Description
Hi,
Great repo! I have some questions about the bing_bert example: doesn't it support ZeRO? I tried stage 1 or 2, but it kept running into errors. If not using deepspeed transformers kernels, I encountered
Invalid to reduce Param 76 with None gradient
If using deepspeed transformers kernels, I encountered,
RuntimeError: CUDA error: misaligned address
I would really appreciate some help. Thanks in advance!

Research direction
Start with the bing_bert example and reproduce the reported runs using ZeRO stages 1 and 2, both with and without DeepSpeed transformer kernels. Trace the two reported errors to determine whether ZeRO is supported there; done means the example runs successfully or its compatibility limitation is documented.
