As I understand in Google Colab environment pandas is pre-installed. However the version it use it's not the recent one.
import pandas as pd
pd.__version__
>>0.22.0
When I want to install the latest version using
!pip install pandas==0.23.4
It is still use the 0.22.0 version instead of a new, even though the log message mentioned that 0.22.0 was successfully uninstalled.
How should I upgrade properly?
