I am new at cuda programming when I was trying to use nvprof command on command window I got cupta64_102.dll not found the error but when I google it I couldn’t find anything related to cupta64_102.dll… can someone explain the reason and solution?

even if I try to use just “nvprof” I got the same error

sorry, it is cupti64_102.dll

Program can bot execututed because cupti64_102 didn’t found. reinstalling the program may fix this problem

Okey I fixed the problem

For the benefit of anyone else the file is <CUDA_INSTALL_DIR>/extras/CUPTI/lib64 and I’ve just copied it to <CUDA_INSTALL_DIR>/bin (where nvprof is)

Out of interest how did you fix it? Did you do the same?

I found cupti_64_102.dll file at <CUDA_INSTALL_DIR>/extras/CUPTI/lib64 and I copied it to windows/system32 but now I have a problem about nvprof —metrics branch_efficiency

  1. For Windows, Please add the corresponding folder to PATH variable:
    C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\extras\CUPTI\lib64
  2. Open a new cmd prompt, now please try: nvprof --help

THIS worked wonders for me

I copied the files from the mentioned folder to ‘bin’ folder and it worked for me. Although adding the mentioned path as the environment variables also should work. Thank you for the solution.
