KellenSunderland commented on issue #9681: Better Exception Handling for Operators URL: https://github.com/apache/incubator-mxnet/pull/9681#issuecomment-363371337 @anirudh2290 Good idea to use an example. From my perspective as a user I generally prefer that things fail as quickly as possible for me so that I don't have to track down root causes. Following this logic, I'd tend to agree with you, but would actually prefer it if this line threw an exception: ```python try: x, y, z = op() x.asnumpy() except: handle_exc() y = op2(y) # Runtime exception y.asnumpy() ``` I understand that this is a lazy operation, but wonder if it's still possible to do some failure validation here? If not the first blocking call (asnumpy) would also be a fairly intuitive place to throw.
