I was trying out fused op on V100 and got CUDNN_STATUS_BAD_PARAM while executing cudnnFusedOpsExecute():
Execute line: 43 cuDNN: CUDNN_STATUS_BAD_PARAM
Execute line: 43 cuDNN: CUDNN_STATUS_BAD_PARAM
According to API reference,this indicates the type of cudnnFusedOps_t in the plan descriptor is unsupported.
However,i checked all my settings and they all met the demand.
I turned on CUDNN_LOGERR_DBG/CUDNN_LOGWARN_DBG/CUDNN_LOGINFO_DBG,but didn’t get any err info.

Now i suspect that the problem comes from one of the inputs but i don’t know which. I’m wondering is there any means by which i can get useful debugging infomation?
Here’s my code:
