Error at Predict Classification (RF)

[Agustin Lobo]

I get this error when I try to predict a classification from an existing pkl model (RF):

I assume that FX17_SFpanel_subsc_PC.envi is the file used for training, and you removed that file afterwards. This is a known issue, and we will fix this in a future version. For now you have to keep the files used for training (which is not so nice).

[Agustin Lobo]

What do you mean by “you removed that file afterwards”? I do have load it

‌

[Andreas Janz]

At the time you trained the model, you used this file: E:/Ignacio2019/SanFinx/SanFinx-Emma/Classification/Gisela_Panel/FX17_SFpanel_subsc_PC.envi

I guess, this file has been moved elsewhere, right?

[Agustin Lobo]

Even with the image loaded in EnMapBox?? This is really inconvenient, hope you can fix it very soon.

Please check if this is now solved in the new classification algo.
