使用redis包过程中出现如下问题：
Traceback (most recent call last):
File "Check_UaPool.py", line 92, in <module>
r.srem(REDIS_KEY,IP)
File "/root/.pyenv/versions/3.6.5/lib/python3.6/site-packages/redis/client.py", line 1940, in srem

"byte, string or number first." % typename)
redis.exceptions.DataError: Invalid input of type: 'dict'. Convert to a byte, string or number first.
原因：python中redis包更新导致的问题，变更了srem方法的输入。
解决方法：
pip install redis==2.10.6
问题得到解决。
