Training in CPU only mode very slow

Open sachinroyxavier opened this issue 9 years ago • 2 comments

Hi all, I am using caffe in CPU only mode and made the changes in _solver.prototxt. For 80 iterations i was taking abou 6 hours. I was not able to finish the training of segnet, basic as we ĺl as with the pretrained encoder. My CPU infos are i7 quad core@ 2.90Ghz and 8Gb RAM.

Am I missing something in the prototxt files or is this the expected behaviour? Thanks in advance for the help.

I am also new to caffe but as far as I know, it is not strange that CPU takes longer time. Maybe you can reduce the batch_size in training prototxt.

Me too. 35 minutes for 20 iterations. So bad. any solutions?
