wkcn commented on issue #9880: TVM bridge support to JIT NDArray Function by TVM
URL: https://github.com/apache/incubator-mxnet/pull/9880#issuecomment-458790311
 
 
   @tqchen Hi!
   I would like to use `MXTVMBridge` to accelerate my project, but there is a flaky problem.
   
   I wrote a [minimum reproducible example](https://github.com/wkcn/test_tvm_bridge).
   In this example, `tvm_packed_func.h` is simplyfied from TVM.
   ### Steps to reproduce
   1. clone the example
   2. change the path of libmxnet.so in the line 55 of the code.
   3. make
   4. ./test
   
   In the function `SetMXTVMBridge` of the example,
   `args.num_args` is wrong and `args.values[0].v_str` is sometimes wrong when MXNet is installed by pip, namely `pip install mxnet --pre`.
   However, the result is right when MXNet is built by myself, `make -j 5 USE_OPENCV=1 USE_BLAS=openblas 
   ` in the latest MXNet source.
   The problem may be similar to the bug @merrymercy met.
   
   Thanks.
