The method comprising: receiving a tensor including multiple channels of tensor values; determining whether one or more channel of the multiple channels satisfies a condition; in the case where one or more of the channels do not satisfy the condition, pruning the one or more channels from the tensor; signaling data representing the tensor where the data does not include the one or more pruned channels; and signaling information indicating which of the one or more channels have been pruned from the tensor.
