Reinstall opencv and step on the pit.

Write it at the front ： This installation is on Ubuntu 16.04 Platform installation , Not only do you need to configure opencv You also need to configure annaconda, Because it was installed before , Therefore, there are many errors reported this time .

summary ： To avoid potential Python Or others Conflict , You should install opencv To configure annaconda Environmental Science , otherwise Can lead to annaconda The configuration in the environment is the same as that of other installations Configuration conflict , Such conflicts are generally difficult to detect , So before that, open ~ .bashrc Document notes are related to annaconda Configuration and related Python Configuration of ( Only note the installed , Do not comment on its system configuration );

Finally!!!
This undefined bug is because boost and linux system have the same regex.h file. And renaming this file of boost temporally can fix this. ref: https://groups.google.com/forum/#!searchin/caffe-users/regex.h/caffe-users/zTfFsRnNl9c/ckD-bar6BAAJ
So at the end I use my boost 1.59 and opencv2.4.12. and make the right opencv path for denseflow. this bug is fixed.

// This is because boost Kuhe linux system The library has the same regex.h, Delete boost library , Install if necessary ;

4. Solution

Custom build environments are not tested and probably not supported.
TIFF may depend on JPEG codec. You have these libs in different “locations”.,
// In different places , Multiple versions are installed tiff5–> Remove redundant tiff5, see .bashrc Is it in line with what you started to write ;

ps: install tiff5
