CMakeFiles/normalSpeed.dir/build.make:110: recipe for target 'CMakeFiles/normalSpeed.dir/np2mat/ndarray_converter.cpp.o' failed
make[2]: *** [CMakeFiles/normalSpeed.dir/np2mat/ndarray_converter.cpp.o] Error 1

This happens when I try to install it. Pybind 11 and opencv3 were installed using pip3. Any ideas what's wrong here?

More info about the bug, can someone help me understand what's the problem here?

Hello @Gauravajariwal11 ,
I encounter exactly the same problem. Have you managed to resolve it ?
I would really appreciate it if you could help me on that.
Thanks !
