caffe.set_mode_cpu() error?

[Kevin George]

Actually I built caffe with only cpu support. Is the command 'caffe.set_mode_cpu() ' only used when we have built with gpu support so that we can switch to cpu when needed? I thought I might need it just to make sure that Caffe is using my cpu but I guess the build takes care of that. Also is this command required even when I have built with cpu support only?

Error I get-

So I have used this link where I have used the command "cmake -DCPU_ONLY=ON". But even after building with this successfully, I am still getting the same gpu error.

[Kevin George]

So does anyone know why the cuda error still persists even though I've built Caffe with CPU only?

Hi kevin,

            Could you plz post your "Makefile.Config" file. Would be better to resolve the issue.

[Kevin George]

I hate attached the file. If you would like to see further developments on this question, you can check it out on this stackoverflow link.

Hi,

I have never used CMAKE to build caffe, I find editing Makefile much easier option. If you still want to use CMAKE try this link

https://github.com/BVLC/caffe/pull/1667

other wise you can use MAKE. Use the attached file for MAKE. If you have ever used make for caffe, do not forget to do 'make clean' inside caffe root folder before building it again. 

for python layers -  WITH_PYTHON_LAYER := 1 should be uncommented inside Makefile.config.

Hi guys, it's almost been a week but I'm still stuck with compiling Caffe. I followed Suyog's instruction of using make to compile caffe but I'm getting the below error.

I am using python 3.4.3 with Opencv 3.2.0 on Ubuntu 14.04lts. My protobuf version is 3.1.0. I manually upgraded the protobuf from 2.5.0 to solve one error(I can't remember) but now I'm getting this. I have uploaded my Makefile. I have searched online for this error but I'm sadly not able to resolve it.
