1# Lazy Tensor Python Code 2 3Lazy Tensor Core is part of libtorch, which can not depend on python. 4 5Parts of lazy tensor core use python for 2 purposes 6A) py bindings let python programs call into lazy tensor c++ code 7B) lazy tensor core calls into python to use it (e.g. for grabbing stack traces) 8 9(A) is trivial since the python bindings only depend on libtorch; 10(B) requires making libtorch_python register a function with libtorch if loaded, and having a default (no-op) function otherwise. Any functionality that strictly needs to depend on python should be part of the 'python' folder. 11
