Hi @tqchen, @masahi , I am new to tvm community. I was trying to implement maxpool3d operator based on reference implementation from tensorflow(r=1.14) into tvm codebase. For testing the same, I have written relay and topi test cases. I am also writing test cases in test_forward.py(for tensorflow) which compares tvm output with tensorflow output. I want to know is there any specific reason why you have not added any changes in test_forward.py(comparing tvm with tf) for unit testing?? Should i ignore this file altogether?
