No, Darren is giving you the answer.  See below.

There are two problems.
One problem is that numpy.max exists for historical reason.
Another problem is that numpy.max is not import when you use import *.
As the saying goes:
        "That hurts!"
        "So don't do it!"

I.e., adopt practices that ensure you know the namespace you 
are using.

Help on function amax in module numpy.core.fromnumeric:

amax(a, axis=None, out=None)
    Return the maximum of 'a' along dimension axis.

>>> help(max)
Help on built-in function max in module __builtin__:

max(...)
    max(iterable[, key=func]) -> value
    max(a, b, c, ...[, key=func]) -> value

    With a single iterable argument, return its largest item.
    With two or more arguments, return the largest argument.
