TypeError: List of Tensors when single Tensor expected - when using const with tf.random_normal

Someone else has answered this question on another thread.

Essentially, tf.constant() takes a NumPy array as an argument or some sort of array or just a value.

tf.random_normal() returns a Tensor which cannot be an argument to tf.constant().

To fix this, use tf.Variable() instead of tf.constant().

See the answer from the link. The person explains it better.

tf.constant is supposed to have a constant argument - value. Here value can be a constant value or a list of values of type dtype. You can't create a constant tensor that has another tensor as its value.
