keyerror on any english transliteration

[jeremy-rutman]

I wanted to give this a whirl but hit some speedbump from the getgo :

In [2]: epi = epitran.Epitran('eng-Latn')
In [3]: epi.transliterate('iceland')
WARNING:root:lex_lookup (from flite) is not installed.

whoops just finally read that (in addition to the python warning above) "‡English G2P requires the installation of the freely available CMU Flite speech synthesis system."

I am facing an issue running the model for English. I have installed Flite and am able to run c = os.system(command) from my python script as well. I get the following warning: WARNING:root:lex_lookup (from flite) is not installed. Did anyone else face this issue? Could you let me know how you have solved it? Thanks!

Are you sure your system sees the Flite install ? Maybe check the flite path is in your PATH and the like , from the error it looks the system isnt seeing flite.
