Segmentation fault when using "caffe time" #100

Closed kindloaf closed 7 years ago

kindloaf commented 7 years ago

Hi, I'm trying to run caffe time on an android device. I used the following command:

~/platform-tools/adb shell 'cd /data/local/tmp/tmp; LD_LIBRARY_PATH=.:.. ./caffe time --model=a.prototxt'
invalid address or address of corrupt block 0x55955c39d0 passed to dlfree
Segmentation fault

Here is the call stack, although the real error could have happened in a different place:

Any advice?

Does it work if you try to compile and run caffe time via CK?

I.e. $ ck compile program:caffe-time --target_os=android21-arm64 $ ck run program:caffe-time --target_os=android21-arm64

It worked! Thanks a lot.

By the way, the command I used was against "program:caffe-time-opencl".

Sure, we had to separate CPU/OpenCL/CUDA versions due to linking of different libraries (it was just simpler at this stage since Caffe has different branches for OpenCL and non-OpenCL versions) ...
