[AlexGbenimachor]

Good day,
Please, I'm having a problem setting up the caffe, because I get an error from the constrative_loss file, is like their is something wrong with file and how do I fix. thank you and I wait in anticipation for your reply.
Best Regards

Below is the Error in the code.

I had to downgrade my gcc and g++ to run the code but i got a protobuf error, it their way to go round this. thank you
