Can't find cache dir on Mac OSX #120
Description
I get the following error when initiating the connector, although the cache dir does exist.
I'm running this from a Jupyter Notebook, Python 3.
---> 10 connector = APIConnector(apikey = key)

FileNotFoundError: [Errno 2] No such file or directory: '~/.openml/cache'
Is it possible that the home dir is not found with '~'?
