Segmentation fault when starting the service

[bowu]

Everything compiled successfully. I followed the tutorial by invoking:
./djinn --common ../common/ --weights weights/ --portno 8080 --gpu 1 --debug 0 --nets nets.txt
But saw:
Segmentation fault (core dumped)

The output from gdb is:

77 Caffe::set_phase(Caffe::TEST);
(gdb) n

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff668d8f3 in malloc_consolidate (av=av@entry=0x7ffff69cd760 <main_arena>) at malloc.c:4157
4157 malloc.c: No such file or directory.

Did anybody saw this before? Any help would be greatly appreciated.

I'm assuming you're trying to run it on the GPU so make sure that all the CPU_ONLY flags are set correctly (and match):

• in Caffe: https://github.com/jhauswald/caffe/blob/master/Makefile.config.example#L8
• in Djinn: https://github.com/claritylab/djinn/blob/master/common/Makefile.config#L11

Have you downloaded the djinn weights as well?

I compiled caffe and djinn again by following the instructions from the djinn website, but the problem still exists. The only change I made is about the caffe installation location. All the CPU_ONLY flags match your examples. Any clue would be appreciated.

BTW, I have Ubuntu 14.04 and a Titan Z card, and I can compile and run CUDA programs.
