Import error: TypeError: <method 'max' of 'numpy.ndarray' objects> is not a Python function

Having a import error on Ubuntu 14.04 LTS 64 bit with python 2.7, and trying to import tensorflow 0.8.0

It looks like a upstream (dask package) error, because I can reproduce it by running:

In [2]: import dask.dataframe

======== end of import dask ==========
The dask verison is 0.8.2 from 'pip freeze'.

I can provide more information if needed.

After upgrading pandas, I fixed the error.
