ChaiBapchya opened a new issue #13187: Inconsistent return types of random_generator functions in cpu and gpu
URL: https://github.com/apache/incubator-mxnet/issues/13187
 
 
   The file - `/incubator-mxnet/include/mxnet/random_generator.h` includes CPU and GPU implementation of random number generator functions.
   
   Close look at `cpu` implementation
   ```
   MSHADOW_XINLINE FType uniform() {...}
   MSHADOW_XINLINE FType normal() {...}
   ```
   
   While in case of `gpu`
   ```
   MSHADOW_FORCE_INLINE __device__ float uniform() {...}
   MSHADOW_FORCE_INLINE __device__ float normal() {...}
   ```
   
   Why is it hardcoded in gpu? Shouldn't it be generic?
