Division by 0

[EmmaRenauld]

In the pytest of scil_dti_metrics:

RuntimeWarning: divide by zero encountered in log
D[..., 6] = -np.log(b0)

This originates from dipy/reconst/dti.py:2120, which is in method lower_triangular, which is called through our own line 215: tenfit = tenmodel.fit(data, mask)

Fun fact: debugging warnings can be made easier by making pytest crash on warnings, which makes the interpreter show the full traceback https://stackoverflow.com/a/59383021
