how do i solve AttributeError: 'float' object has no attribute 'encode'

Question

this is the code

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns

plt.style.use('ggplot')

import nltk

df = pd.read_csv('/kaggle/input/starbucks-review-play-store/starbucksEN.csv',sep=",", encoding="utf-8")
df = df.head(70000)

ax = df\['Score'\].value_counts().sort_index() \
.plot(kind='bar',
title='Count of Reviews by Stars',
figsize=(10, 5))
ax.set_xlabel('Review Stars')
plt.show()

from nltk.sentiment import SentimentIntensityAnalyzer
from tqdm.notebook import tqdm

sia = SentimentIntensityAnalyzer()

res = {}
for i, row in tqdm(df.iterrows(), total=len(df)):
text = row\['Text'\]
myid = row\['Id'\]
res\[myid\] = sia.polarity_scores(text)

this is what show up
