I have a question regarding the usage of the
resize_out function in PyTorch operations. Specifically, when I specify an
out tensor for an operation like
torch.max(x, out=y), it seems that the
resize_out function is called during the execution of the
max operation to check the device and dtype of the output tensor (
y). However, in the case of operations like
torch.mul(x, 3, out=y), it appears that the
resize_out function is not invoked.
I would like to understand under what circumstances the
resize_out function is called and when it is not. Are there specific criteria or conditions that determine whether an operation will utilize
resize_out to check the device and dtype of the specified output tensor?
