`IllegalStateException` when using `from`...`import`

[tatianacv]

For the following example:

from tensorflow import random

def add(a, b):
  return a + b

c = add(random.uniform([1, 2]), random.uniform([2, 2]))

We get the following error:

[ERROR]   TestTensorflowModel.testTf2:98->testTf2:113 » IllegalState Encountered unexpected API call.

@tatianacv Do you have a stack trace for this?

This is just the input file. What about the test code?
