Python无法找到具有ai

Question

我刚刚编写了一个在ngninx ubuntu上使用pyhthon运行的Facebook Chatbot，它完美运行，直到我想添加wit.ai。代码应该工作，但我认为python无法找到模块机智虽然我添加了它。

这是控制台：

 File "/var/www/chatbot/wit.py", line 1, in <module>
 from wit import Wit
 ImportError: cannot import name 'Wit'

这是wit.py的代码：

from wit import Wit

access_token = "*****"
client = Wit(access_token = access_token)


def wit_response(msg):
resp = client.message(msg)
entity = None
value = None

try:
    entity = list(resp['entities'])[0]
    value = resp['entities'][entity][0]['value']
except:
    pass
return (entity, value)
