Dipy dependence failure

[kerkelae]

Following the instructions (https://github.com/MIC-DKFZ/TractSeg/#install), I installed TractSeg and tried to run it, but could not because the current version of DiPy does not have the move_streamlines() function in dipy.tracking.utils. I tried to fix this by creating a new virtual environment without DiPy, but the installation of TractSect failed to download the required function from DiPy. This function is something that has been removed from the most recent release of DiPy. See below the error message I got after calling 'TractSeg' after installation.

Traceback (most recent call last):
File "/home/leevi/anaconda3/envs/tractseg/bin/TractSeg", line 38, in
from tractseg.libs import mrtrix
File "/home/leevi/anaconda3/envs/tractseg/lib/python3.7/site-packages/tractseg/libs/mrtrix.py", line 29, in

ImportError: cannot import name 'move_streamlines' from 'dipy.tracking.utils' (/home/leevi/anaconda3/envs/tractseg/lib/python3.7/site-packages/dipy/tracking/utils.py)

Is there something that I am missing?

I have the same problem. A workaround atm is to reinstall dipy at version 0.15.0: pip uninstall dipy; pip install dipy==0.15.0

Had the same problem. Thanks for the tip!

The newest master of TractSeg works with dipy 1.0. If you are using an older version of TractSeg you willl have to manually install dipy 0.15 or 0.16.
