Hi everyone,
I am using ATen’s tensor library in my C++ project, and I am having a problem now.
In Python, if I have a tensor tmp, then I can do the following code to add 100 to all the values in tmp that is less than zero.
tmp[tmp < 0].add_(100)

I hope to do the similar in C++. I try to do:
tmp.index(tmp < 0).add_(100)

However, it seems index() create a new tensor storage and the change only happens on new tensor, the original tmp is unchanged.
I checked other similar functions, e.g. index_select, and they all do not meet the need.
Would anyone know this part and please give me some advice.
Thank you!
