Everything seems to go back to normal with the release of jupyter-client 6.1.0. Environment : Windows10, python 3.7.5, jupyter-client 6.1.0

I upgraded from Python 3.7.5 to Python 3.8.2 and now I see a new error. ``` c:\users\laure\appdata\local\programs\python\python38\lib\site-packages\pweave\__init__.py:51: SyntaxWarning: "is not" w ith a literal. Did you mean "!="? assert file...
