   Hi, i just run a tensorflow model with TVM. My model has 317 inputs so i find create NDArray inputs for model is time consuming. 
   ```
   data = source_array.ctypes.data_as(ctypes.c_void_p)
   ```
   is used in funstion copyfrom when create NDArray, and i find use 
   ```
   data = ctypes.cast(source_array.__array_interface__['data'][0], ctypes.c_void_p)
   ```
   instead will save 0.35 ms for my model.
   
   I am not sure whether this modification is reasonable.
