Description

Errors when trying to use partial_fit in a variety of ways - I am getting this with int or string values for y and with and without providing classes to partial_fit. Could you point me to what I'm doing wrong here?

import numpy as np
from treeple import PatchObliqueRandomForestClassifier

X = np.array([[1, 2, 3]]).T
y = np.array(["x", "y", "z"])
classes = y
porf = PatchObliqueRandomForestClassifier()
porf.fit(X, y, classes=classes)
porf.partial_fit(X, y, classes=classes)
