Wanted to add another problem I'm facing. When I call tensorize with
call_extern within a AutoTVM template function it is not able to resolve the
external call. But the problem does not appear when the function is not
decorated as a AutoTVM template function. I load the dynamic library via
def load_lib():
"""Load library, the functions will be registered into TVM"""
curr_path = os.path.dirname(os.path.abspath(os.path.expanduser(__file__)))
# load in as global so the global extern symbol is visible to other dll.
lib = ctypes.CDLL(
os.path.join(curr_path, "../mylib.so"), ctypes.RTLD_GLOBAL)
return lib
_LIB = load_lib()
in the script that I invoke. mylib.so contains my external function called with
call_extern but is not resolved. Says symbol lookup error. The script uses
tensorize , and one of the intrinsic function is implmented by call_extern to a
function within the library.
