CUDA_ERROR_ILLEGAL_ADDRESS Issue

[FrankCAN]

Hi, Is there anyone who meets the CUDA problem as below:

E tensorflow/stream_executor/cuda/cuda_event.cc:49] Error polling for event status: failed to query event: CUDA_ERROR_ILLEGAL_ADDRESS F tensorflow/core/common_runtime/gpu/gpu_event_mgr.cc:203] Unexpected Event status: 1

Many thanks for your help.

I met this when point didn't have neighbors. Query_ball_point returns garbage within uninitialized array, and finally, gather operation tries to read from incorrect address. I'm still trying to realize what is correct behavior in this case.

@FilatovArtm Indeed this was the cause of CUDA_ERROR_ILLEGAL_ADDRESS for me. I tried using query_ball_point on two disjoint point sets.
