I tried to debug the issue using lldb. I found that for the *this, src and index tensors all variables numel are correct. But when trying to get their sizes() it shows 1. I don’t really understand why this is happening. Also in the error message should tell which tensor was half constructed.

Also, an unrelated not do you know how I could get code completion and definition look. Right now I have to ag search the aten directory for finding what I want to use.
