'Series' object has no attribute 'query'

This error usually occurs when you try to use the `query()` method on a pandas `Series` object. The `query()` method is only available for pandas `DataFrame` objects.
To resolve this error, you can convert your `Series` object into a `DataFrame` object using the `to_frame()` method and then use the `query()` method on the resulting `DataFrame`. Here's an example:
```python
import pandas as pd
# Create a Series object
data = pd.Series([1, 2, 3, 4, 5])
# Convert the Series to a DataFrame
df = data.to_frame()
# Use the query() method on the DataFrame
result = df.query('column_name > 2')
```
Replace `'column_name'` with the actual name of the column you want to query.
Alternatively, if you only need to filter the values in the Series based on a condition, you can use boolean indexing like this:
```python
filtered_data = data[data > 2]
```
This will return a new Series object with only the values that satisfy the condition.
