Using the following code example:
import pandas as pd from typing import Dict class Test: def __init__(self, df : pd.DataFrame) -> None: self.df = df def example(self, replacements : Dict[str, str]) -> None: self.df = self.df.rename(columns = replacements) Nvim displays:
rename is definitely a member of a dataframe object, and Pyright is aware of the venv I'm using as I get pandas completion:
I even get completion of the member which is an "error"
I'm not sure what exactly to check / post to make things clearer as I'm only recently setting this up.
I think the question is basically - how do I get the LSP to recognise that this is a "known" member? I'm not sure how it determines that, I'd like to be able to use pandas without so many errors though.
