Description
Environment
Machine: L20
Version: 2603 (latest)
CUDA Driver: 590.44.01
Docker Image: nvcr.io/nvidia/pytorch:26.02-py3 (as specified in Dockerfile),cuda 13.1
Steps to Reproduce
- run script:
./training/benchmark/scripts/run_all_experiments_local.sh \ --exp-file=training/benchmark/experiments.txt \ --nproc=2 --nsys - When using nsys profile with
-c cudaProfilerApi,no profiling file is generated. logged as:
Processing events... Generated: No reports were generated. - Expected output is A valid profiling report file (e.g., .nsys-rep or .sqlite) should be generated.
- The complete log is as follows:nsys.failed.logs.txt
- when nsys without
-c cudaProfilerApi, through nsys-rep file created,but we see only the CPU timeline, without GPU timeline, while NSys GUI say error :Subscribe returned 999: CUPTI_ERROR_UNKNOWN
Already Tried
- docker run with
--privilegedand--cap-add=SYS_ADMIN - stop the dcgm server on the host
- downgrade or upgrade nsys version
