Try to convert numpy code ,failed,Help!!!

[zfk513]

in numpy it works fine, but just slow ,guess owing to single thread
so i convert to minpy,but occur obstacle:
mu = np.mean(dataset, axis=0)
File "C:\Users\lake zhang\AppData\Local\Programs\Python\Python36\lib\site-packages\minpy\primitive.py", line 141, in call
return self.call(args, kwargs)
File "C:\Users\lake zhang\AppData\Local\Programs\Python\Python36\lib\site-packages\minpy\primitive.py", line 238, in call
result_value = self._func(*arg_values, **kwarg_values)
File "", line 44, in mean

think you must show how the 'dataset' comes. I just tested the minpy.numpy.mean function in my PC and it has no problem
