[FIXED] ImportError: cannot import name 'det_curve' from 'sklearn.metrics'

Issue

I don't know why I am getting this error, the official document reference
https://scikit-learn.org/stable/modules/generated/sklearn.metrics.det_curve.html#sklearn.metrics.det_curve

Code:

import numpy as np
from sklearn.metrics import det_curve

fpr, fnr, thresholds = det_curve(y_test, y_pred)
print(fpr, fnr, thresholds) 

Error:

Solution

Looks like some issue with a missing package. Try the following:

pip uninstall -v scikit-learn

pip install -v scikit-learn

This might install the related dependencies along with it.
