Please help for solving error in "evaluate test cases"

I got the following error when I execute the evaluate test cases,
can I go forward leaving this problem because it shows like input/output data rate exceeded.

"IOPub data 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

Current values:
NotebookApp.iopub_data_rate_limit=1000000.0 (bytes/sec)
NotebookApp.rate_limit_window=3.0 (secs)"
