AttributeError: 'bool' object has no attribute 'tolist'

Hello, I've been learning how to use River, especifically for a project that involves SAMKNN. I was able to replicate the site example for SAMKNN, and was trying to use the classifier to evaluate a dataset from a csv file using iter_csv. Unfortunately, with a very simple use I already can't use it, it keeps giving the error AttributeError: 'bool' object has no attribute 'tolist' when I try to do an evaluate.progressive_val_score().

`from river import stream

converters = {'1': float, '2': float}
target = '3'

dataset = stream.iter_csv("C:/Users/Pichau/Documents/GitHub/research-project-stream-learning/lazy/fgt-sam-knn-tests/1000-recent/interchanging-rbf/interchanging.csv", converters=converters, target= target)

from river import neighbors

model = neighbors.SAMKNNClassifier(n_neighbors=3)

from river import metrics

metric = metrics.Accuracy()

from river import evaluate

print(evaluate.progressive_val_score(dataset, model, metric))`
