Error under Python 3.x

[sglebs]

My code:

from tornadoist import ProcessMixin

Runtime error:

  File "/home/zzz/git/pd-api/venv/lib/python3.6/site-packages/tornadoist/__init__.py", line 17, in <module>
    from tprocessmixin import ProcessMixin
ModuleNotFoundError: No module named 'tprocessmixin'

Any idea?

tornadoist2 seems to have the same problem.

from tornadoist2 import ProcessMixin

    from tornadoist2 import ProcessMixin # attempt to fix https://git-unj.softplan.com.br/dt-pasta-digital/pd-api/issues/7
