[RFC][Tensorcore] INT4 end-to-end inference

Hello zachzzc, I’m having a hard time trying to run this implementation.

Can you print out the strategy.specializations in op/relay/compile_engine.py :120 and see if it is not empty while running your code?

Now I’ve fixed the hard coded 'hawq_utils_resnet50.py" file to fit resnet 18, and now I get the exact same error as the ‘test_resnet_inference_time.py’ that I mentioned above.

I’ve been working on this for days but couldn’t find what strategy.specializations is, and what it should contain.

Thank you in advance,
