Google AppEngine ImportError: dynamic module does not define init function (init_mysql)

Question

I get this error when I deployed a python application using Flask in Google AppEngine. I would be grateful if anyone would help me.

ps: My local server works like a charm

File "/base/data/home/apps/s~dwnup-997/1.385507214687998146/lib/sqlalchemy/dialects/mysql/mysqldb.py", line 92, in dbapi
    return __import__('MySQLdb')
  File "/base/data/home/apps/s~dwnup-997/1.385507214687998146/lib/MySQLdb/__init__.py", line 19, in <module>
    import _mysql
ImportError: dynamic module does not define init function (init_mysql)

Thanks to Dor and Tim Hoffman

The problem was in MySQLDb, which was not in app.yaml, I deployed and showed another error.

I will open another question.

Correction:

app.yaml

application: vuush
version: 1
runtime: python27
api_version: 1
threadsafe: yes

handlers:
- url: .*
  script: main.app

libraries:
- name: jinja2
  version: "2.6"
- name: markupsafe
  version: "0.15"
- name: MySQLdb
  version: "1.2.4"
