using VS2017 compiled TVM source to generated tvm.dll ,but when we import this library to python.We found that the function name has changed in tvm.dll library. python unable to find the interface function defined in TVM。 The VS compiler has changed the function name. How to solve this problem？ or TVM does not support this?
