Error while installing object detection API: ImportError: cannot import name 'Cycler'

Question

Okay so this has been making me crazy, I am trying to set up the tensorflow object detection api, I have followed all the steps mentioned on the github page. However, on the last step when we need to check the installation by running:

python object_detection/builders/model_builder_test.py

This error shows up:

Traceback (most recent call last):
  File "object_detection/builders/model_builder_test.py", line 23, in <module>
    from object_detection.builders import model_builder

    from cycler import Cycler, cycler as ccycler
ImportError: cannot import name 'Cycler'

cycler is already installed but somehow its not able to import it. Can someone please help?

Thanks!

So the problem is fixed. I was using Anaconda and had created a separate virtual environment. The problem was that I had to extend my python path. I just exported the path of the site-packages and put it in to the bashrc and it all got fixed.
