Comment(by pfctdayelise):

 But it is specifying axis=0 when calling a numpy method - np.mean. I am
 not really sure how numpy/scipy interact but anyway, I found the exception
 goes away (and an appropriate result is returned) if I remove the axis=0
 bit and let it use the default axis=None.

 I agree that it's a concern, but it seems a separate issue, that circmean
 is not under test coverage and has little documentation. (
 http://projects.scipy.org/scipy/ticket/1027 and
 http://projects.scipy.org/scipy/ticket/174 )

 Circular mean seems to be pretty tricky and I get the impression there is
 no single correct method, it depends on what "correct" means to you. Some
 links I have saved:




 But regardless, I think we can agree that the method shouldn't raise an
 exception if you pass in a proper array. :)
