IOPub message rate exceeded.
The notebook server will temporarily stop sending output
to the client in order to avoid crashing it.
To change this limit, set the config variable
`--NotebookApp.iopub_msg_rate_limit`.
Because the value of iopun_data_rate_limit is set very small.
Change the set value
jupyter notebook --NotebookApp.iopub_data_rate_limit=10000000000
It has been fixed in the latest version.
