Modin version checks

  • I have checked that this issue has not already been reported.

  • I have confirmed this bug exists on the latest released version of Modin.

  • I have confirmed this bug exists on the main branch of Modin. (In order to do this you can follow this guide.)

Reproducible Example

import modin.pandas as pd

df  = pd.DataFrame(dict(col1=[0], col2=[1]))
df.groupby("col1")["col2"].mean()

Issue Description

The implementation assumes "col1" can be copied.

Expected Behavior

We should not make this assumption 😄
