Setting index = false in function to_csv is not working
#### Code Sample, a copy-pastable example if possible

```python
# Your code here
df_ = pd.DataFrame([predicted_labels])
display(df_)
df_.to_csv('person.csv',index=False)
```
#### Problem description

Actually I don't want index in my csv file so I set index = false but It's not resolving the issue, my CSV file still has index values.

#### Expected Output
3,6,0,6,3,0,6,6,6,6,6,0,2,6,6,6,0,0,2,0,0,0,6,0,2,6,6,6,6,6,3,6,3,6,2,0,6,0,6,6,3,2,6,6,6,6


#### Output of ``pd.show_versions()``
