python - Flask : 'Token' object has no attribute 'test' | render_template error

Code in Fake_News_Det.py :

from flask import Flask, render_template, request
from sklearn.feature_extraction.text import TfidfVectorizer
from sklearn.linear_model import PassiveAggressiveClassifier
import pickle
import pandas as pd
from sklearn.model_selection import train_test_split

app = Flask(__name__)
tfvect = TfidfVectorizer(stop_words='english', max_df=0.7)
loaded_model = pickle.load(open('D:Fake_News_Detectionmodel.pkl', 'rb'))
dataframe = pd.read_csv('D:Fake_News_Detectiondata.csv')
x = dataframe['text']
y = dataframe['label']
x_train, x_test, y_train, y_test = train_test_split(x, y, test_size=0.2, random_state=0)

def fake_news_det(news):
    tfid_x_train = tfvect.fit_transform(x_train)
    tfid_x_test = tfvect.transform(x_test)
    input_data = [news]
    vectorized_input_data = tfvect.transform(input_data)
    prediction = loaded_model.predict(vectorized_input_data)
    return prediction

@app.route('/')
def home():
    return render_template('index.html')

@app.route('/predict', methods=['POST'])
def predict():
    if request.method == 'POST':
        message = request.form['message']
        pred = fake_news_det(message)
        print(pred)
        return render_template('index.html', prediction=pred)
    else:
        return render_template('index.html', prediction="Something went wrong")

if __name__ == '__main__':
    app.run(debug=True)

After running the code, and viewing it on local port it shows an error :-

AttributeError AttributeError: 'Token' object has no attribute 'test'

It have list of errors in sequence of type jinja errors, but what I think is

File "D:Fake_News_DetectionFake_News_Det.py", line 31, in home
return render_template('index.html')

This has something to do with, although I have index.html file in templates folder

I had the same problem.

I had Jinja2 3.0.1, I went down to 2.11.3, and it fixed the problem.
