Issue with typing.AscyncGenerator for python 3.6.0 about nbclient

[davidbrochart]

Hi @esvhd, thanks for opening an issue. I can reproduce the bug, but unfortunately fixing it in nbclient won't be enough since prompt-toolkit also has the issue, and they require python>=3.6.1 for that reason. Out of curiosity, what version of prompt-toolkit do you have?

Hi @davidbrochart , thanks for taking the time to look at this. I'm using prompt-toolkit 2.0.4 in this environment.

I see, I think they didn't have type checking yet in this version, so I guess that a fix in nbclient would work for you. Unfortunately I couldn't find a nice way to ignore the AsyncGenerator return type of async_setup_kernel depending on the python version.
#119 just removes the type. On the other hand, I'm not sure having this return type is of great value. So if nobody has an objection, I will go ahead and merge it.

Thanks!

We can either merge #119 which removes type checking for the return value of async_setup_kernel, or require python>=3.6.1 instead of currently python>=3.6.
Thoughts?

I'd prefer we require python >= 3.6.1

Same. 3.6.0 will also have outstanding security issues...

Sorry @esvhd, we won't support python 3.6.0 anymore.
