A Cython wrapper around card.io

cardio's Issues

ImportError: libdmz.so: undefined symbol: _ZN2cv8fastFreeEPv

I did everything that you said but i get the following error

make warning!

when I execute "make ", it shows:

cardio.cpp:1780:38: warning: implicit conversion loses integer precision: 'Scalar' (aka 'long') to 'int' [-Wshorten-64-to-32]
__pyx_t_2 = __Pyx_PyInt_From_int(__pyx_v_scan_result.predictions(__pyx_v_x)); if (unlikely(!__pyx_t_2)) __PYX_ER...

It seems that your Cython wrap convert 'Scalar' (aka 'long') to 'int', and output wrong card numbers.

Hi!
I have been trying to compile this project and run the python script on macOS Sierra (macOS 10.12.6) with a Darwin 16.7.0 Kernel, with the latest opencv version installed by brew, but I got this error

I would like to know how to complile the project to use cardio in my Mac

Thanks!
