Everything looks fine when I run though all the examples.

Not deleting this line of code will result in NULL gradient when using the stop_gradient API.

LayerNorm uses tf.nn.moments and tf.nn.moments uses the stop_gradient API. If this line of code is not deleted, an error will be reported. Deleting this line of code will enable normal training.

tf.nn.moments: There may be a problem where the gradient isnullduring the training, it seems that removing the 681st line of code from the[TensorFlowNET.Core/Operations/array_ops.cs]can solve this issue.tf.nn.batch_normalization: Usenn_impl.batch_normalizationto reuse code.
