Facing the issue while trying to launch notebook.
Help is really appreciated :slight_smile:

Have you updated your environment yet :thinking:? Can you run the following and report back

git pull
conda env update
conda update --all

Yes I had done the updates.
Done it again just in case.
Still facing the same issue.

From google

Yesterday the tornado package just released version 5.0, and this new version may be causing this error. Try downgrading tornado to 4.5.3 and see if that fixes it.

try executing export PATH=~/anaconda3/bin:$PATH on the command line

That worked :slight_smile:
I guess till the issue gets resolved, there is a need to exclude tornado to update to version 5.
