Can I run caffe-yolo on non-GPU machine?

[mohanadkaleia]

Hello, I'm trying to test YOLO model on Caffe on my local machine which I don't have GPU, Can I run YOLO using CPU-machine? Thank you

Sure you can. If you use my python script to test, just set "caffe.set_mode_cpu()" in the script when testing on a CPU-machine.

When I try to run: make -j8 it gives me the following error:

Have you set CPU_ONLY := 1 in the Makefile.config?

[mohanadkaleia]

Yes, I did

# CPU-only switch (uncomment to build without GPU support).
CPU_ONLY := 1

Do I need to set anything else?

[Harick1]

You can try removing the following lines in the detection_loss_layer.cpp #ifdef CPU_ONLY STUB_GPU(DetectionLossLayer); #endif

Great, it worked, Thank you, appreciate it
