Error when running colab

[Tizzzzy]

I am running the colab code in local using python 3.8.18, and it seems like I have successfully downloaded all the package, but when I run "agent.query_db("how many deaths of age below 40 had stomach cancer?")", it shows this error. Strangely, I can run this line "agent.get_query("how many deaths of age below 40 had stomach cancer?")"

I have the same issue, no matter what question I test on agent.query_db(). Any idea how to make it work ?
No problem with running agent.get_query(), though (except for some questionable results...)
