Let us modify the function as tvm_wrap_excepthook(exception_hook) that returns a new wrapped hook, and then do

sys.excepthook = tvm_wrap_exceptionhook(sys.except_hook)

if hasattr(multiprocessing, 'active_children'):
# pylint: disable=not-callable
for p in multiprocessing.active_children():
p.terminate()
def tvm_wrap_excepthook(exception_hook):
"""Wrap given excepthook with TVM additional work."""

sys.excepthook = tvm_excepthook
def wrapper(exctype, value, trbk):
"""Clean subprocesses when TVM is interrupted."""
exception_hook(exctype, value, trbk)
if hasattr(multiprocessing, 'active_children'):
# pylint: disable=not-callable
for p in multiprocessing.active_children():
p.terminate()

return wrapper

sys.excepthook = tvm_wrap_excepthook(sys.excepthook)
