Metrics calculation in Prediction widget is possibly wrong. #4704

Hi!

It seems that the calculation of the metrics (Precision, Recall ...) obtained by Prediction widget is wrong. I am sending you .ows file where I used iris data set and KNN model.

Regards, Marin

Which Orange version is this?

mkosovic1981 commented 4 years ago

Sorry, I forgot to place the version. It is 3.23.1

janezd commented 4 years ago

Thanks. Unless I'm mistaken, this is a duplicate of #4029, which has been fixed in 3.24. Please update and report back.

mkosovic1981 commented 4 years ago

It works perfectly with the latest version 3.25.0

The thing is that Anaconda by default does not update Orange3 to the latest version, but the maximum version that can be obtained is 3.23.1 Why is that?

janezd commented 4 years ago

The latest version of Orange is available only on channel conda-forge. See https://orange.biolab.si/blog/2020/2020-02-24-anaconda-navigator/.
