about UserWarning!

[RYHSmmc]

Hello, when training SED, I meet the following warning, anythone know if it need to be fixed?
UserWarning: Grad strides do not match bucket view strides. This may indicate grad was not created according to the gradient layout contract, or that the param's strides changed since DDP was constructed. This is not an error, but may impair performance.
grad.sizes() = [1024, 1, 7, 7], strides() = [49, 1, 7, 1]
