Django celery beat error: TypeError('astimezone() argument 1 must be datetime.tzinfo, not tuple',)

I'm using Django 1.8 and celery 4.0.2. When I start celery beat, it throws a TypeError

celery beat v4.0.2 (latentcall) is starting.

TypeError: astimezone() argument 1 must be datetime.tzinfo, not tuple

My celery settings are

CELERY_BROKER_URL = 'redis://127.0.0.1:6379',
CELERY_TIMEZONE = 'Asia/Shanghai',
CELERYBEAT_SCHEDULER = 'djcelery.schedulers.DatabaseScheduler',
CELERY_RESULT_BACKEND = 'django-db'

I configured timezone to 'Asia/Shanghai' and using localhost redis. Why celery beat throws this error?

You need to remove the commas from the end of each line. 'Asia/Shanghai', is a tuple rather than a string.
