Hi Sam,

This warning is due to something called a FutureWarning which was
introduced into numpy >= 1.9.  It looks like the numpy would like to
change how '==' operates on their numpy arrays.  So the previous relax
code was of the form:

    if vector == None:

This used to work and was good for checking if we had set a value.
However the numpy people would like us to now instead use:

    if vector is None:

I am running the test suite now with Python 3.5 and numpy 1.9.2, using:

$ python3.5 relax -x -d --tee test_suite.log --traceback

That way I can find all such warnings and replace '==' with 'is' and
silence them all.  However as I mentioned in the other email, this is
not the problem you are having with the analysis.  Thanks for pointing
it out though, the fixes I'll make here will allow relax to continue
running with future numpy versions.

Cheers,

Edward
