Hi, I am trying to get the ImageColorToGrayscale from Module 3 to verify, but I always seem to get the error “Failed to grade solution.” This happens both when I use my own .cu file and the solution provided in the the teaching kit. Is there a configuration I am missing? I am running the latest teaching kit from the master on bitbucket.
Output below:
user@host:~/gputeachingkit-labs$ ./ImageColorToGrayscale_Solution -e ~/ece597_gpu/labs/lab03/code/work/ImageColorToGrayscale/Dataset/0/output.pbm -i ~/ece597_gpu/labs/lab03/code/work/ImageColorToGrayscale/Dataset/0/input.ppm
