why jupyter file is not able to read csv file

I have used

import pandas as pd
data = pd.read_csv('C:\Users\Dell\Downloads\8. Netflix Dataset.csv')

but then it is showing this

errorSyntaxError: (unicode error)
'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

After this I have also used

data = pd.read_csv(r"C:\Users\Dell\Downloads\8. Netflix Dataset.csv")

but it then shows

FileNotFoundError: [Errno 2]
No such file or directory: 'C:\\Users\\Dell\\Downloads\\8. Netflix Dataset.csv'
