This is a stateless version of tf.random.normal: if run twice with the same seeds and shapes, it will produce the same pseudorandom numbers. The output is consistent across multiple runs on the same hardware (and between CPU and GPU), but may change between versions of TensorFlow or on non-CPU/GPU hardware.

Args
shape	A 1-D integer Tensor or Python array. The shape of the output tensor.
seed	A shape [2] Tensor, the seed to the random number generator. Must have dtype int32 or int64. (When using XLA, only int32 is allowed.)
mean	A 0-D Tensor or Python value of type dtype. The mean of the normal distribution.
stddev	A 0-D Tensor or Python value of type dtype. The standard deviation of the normal distribution.
dtype	The float type of the output: float16, bfloat16, float32,float64. Defaults to float32.
name	A name for the operation (optional).
alg	The RNG algorithm used to generate the random numbers. Seetf.random.stateless_uniform for a detailed explanation.

Returns
A tensor of the specified shape filled with random normal values.
