error loading module 'libcv' from file './libcv.so':

Hi Jure,

Thanks so much for sharing this code. I am trying to running the code following your instruction. However I get a error when I run the command

./main.lua kitti fast -a predict -net_fname net/net_kittifast-a_train_all.t7 -left samples/input/kittiL.png -right samples/input/kittiR.png -disp_max 70

error loading module 'libcv' from file './libcv.so': libcudart.so.7.5: cannot open shared object file: No such file or directory stack traceback: [C]: in function 'error' /home/fyl/torch/install/share/lua/5.1/trepl/init.lua:389: in function 'require' /home/fyl/MC-CNN/main.lua:5: in main chunk [C]: in function 'dofile' .../fyl/torch/install/lib/luarocks/rocks/trepl/scm-1/bin/th:150: in main chunk [C]: at 0x00406050

My CUDA version is 8.0, then I run the command : ldd libcv.so Here are the output: libcudart.so.7.5 => not found libnppc.so.7.5 => not found libnppi.so.7.5 => not found libnpps.so.7.5 => not found libcufft.so.7.5 => not found libcudart.so.7.5 => not found libnppc.so.7.5 => not found libnppi.so.7.5 => not found libnpps.so.7.5 => not found libcufft.so.7.5 => not found

Do you have any suggestions about it? Thanks!

Yiliu

Maybe you had cuda 7.5 installed when you compiled the mc-cnn code and some time later, your system updated your cuda version to 8.0. Try running make clean and make.

@jzbontar Thank you . The problem is the version of Opencv. Opencv2.4.12 do not support CUDA8.0, but Opencv2.4.13 do.

I see. I take it the problem is fixed now?

@jzbontar yes, the code can run successfully
