Error in notebook 11

[adazi]

In notebook 11, the line
tf.set_random_seed(seed)
is deprecated and generates and error:
AttributeError: module 'tensorflow' has no attribute 'set_random_seed'

Apparently set_random_seed() has been replaced with random.set_seed(). The problem can be fixed by replacing that line with
tf.random.set_seed(seed)
