Problem running on CPU machine

[varadgunjal]

Got this error running on a CPU machine (which had Caffe installed earlier), after following all the steps listed -

Any ideas what might be going wrong?

i met this problem too, have you solved it?

[varadgunjal]

I did get it to build completely by making changes in the makefile to build Caffe with CPU instead of the default GPU - however it still gave a runtime error. Finally, the only way I got it to run without issue was running it on a GPU : ensure you have the appropriate paths set in the makefile. If you face issues running it on a GPU, I could help you. Good luck.

i modified the makefile.config, and then i got another issues.

do i need to modify the makefile? thank you!

[varadgunjal]

Based on the error you are getting

undefined reference tocv::imread(cv::String const&, int)

it looks like you don't have OpenCV installed correctly on your machine. Try getting it with sudo apt-get install python-opencv and then re-compiling. I would just like to repeat, you have a better chance of getting this to run with a GPU - if you don't have access to one, by all means continue trying on a CPU.

thank you very much, i have solved the issue by adding the opencv_imgcodecs to LIBRARIES in the Makefile
