Unable to import local_bitwidth from Theano on google colab while importing shared_randomstreams.RandomStreams

  google-colaboratory, python, theano

I am having an issue to import 'local_bitwidth' from 'theano.configdefaults'. And the following message was displayed:

ImportError                               Traceback (most recent call last)

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

I received this error while I was trying to run this code first:

from theano import function
srng = RandomStreams(seed=234)
rv_u = srng.uniform((2,2))
rv_n = srng.normal((2,2))
f = function([], rv_u)
g = function([], rv_n, no_default_updates=True)    #Not updating rv_n.rng
nearly_zeros = function([], rv_u + rv_u - 2 * rv_u)

and after when I ran the convolutional neural network example from Michael Nielsen’s book where there is a line that calls the RandomStreams method. Both of them I ran on google collab, is there anyway to handle it on colab?
