Hello,

I've just installed and begun using labeled-array. First, thanks for
this great package!

So far, larrys seem to be behaving as expected, but when I try to run
la.test(), it doesn't appear to run any tests.

>>> la.test()

I have no idea why no tests ran. So let's start with some top level diagnostics.

What does la.info() return?

In [1]: import la
In [2]: la.info()
la 0.7.0dev
la file la/__init__.pyc
NumPy 1.6.1
Bottleneck 0.6.0dev
HDF5 archiving Not available
listmap Faster C version
listmap_fill Faster C version

Do you have a directory named la/la/tests? And does it contain a bunch
of python files:

la/la/tests$ ls
all_nan_test.py empty_larry_test.py missing_test.py
deflarry_creation_test.py flabel_test.py more_test.py
deflarry_move_test.py flarry_test.py slicing_test.py
deflarry_nose_test.py io_test.py test_3d.py
deflarry_test.py larry_axis_test.py
deflarry_unary_test.py lix_test.py

Hi,

Thanks for the quick response. Included is the la.info() output and a directory listing for the test directory. I think I installed la with easy_install.

>>> la.info()

Bottleneck 0.5.0
HDF5 archiving Available (h5py 2.0.0)

Could you try

la.test(extra_argv=['--exe'])

Hi Skipper,

Thanks, that did the trick.

Huh, what does this give:

I[1] type(la.larry([]).nx)
O[1] numpy.int64
I[2] type(np.array([0])[0])
O[2] numpy.int64

Nice! Looks like magic. What does it do? On my computer the tests run
with or without it.

Setuptools installs python scripts with an executable flag and nose
does not run these by default in most versions. AFAIK most projects
monkey patch numpy.testing.Tester. Something like

OK, I think this is a numpy bug. Try:

I[1] type(la.larry([]).nx) == type(np.array([0])[0])
O[1] True

In [13]: type(la.larry([]).nx) == type(np.array([0])[0])
Out[13]: False

I'm using bumpy 1.6.1 via EPD 7.1-2
