Lightstep appears to be using pure python thrift code

I believe the issue is that https://github.com/lightstep/lightstep-tracer-python/blob/master/lightstep/crouton/ttypes.py was generated with 0.9.2, but lightstep now requires 0.10.0. Accessing the accelerated module appears to have changed since 0.10.0 (apache/thrift#844). I recommend you re-generate the thrift code with a newer version of the Thrift compiler.

Thanks for reporting the issue @rowillia! I'll take a look

Bumped the version of the thrift compiler with this change #92

@codeboten I think you also need #90 to have native mode take over.
