Pandasql returns error with a basic example

The following code when run

import pandas as pd
from pandasql import sqldf

df = pd.DataFrame({'col1': [1, 2, 3, 4], 'col2': [10, 20, 30, 40]})

query = "SELECT * FROM df WHERE col1 > 2"

result = sqldf(query, globals())
print(result)

gives the following error:

Output exceeds the size limit. Open the full output data in a text editor

   1411 except AttributeError as err:

The above exception was the direct cause of the following exception:

Could someone please help me?

The problem could be fixed by downgrading SQLAlchemy:

pip install SQLAlchemy==1.4.46
