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

[alison.mansheim@…]

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)

     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

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

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.
