Backwards Incompatible Changes

Python Frontend

import torch can no longer be re-executed in the same process, including via importlib.reload(torch) (#194654)

importlib.reload(torch) and del sys.modules["torch"] + re-import now raise, as does retrying import torch after it failed. Re-running the module body was already unsafe in exactly the same way as the retry, so the new check does not distinguish the two. Normal use is unaffected: a successful import leaves torch in sys.modules so the body never re-runs, and re-entrant imports from a backend extension during autoload still short-circuit on sys.modules without reaching the check.

Version 2.14:

import importlib
import torch
importlib.reload(torch)
RuntimeError: Only a single TORCH_LIBRARY can be used to register the namespace triton; ...
(re-importing after a failed import torch failed with similarly misleading errors or could segfault)

Version 2.15:

import importlib
import torch
importlib.reload(torch)
