You can set out with the functions which have out argument as shown below:
*Memos:
- I selected some popular
keepdimargument functions such as arange(), rand() add(), mean(), median(), min(), max(), all(), any() and matmul(). -
out(Optional-Type:tensor) can have a returned tensor. *Sometimes,out(Optional-Type:tuple(tensor,tensor) orlist(tensor,tensor)). - Basically,
outcan be used with torch but not with a tensor. - Basically,
out=is needed. - Sometimes,
outneeds to be used withdim. - I recommend not to use
outargument because it is useless at all.
arange(). *My post explains arange():

# tensor([5, 9, 13])
tensor1 = torch.tensor([0, 1, 2])
tensor2 = torch.arange(start=5, end=15, step=4, out=tensor1)
tensor1, tensor2
