Clean up imports

[tashrifbillah]

Hi @SenthilCaesar ,

All the scripts have redundant and repeated imports.

For example, see pipeline/dwi_masking.py:

import os.path
from os import path

Not only the duplication exists, but also the above block has been repeated. Similar repetition exists for other libraries as well.

To fix this, please create a new branch clean-imports from remove-ext-dep, and then make changes in the former. I shall review your changes and merge with remove-ext-dep. Please don't edit on remove-ext-dep branch.

Do the following:

# pull my latest changes
git pull origin remove-ext-dep
git checkout -b clean-imports
# correct the scripts
# commit your changes
git push -u origin clean-imports

More repetition:

cd src

(tf) [tb571@pnl-z840-2 src]$ grep -e "tensorflow" *py
compnet_axial.py:import tensorflow as tf
compnet_axial.py:import tensorflow as tf
compnet_coronal.py:import tensorflow as tf
compnet_coronal.py:import tensorflow as tf
compnet_sagittal.py:import tensorflow as tf
compnet_sagittal.py:import tensorflow as tf
