Error starting AI2THOR Env

[kaushikb258]

Unable to start an Env. I tried this:
python random_walk.py

/home/kb/anaconda3/lib/python3.6/site-packages/ai2thor/controller.py:1152: UserWarning: start method depreciated. The server started when the Controller was initialized.

We made this repo with ai2thor version 0.0.44, a lot has changed with the later versions of ai2thor. Let me know if it works with 0.0.44 or otherwise it might be worth your time trying newer versions like robothor and manipulathor.
