Yao Yao on March 4, 2019

1. Cannot connect to kernel

Jupyter notebook: No connection to server because websocket connection fails:

Uninstall tornado 6 and reinstall tornado 5.

sudo pip3 uninstall tornado
sudo pip3 install tornado==5.1.1

2. Ugly fonts

Install jupyterthemes:

pip install jupyterthemes

My current setting is:

jt -t grade3 -f source -fs 9 -ofs 8 -T -N -kl
