IOPub data rate exceeded.

How do I rectify this in Google Colab?

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_data_rate_limit.

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

Colab bundles featuretools 0.4.1 presently, and I suspect you're using newer APIs. I'd start by upgrading the featuretools library like so:
!pip install -U featuretools

After that, you'll need to restart your Python process using the Runtime -> Restart menu.

import featurestools
