# version 1

# version 2

    shape,

# Args
# shape	| A 1-D integer Tensor or Python array. The shape of the output tensor.
# mean	| A Tensor or Python value of type dtype, broadcastable with stddev. The mean of the normal distribution.
# stddev| A Tensor or Python value of type dtype, broadcastable with mean. The standard deviation of the normal distribution.
# dtype	| The float type of the output: float16, bfloat16, float32, float64. Defaults to float32.
# seed	| A Python integer. Used to create a random seed for the distribution. See tf.random.set_seed for behavior.
# name	| A name for the operation (optional).
