[Bug]: Pandas Output: There was an error running the output as Python code. Error message: name 'p' is not defined #13800
Comments
To resolve the "name 'p' is not defined" error when generating a bar chart using Here is an example of how you can modify the code to include the plotting logic: import pandas as pd

from llama_index.llms.openai import OpenAI
df = pd.DataFrame(

The error "name 'p' is not defined" suggests that there is a missing import or a typo in the code being executed. Specifically, it seems like the code is trying to use a variable or function named To resolve this, ensure that all necessary libraries are imported and used correctly.
