spyder: Pandas index type can't be viewed in variable viewer

Hi, it seems that certain (Int64Index in this case) built-in pandas.Index don’t work with the variable viewer.

I’m unsure if this is unique to Spyder 6 (Windows) or all versions (I’m using the standalone spyder 6 installer), and there could be other index types that dont work that I’m unaware of.

Here is a bit of reproducible code:

import pandas as pd
import datetime as dt

cols = pd.Index(range(5))
index = pd.Index(pd.bdate_range(dt.date.today(),periods=10))
data = {key : [i/1.25 for i in range(10)] for key in cols}

df = pd.DataFrame(data, index = index, columns = cols)
print(f'I work!:    {df.columns}')

df.columns = pd.Index([i for i in range(5)])

print(f'I dont work!:    {df.columns}')

(PS. Hopefully I dont make myself look silly by ignoring the very direct “dont report to github” message 😃 )
