With DataFrame colums tab does not work

Don't know if I updated something wrong, however when creating pandas and trying see list of functions with a dataframe, it creates the following:

df['col2']. --> press tab --> df['col2'],ipynb_checkpoints/

should I reinstall?

Reproduce the report in a Jupyter Notebook with pandas using df['col2'] and Tab completion. Compare the expected dataframe function suggestions with the reported ipynb_checkpoints/ entry; done means completion shows the relevant dataframe functions instead of that entry.
