Add test cases using varying import statements

	import tensorflow as tf
	def add(a, b):
	return a + b
	c = add(tf.ones([1, 2]), tf.ones([2, 2])) # [[2., 2.], [2., 2.]]

Please add a test case that imports tf.ones in a different way, i.e., from tensorflow import ones (or something like that) and then change the code so that it reads:

c = add(ones([1, 2]), ones([2, 2]))

@tatianacv found out that we have such tests. For example:

ML/com.ibm.wala.cast.python.test/data/tf2c.py

Lines 1 to 8 in 93c96d8

	import tensorflow as tf
	from tensorflow.python.ops.array_ops import ones
	def add(a, b):
	return a + b
	c = add(tf.ones([1, 2]), ones([2, 2])) # [[2., 2.], [2., 2.]]

Which is tested here:

ML/com.ibm.wala.cast.python.ml.test/source/com/ibm/wala/cast/python/ml/test/TestTensorflowModel.java

Line 63 in 93c96d8

testTf2("tf2c.py", "add", 2, 2, 3);
