[Track v1.4] New PR branch to serve as submodule for scikit-tree

[adam2392]

Reference Issues/PRs

As of v0.2 for sktree, we have decided we do not need a custom built and released via pypi scikit-learn fork. Instead, we just have to keep an updated fork branch here that maintains the changes under tree/ and ensemble/.

This branch has significantly lower diff and less complexity compared to e.g. #44

What does this implement/fix? Explain your changes.

Any other comments?

I cannot reproduce the error on my local machine with following code:

from sklearn.ensemble import RandomForestClassifier

import numpy as np
from inspect import signature

rnd = np.random.RandomState(0)
n_samples = 30
X = rnd.uniform(size=(n_samples, 3))
y = np.arange(n_samples)

clf_1 = RandomForestClassifier()
clf_1.set_params(random_state=0)

func = getattr(clf_1, "fit", None)
func(X,y)
args = [p.name for p in signature(func).parameters.values()]

func = getattr(clf_1, "score", None)
func(X,y)
args = [p.name for p in signature(func).parameters.values()]

func = getattr(clf_1, "partial_fit", None)
func(X,y)
args = [p.name for p in signature(func).parameters.values()]

The code should replicate most of the check_fit_score_takes_y test, but it runs smoothly every time. I also don't understand why only these 2 CIs failed when all should have the same test library.

If you try running the HonestForestClassifier instead, then the error seems to be able to be produced on my computer

@adam2392 Is sktree updated with the current submodule? After the resizing bug is fixed?

[adam2392]

Yeah it should be. The test is commented out tho rn.

[PSSF23]

All CIs passed.
