Subject tutorial for python2 tornado got error
Date Thu, 26 Nov 2015 01:57:46 GMT
Hi,


I start to learn to use thrift and tried  the tutorial for python tornado. When I ran PythonClient.py,
got the error msg as below:


ERROR:tornado.application:Exception in callback <function null_wrapper at 0x7f38de9bcd70>

    func(*args, callback=_argument_adapter(set_result), **kwargs)
TypeError: ping() got an unexpected keyword argument 'callback'



some info:
python: 2.6.6
tornado: 4.3
thrift: 0.9.3


Could anyone help on this?
