python - Pandas str-methods not working: AttributeError: 'PandasArray' object has no attribute '_str_upper'

Question

I′m trying to get familiar with the pandas package. As I'm trying to manipulate strings in a column I get following error:

Traceback (most recent call last):
  File "C:/Python/Udemy/pandas/main.py", line 12, in <module>
    print(df["name"].str.upper())
  File "C:UserssaxalAppDataLocal
-minicondalibsite-packagespandascorestringsaccessor.py", line 101, in wrapper
    return func(self, *args, **kwargs)
  File "C:UserssaxalAppDataLocal
-minicondalibsite-packagespandascorestringsaccessor.py", line 2686, in upper
    result = self._array._str_upper()
AttributeError: 'PandasArray' object has no attribute '_str_upper'

I already tried installing different versions of numpy and pandas without success. Currently installed pandas 1.2.0 and numpy 1.19.5

If I run the exact same code e. g. on repl.it it works perfectly fine.

Example Code:

import pandas as pd

names = ["first name", "second name", "third name"]
numbers = [1,2,3]
data = {
    "name": names,
    "number": numbers
}

df = pd.DataFrame(data)

print(df["name"].str.upper())
