[GitHub] [incubator-mxnet] leezu commented on issue #18788: bfloat16 rendered as uint16

   MXNet bfloat16 type is registered as having numpy equivalent `np.dtype([('bfloat16', np.uint16)])`:

   As printing a NDArray works via converting to numpy, this causes `bfloat16` arrays to be printed as `uint16`.
   
   The fundamental issue here is that numpy does not support `bfloat16`. We can consider if there is a better solution
