tkclimb opened a new pull request #4483: [WIP][relay][op] add expand op (from ONNX) to relay frontend
URL: https://github.com/apache/incubator-tvm/pull/4483
 
 
   I added ONNX expand op into relay ONNX frontend, which I discussed in the following thread.
   https://discuss.tvm.ai/t/tvm-error-opnotimplemented-the-following-operators-are-not-supported-for-frontend-onnx-expand/2688/8
   
   In this request, Since the expand op seems to be same as `op.broadcast_to(..)` , I just add forwarding process from ONNX expand op to it in the frontend layer. I didn't add any op here.
   I have already tested it with a network includes expand op inside but I haven't succeeded to run `test_forward.py` yet by some reason. I just want someone to check the location where I added the operator and the test is proper or not, also any other suggestions are welcome of-course.
