Import error for nipype.interfaces.dipy.base #3411
Description
Summary
import nipype.interfaces.dipy generates an error for me, with Python 3.9 and 3.8, Dipy 4.12 (latest release) and latest release or current master of nipype.
Actual behavior
Running the above import generates the error TypeError: 'NoneType' object is not iterable generated from dipy_to_nipype_interface at:
nipype/nipype/interfaces/dipy/base.py
Line 200 in f756b71
This function is executed during import in
interfaces.dipy.preprocess. It seems this works correctly for several workflows (LabelsBundles, MedianOtsu, RecoBundles, LocalFiberTrackingPAM, PFTrackingPAM) but crashes for GibbsRingingFlow because default_values is None. How to replicate the behavior
- create a fresh venv
- pip install the latest dipy and nipype packages
- open python and run
import nipype.interfaces.dipy
Expected behavior
A working import. This seems an easy fix, if others can reproduce the issue I would be happy to make a PR replacing
nipype/nipype/interfaces/dipy/base.py
