fMRIPrep / ModuleNotFoundError: No module named

fmriprep

Hi all,

We are starting to see that the numbers of people encountering the ModuleNotFoundError are on the rise. Typically, this is the error you’d get:

'Traceback (most recent call last):

ModuleNotFoundError: No module named 'fmriprep.interfaces.images''

The most likely reason for this is that you are reusing a work directory containing cached results that were obtained with a previous fMRIPrep version.

There are only two solutions to this problem: 1) use the same version you used originally; and 2) wipe out the work directory (or use a new path for it).

This error may occur regardless you are using containers or not.

Just to add: unless you were using a veeery old version of fMRIPrep, you should be able to keep your FreeSurfer results.
