Error when loading classifier (SOLVED)

[vincen]

Solution : There was an acent in the file path that caused the .yaml to not save !

Hello, me again

When I try to load the classifier .txt file in the classification step, i get this error :

error(-215)fs.isOpened() uin fuction cv::Algorithm::load

I have no idea what this means.

Thank You

Please, give more precision on the steps of your use case.
Did you train your classifier?
If yes, did you save it?
If yes, did you open the classifier to try to classify your points or did you open the initial parameter file (which will fail).

[vincen]

Yes I trained the classifier.

Yes I saved it.

Yes i opened the classifier file.

Still not working.

There is no .yaml file in the project foleder.. onyl .txt

When you save the classifier at the end of the training phase, you shall get a .yaml file with the exact same name as the associated .txt file (the name you choose for the classifier, as in classifier.txt and classifier.yaml). Could you check that?

Can you copy the .txt file you are talking about?

Linux, Windows or Mac?

[vincen]

It says in the command line that there is a .yaml file saved in the folder but i cannot find it !
Im on windows

Here is the classifier.txt file

What do you mean by 'command line'? The console of the GUI of CloudCompare? Did you launch the plugin in command line with a terminal?

Please avoid to create duplicate threads on the same topic, this does not ease the discussion.

[vincen]

Yes the console of the GUI in CloudComapre.

[SOLVED]
The error came from the directory in which the classifier was saved. The path to this directory included an accent.
[SOLUTION]
Remove any accent from the path.
