output of pd.show_versions()
all the versions and more info is in the full build log: http://neuro.debian.net/_files/_buildlogs/pandas/0.18.1+git25-ga7469cf/pandas_0.18.1+git25-ga7469cf-1_amd64.build but altogether versions are close/the same as in https://github.com/pydata/pandas/issues/14269#issue-178334362
