assert(cv_img2.cols==xSize && cv_img1.rows==ySize ); should be changed toassert(cv_img2.cols==xSize && cv_img2.rows==ySize );

when I run : make -j 5 all tools pycaffe I get error do you know how to solve it ? Could you help me ? The error like this:

@gyguo You're right, thanks!

@strivejin

tools/convert_imageset_and_disparity.cpp:156:31: error: ‘numeric_limits’ is not a member of ‘std’
value=std::numeric_limits::max();
^

There's something about your system that I don't understand. This error should not happen: <limits> is included (and does not throw an error) and you are using GCC 5.3 on Ubuntu 16.04. But you don't get the whole output from VERBOSE=1 make and your compiler does not find std::numeric_limits which is in <limits>.

Does the file /usr/include/limits.h exist on your system?

[strivejin]

@nikolausmayer

thanks for your reply. The file /usr/include/limits.h exist on my system. I also change the gcc version to gcc5.4 . I tried a lot of ways，but it still do not work. I think there may be some problems with my system. I will try to reinstall my Ubuntu 16.04，then try it again.

@nikolausmayer

I am so happy I can run it by reinstall my system . I run it in Ubuntu 16.04 ,gcc 5.4 ,CUDA 8 ,CUDNN 5.1 ,Opencv3.1. And add #include in 'convert_imageset_and_flow.cpp'. Thank you very much.

@gyguo fixed in https://github.com/lmb-freiburg/flownet2/commit/9eed763789c06fa5f44e7af79078c0446a82bfc6

@strivejin good to hear :) although still a strange issue

[ggaziv]

@nikolausmayer Similarly, missing #include <limits> in tools/convert_imageset_and_flow.cpp results in tools/convert_imageset_and_flow.cpp <...> error: ‘numeric_limits’ is not a member of ‘std’ value=std::numeric_limits::max(); I believe that was caused the issue for @strivejin as well. Thanks, Guy
