Hey,

When I try to run python main.py from examples, I get the following error. How may I solve this?
Thanks in advance.

Sorry, ChainerRL Visualizer is not tested on Windows. Multiprocessing in python sometimes does not work well on Windows.

So any way to work around it to solve this issue , I have the same problem with my selenium script
