Return a tuple of integers indicating the version of this Op.

An empty tuple indicates an “unversioned” Op that will not be cached between processes.

The cache mechanism may erase cached modules that have been superseded by newer versions. See ModuleCache for details.


This function overrides c_code_cache_version unless it explicitly calls c_code_cache_version. The default implementation simply calls c_code_cache_version and ignores the node argument.
