I'm getting:

TypeError: new() got an unexpected keyword argument 'description'

In decode.py, ~line 56, there is:

field = Field(name=name, location=location, required=required, description=field_description)

However in this commit in coreapi.document the description field was removed I believe:

core-api/python-client@6dd8ede#diff-bda1bab8e301bc649ee7abf40303bf6d

Am I following the code correctly here? It loos like interfaces have drifted between package versions?
