TensorFlow Tensors and Operations

Question 1

What is the rank of a scalar tensor in TensorFlow?

Accepted Answer

0

Answer

A scalar is a rank-0 tensor because it has no axes.

Question 2

Which TensorFlow function creates a tensor filled with zeros?

Accepted Answer

tf.zeros()

Answer

tf.zeros() creates a tensor of the specified shape with all elements set to 0.

Question 3

What does tf.cast() do in TensorFlow?

Accepted Answer

Changes a tensor's data type

Answer

tf.cast() converts a tensor from one data type to another, such as from float32 to int32.

Question 4

Which attribute gives you the number of elements in a TensorFlow tensor?

Accepted Answer

tf.size()

Answer

tf.size() returns the total number of elements across all dimensions of a tensor.

Question 5

What does tf.reshape() require to be consistent?

Accepted Answer

Total number of elements

Answer

tf.reshape() requires the total number of elements in the new shape to match the original tensor.
