to_yaml not working with 1.9.4

For some reason I keep getting this error when using the to_yaml function:

print(t.to_yaml())
AttributeError: 'Template' object has no attribute 'to_yaml'

troposphere-1.9.4.egg-info

Did a pip install troposphere[policy] --upgrade

I don't see any of the cfn_flip stuff in the files. I'm not sure why 1.9.4 doesn't have this when I use pip install.

Thank you.

Start by inspecting the installed troposphere-1.9.4.egg-info and package contents, then compare them with the source version that provides Template.to_yaml and the cfn_flip components mentioned in the report. Done means identifying why pip install troposphere[policy] omits the expected functionality and documenting or correcting the package contents.
