This is expected. You have to do this:
import random
from river import preprocessing
random.seed(42)
X = [{'x': random.uniform(8, 12), 'y': random.uniform(8, 12)} for _ in range(6)]
for x in X:
print(x)
scaler = preprocessing.StandardScaler(with_std=False)
for x in X:
scaler.learn_one(x)
scaler.transform_one(x)
I hope this is ok 🤗
Versions
river version: 0.21.2 Python version: 3.9.19 Operating system: Windows 10 22H2
Describe the bug
The preprocessing.StandardScaler.learn_one method returns None
Steps/code to reproduce
import random from river import preprocessing
random.seed(42) X = [{'x': random.uniform(8, 12), 'y': random.uniform(8, 12)} for _ in range(6)] for x in X: print(x)
scaler = preprocessing.StandardScaler(with_std=False)
for x in X: scaler.learn_one(x).transform_one(x)
