Question

我尝试通过以下命令对 https://github.com/NVIDIA/waveglow 进行配置：

nv-nsight-cu-cli --export ./nsight_output ~/.virtualenvs/waveglow/bin/python3 inference.py -f <(ls mel_spectrograms/*.pt) -w waveglow_256channels.pt -o . --is_fp16 -s 0.6

Python命令来自https://github.com/NVIDIA/waveglow#generate-audio-with-our-pre-existing-model的指令，并且它可以与Nsight System配合使用，而不与Nsight Compute配合使用。

分析不会结束打印此日志；所以我按了Ctrl + C。另外，它仅分析一个内核，但是我有更多内核。（由Nsight Systems检查）

OS：CentOS Linux 7，Nsight Compute（2019.3.1，内部版本26317742）， GPU：Tesla V100-PCIE-32GB

我该如何解决？

Answer 1

我认为这里没有任何错误，该工具的行为符合预期。它不仅剖析了一个内核，而且还剖析了日志输出中已经存在的296个内核启动（似乎全部来自一个内核函数）。

您可以控制使用以下命令分析的内核的数量或类型： --launch-count或--kernel-regex选项。您还可以使用--metrics和--section来控制为每个内核收集的指标，因为收集更少的指标可以减少工具的开销。

有关更多可用的命令行选项，请参见https://docs.nvidia.com/nsight-compute/NsightComputeCli/index.html#command-line-options。

Nsight Compute无法分析Waveglow（PyTorch应用程序）
