问题:

I am trying to profile a TensorFlow based code using nvprof. I am using following command for this

nvprof  python ass2.py

The program runs successfully but at the end it shows following error.

======== Error: Unable to import nvprof generated profile data.

回答1:

use /usr/local/cuda/bin/nvprof xxx, maybe you have install two versions of cuda

OR you can add /usr/local/cuda/bin to PATH enviroment.

vim ~/.bashrc
export PATH=$PATH:/usr/local/cuda/bin
source ~/.bashrc

I don't know the exact reason but using the full path of nvprof /usr/bin/nvprof solved the problem.
