The new Form feature in Google Colaboratory

Question

Can someone explain or give a notebook example how to use the new Form feature? It looks really exciting, but I cannot find any example or even an announcement anyw

Answer 1

It's a useful and simple features to input values in Colab notebooks, still not described in Colab documentation.

For example I have a notebook to run instance segmentation of an image. To specify image url, before I had to modify a python variable like this:

image_url = 'http://example.com/image.jpg'

Now I can make a user friendly form field ("+field" button) with values:

• Variable name = image_url
• Variable type = string
• Form field type = input

Then switch to form visualization (dropdown near "+field" button) to visualize only form during notebook execution.
