traceback (most recent call last) Cell In[2], line 1 ----\> 1 sample\_data\_folder = mne.datasets.sample.data\_path() 2 sample\_data\_raw\_file = ( 3 sample\_data\_folder / “MEG” / “sample” / “sample\_audvis\_filt-0-40\_raw.fif” 4 ) 5 raw = mne.io.read\_raw\_fif(sample\_data\_raw\_file) File :12, in data\_path(path, force\_update, update\_path, download, verbose) File /lib/python3.11/site-packages/mne/datasets/sample/sample.py:14, in data\_path(path, force\_update, update\_path, download, verbose) 11 @verbose 12 def data\_path(path=None, force\_update=False, update\_path=True, 13 download=True, \*, verbose=None): # noqa: D103 —\> 14 return \_download\_mne\_dataset( 15 name=‘sample’, processor=‘untar’, path=path, 16 force\_update=force\_update, update\_path=update\_path, 17 download=download) File /lib/python3.11/site-packages/mne/datasets/utils.py:195, in \_download\_mne\_dataset(name, processor, path, force\_update, update\_path, download, accept) 192 def \_download\_mne\_dataset(name, processor, path, force\_update, 193 update\_path, download, accept=False): 194 “”“Aux function for downloading internal MNE datasets.”“” → 195 import pooch 196 from mne.datasets.\_fetch import fetch\_dataset 198 \_check\_in\_testing\_and\_raise(name, download) ModuleNotFoundError: No module named ‘pooch’ ​ what is happening? ---

Your Python environment is missing the `pooch` package. Depending on how you installed MNE-Python, you need to `pip install pooch` or `conda install pooch`. ---

I already did that and nothing changed.

Then you are probably not in the correct environment. In your script, can you please run `mne.sys_info()` and post the output here? ---

This output shows that you don’t have `pooch` (and many other packages) installed. Are you intentionally running MNE-Python on Pyodide (AFAIK we don’t officially support it)? You need to install the packages inside the correct environment, in your previous post you seem to have installed `pooch` in another (conda) env.
