ImportError: IPython version 6 is not supported.

Hello, when I pushed the "Deploy to Heroku" button and set a password, I got an Application Error after everything was done building. Here are the logs:

It seems that the cause is ImportError: IPython version 6 is not supported. How can I fix this?

IPython 6 was released a few days ago. The notebook store pgcontents needs to be updated. I opened an issue here: quantopian/pgcontents#28

IPython 6 is supported, now. Still a deployed noteboook does not run due to #38.
