How can I see the stream_executor logs of xla?

[knightXun]

I want to see the steam_executor logs to diagnosis a certain bug. I already know TF_CPP_MIN_LOG_LEVEL=0 TF_CPP_MAX_VLOG_LEVEL=2 output the full xla logs, but it make too many noise.

You can specify vlog level by module, e.g. TF_CPP_VMODULE=stream_executor=2.

Just to confirm, you set is as environment variable, not passing as the flag, right?

https://github.com/pytorch/xla/blob/master/TROUBLESHOOTING.md says you'd also need TF_CPP_MIN_LOG_LEVEL=0, but otherwise it should work.

I use these flags like this: TF_CPP_MIN_LOG_LEVEL=0 TF_CPP_MAX_VLOG_LEVEL=2 TF_CPP_VMODULE=stream_executor=10 python nmnist_exodus_snn.py
