trying to do the following import:

from sklearn.metrics.regression import mean_absolute_error, mean_squared_error, r2_score

and I get error:

ModuleNotFoundError: No module named 'sklearn.metrics.regression'

tried fixing with installation of:

pip install -U scikit-learn scipy matplotlib

but I don't think that's what I'm missing since it didn't work...

CodePudding user response：

You're probably looking to import them from sklearn.metrics, not sklearn.metrics.regression

Link to the library

CodePudding user response：

What you are looking for is:

from sklearn import metrics 

metrics.mean_absolute_error(<your params here>)
metrics.mean_squared_error(<your params here>)
metrics.r2_score(<your params here>)

Edit

you can check the attributes of the metrics instance with:

dir(metrics)
