how to solve my question? where is wrong?

(this question in Attached Files)

thanks.

Well obviously you compiled caffe in CPU-only mode (look at your Makefile.config) but still try to use it in GPU-mode, which obviously doesn't work. Either recompile caffe with GPU features (you need an NVidia card and CUDA for that) or change the solver you use to CPU mode (There is a wuite obvious flag in there).

I am already to try again.

what is your mean for "change the solver you use to CPU mode (There is a wuite obvious flag in there)"?
that is in caffe.cpp? or common.cpp ? 

Help me , plz .

When the solver you use contains the line "solver_mode: CPU" and you compiled caffe with CPU_ONLY set in Makefile.config everything should work fine. What command have you executed to get that output from your first post? Maybe try to recompile everything (make clean && make all)

Hi Chias, were you able to solve this?

[Francisco Vargas]

Solver where? the vagueness in these responses are very unhelpful. I compiled everything with cpu only however still have this issue. The docs are not very great with this either.

 In the solver file there should be one line "solver_mode: GPU", change this line to  "solver_mode: CPU".

OK

No! The error is caused way earlier, on the compilation stage. Look in your Makefile.config, search for the line
# CPU_ONLY := 1
or
CPU_ONLY := 1
If you find this line uncommented, caffe gets compiled - obviously - for use only with CPU.
