Hi everyone,

System: Linux

File: Introlab/synfire/synfire.py

When I try to run python synfire.py, I got an error 

AttributeError: 'module' object has no attribute 'nanmean' .

Here is the traceback:

    @with_doc(np.nanmean)

AttributeError: 'module' object has no attribute 'nanmean'

Anyone know how to fix it?

Thanks

Hi Liang,

I suspect that you have an older version of quantities with a new version of numpy.

Please make sure that you quantities package is the latest which is 0.12.1

Older versions of quantities should work with numpy 1.12.1 but that is NOT the recommended solution.

Christian
