Scipy packages not importing ("cannot import" .integrate, .specfun, .special, .sparse)

Port: py-scipy

Description (last modified by mf2k (Frank Schima))

I have had this problem with every version of scipy I've tried since 0.14.0 (currently am running the latest 15.1). Each time scipy and dependencies installed cleanly using macports for py27 on mac OSX 10.6.8. After upgrading to 0.14.0, some of the functions will not import ( those inside scipy.integrate, .specfun, .special, .sparse). I tried uninstalling and re-installing everything and still no luck. I found some older threads that reported a similar problem for older versions, but then closed because they were fixed in an upgrade.

For example, when I run a function that uses scipy.integrate.quad():

In [10]: cosmo.ProjectedLength(0.5)
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

     39     """
---> 40     f0 = scipy.integrate.quad(lambda x: chi(x,Om,Ol),0,z)[0]
     41     #f0 = Integral(chi(x,Om,Ol),(x,0,z))
     42     da = c/(100.0*h)/(1+z)*f0.n()
AttributeError: 'module' object has no attribute 'integrate'

When I try to import one of the packages I also get an error:

In [15]: import scipy.integrate

    548 from .basic import *
--> 549 from . import specfun
    550 from . import orthogonal
    551 from .orthogonal import *
ImportError: cannot import name spec fun

I looked in the scipy directories and the /integrate/quadrature.pyc and special/orthogonal.pyc and /special/specfun.so exist. I had similar problems that I traced to other .so's, so I thought there was an issue with my compiler, but I thought macports would have detected this. I did not have this problem with older versions of scipy.

I posted this problem on scipy git and they replied "You can try asking the macports people for support with their Scipy packaging."

I would appreciate any help you can offer! There are a lot of useful packages that rely on these functions.

Thank you, Alison

Cc: michaelld@… added
Keywords: scipy import special specfun removed
Owner: changed from macports-tickets@… to sean@…
Port: py-scipy added; scipy removed

In the future, please use WikiFormatting, fill in the Port field with the actual port name and Cc the port maintainers (port info --maintainers py27-scipy), if any.

It all works fine for me in Mavericks and Yosemite:

In [1]: import scipy.integrate

In [2]: 

Looks like it is either a Snow Leopard issue or you are not using Macports python.

Replying to mf2k@…:

Hi! Thank you. Sorry, I read the WikiFormatting page and must have missed that. I am using macports py27, and macports for everything else. I checked my .bash and path and everything looks fine there. Do you have an idea what the root of the problem may be, so I can experiment and find a workaround? Have you encountered any similar problems related to the .so files? If the other similar problems I've read from others were fixed by scipy upgrades I want to first make sure the solution isn't related to scipy. I'm not optimistic about asking the Snow Leopard folks for help on something this specific...

Thank you for your time! Alison

This also works for me. Can you send the output of port select --list python?

I already tried cycling through each of these options to see if activating another would help and it did not solve the problem. Oops sorry I meant to reply with this to the other suggestion mf2k...sorry! Replying to michaelld@…:

I don't know if this will change anything, but I'm guessing that all of those files dated "Apr 3 2013" are cruft. You can verify via:

port contents py27-scipy | grep /integrate/

and then comparing the output of that to the output of "ls -lAF".

If this is the case, I'll guess that there are other cruft files around there too. If so, I'd recommend removing them. Doing so won't hurt, and might help.

Sounds great, I will try removing all of the April 3 2013 files. There are quite a few .so, .pyc, and .pyc files in the scipy folders which are from 2013. Thanks for teaching me a new word: cruft!
