ImportError: Cannot load backend 'TkAgg' which requires the 'tk' interactive framework, as 'headless' is currently running

[vetmohit89]

I am trying to run segmenter with the following command
python segmenter.py -s data.tsv -ku -j 100 > signals_stall_segments.tsv

It is giving following error.

Traceback (most recent call last):
File "segmenter.py", line 4, in
import matplotlib.pyplot as plt
File "/home/mbansal/.conda/envs/mlpy/lib/python3.6/site-packages/matplotlib/pyplot.py", line 2336, in

ImportError: Cannot load backend 'TkAgg' which requires the 'tk' interactive framework, as 'headless' is currently running

Hello,
This is probably because you don't have tkinter installed.

You can either try installing that, or try these 2 solutions.

1. comment out line 3 in segmenter.py
   #matplotlib.use('TkAgg')
2. change line 3 in segmenter.py to
   matplotlib.use('Agg')

I hope this helps
