QUESTION

cross_val_score is returning nan list of scores in scikit learn

Asked 2020-Nov-21 at 15:59

I am trying to handle imbalanced multi label dataset using cross validation but scikit learn cross_val_score is returning nan list of values on running classifier. Here is the code:

import pandas as pd
import numpy as np
data = pd.DataFrame.from_dict(dict, orient = 'index') # save the given data below in dict variable to run this line

from sklearn.model_selection import train_test_split
from sklearn.feature_extraction.text import TfidfVectorizer
from sklearn.preprocessing import MultiLabelBinarizer
from sklearn.multiclass import OneVsRestClassifier

multilabel = MultiLabelBinarizer()
y = multilabel.fit_transform(data['Tags']) 
from nltk.corpus import stopwords 
stop_words = set(stopwords.words('english')) 
tfidf = TfidfVectorizer(stop_words = stop_words,max_features= 40000, ngram_range = (1,3))
X = tfidf.fit_transform(data['cleaned_title'])

from skmultilearn.model_selection import IterativeStratification
k_fold = IterativeStratification(n_splits=10, order=1)


from sklearn.linear_model import LogisticRegression
from sklearn.metrics import jaccard_score
class_weight = {0:1,1:10}
lr = LogisticRegression(class_weight = class_weight, n_jobs = -1)
scores = cross_val_score(lr, X, y, cv=k_fold, scoring = 'f1_micro')
scores

Here is the data (first 10 rows) using data.head(10).to_dict()

This is how I get the cross_val_score in scores variable array([nan, nan, nan, nan, nan, nan, nan, nan, nan, nan]). It should have each value in range 0-1. However, this is happening with every algorithm model.

I think you need to change the model inside the line of the scores:

scores = cross_val_score(lr, X, y, cv=k_fold, scoring = 'f1_micro')
scores
