Q:

Trouble running sumo flow demo example

Repost from user Jin G.

After going through the Flow installation tutorial I tried to run the sumo demo example using the following terminal command:
python examples/sumo/sugiyama.py
I got the following error message: Could not connect to TraCI server at localhost: 40335 [Errno 111] Connection refused
Any thoughts on what to do to fix this issue? 

A:

After days of retrying and searching I found a fix..
My issue was that I did not activate the conda environment when running the simulations. 
To do so before running any simulations type the following into the command prompt:
source activate flow
