[Startup] RuntimeError: This event loop is already running

Not sure how to submit this correctly, but I thought it might be nice to report my error since the program kinda doesn't work. OS: Windows 7 (64bit) Python: 3.6.1 (64bit)

[BenRussert]

I did some googling just now and found some people saying they fixed something similar by upgrading ipykernel. Can you try this?

[shekeru]

i think i tried that and i ended up with a different error finally downgrading back to tornado 4.5.x fixed it lol

[BenRussert]

Glad you fixed it!
