5 years ago Hi Jambon, Is cv4 the default on your distro at this point, or are you just experimenting? I'm not sure I'll have the time at the moment to setup a new environment, but I'm happy to help you debug the issue. Can you post your OS version, and any changed or manually installed packages?
Running the unit tests would be a good start to pinning down what changed (python setup.py test).
From there, if you have a specific failing test, but are still not sure what is causing the problem, you can attach a debugger on the failing line (import pdb; pdb.set_trace()), inspect variables, and keep following the code backwards to see where the difference is compared to a working environment.
In this case it looks like either the interface to knn.train changed and you'll have to do something like _.reshape(len(_), -1) (_ being the offending variable/s), or that some other code should be returning a one-dimentional array and no longer is.

Hi Goncalo, any plan to make it compatible with openCV 4.0? I was integrating your code in a new virtualenv which took the last openCV version 4.0 and I came up with below error after tweaking the version check
