Nsight Compute can'；t剖面波辉光（PyTorch应用）

我试图通过以下命令配置文件：

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

操作系统：CentOS Linux 7，Nsight Compute（2019.3.1，构建26317742）， GPU:Tesla V100-PCIE-32GB

如何修复此问题？

我认为这里没有任何错误，工具的行为与预期一致。它不仅分析了一个内核，还分析了日志输出中已经启动的296个内核（看起来都来自一个内核函数）

您可以控制使用--launch count或--kernel regex选项分析的内核的数量或类型。您还可以使用--metrics和--section控制为每个内核收集的度量，因为收集较少的度量可以减少工具的开销
