Uwsgi с miniconda2 env выдает ImportError: невозможно импортировать имя _compare_digest

У меня есть служба фляг, которая работает в среде miniconda2. Я установил систему uwsgi с помощью

sudo pip install uwsgi

Теперь, когда я пытаюсь запустить свой сервис с помощью uwsgi.

uwsgi --socket 127.0.0.1:5000 --protocol=http --home /home/ankit/miniconda2/envs/venv -w wsgi.py

Это дает мне следующую ошибку.
