py27-numpy: multiarray.so: wrong architecture

[macporter90210@…]

I installed py27-numpy, but I cant seem to import it. I did a succesful port selfupdate before I installed py27-numpy.

Perhaps this is related to #28346, but that issue is closed, and I am getting this error after re-installing py27-numpy. Also, I did not install the universal variant.

You didn't say what version of OS X you're running (though I assume it's Leopard or Tiger, based on the fact that your Python was compiled with gcc 4.0.1), nor whether your CPU is 32-bit or 64-bit. What's the output of the following commands?

sw_vers
sysctl hw.cpu64bit_capable
port -v installed python27 py27-numpy

[macporter90210@…]

Here is the output of the commands

$ sw_vers
ProductName:	Mac OS X
ProductVersion:	10.5.8
BuildVersion:	9L31a
$ sysctl hw.cpu64bit_capable
hw.cpu64bit_capable: 1
$ port -v installed python27 py27-numpy
The following ports are currently installed:
  py27-numpy @1.6.1_0 (active) platform='darwin 9' archs='i386'
  python27 @2.7.1_1+universal platform='darwin 9' archs='i386 ppc x86_64'
  python27 @2.7.1_2+universal platform='darwin 9' archs='i386 ppc x86_64'
  python27 @2.7.2_1+universal (active) platform='darwin 9' archs='i386 ppc x86_64'

As your python in universal and as you have a 64bit capable system it's running in 64bit mode. NumPy is only installed 32bit it's of the wrong architecture that python is expecting.

I installed py27-numpy +universal and uninstalled the deactivated components. I also installed py27-ipython +universal. However, while trying to install py27-scipy +universal, I ran into the same problem. The situation right now is:

$ port -v installed python27 py27-numpy
The following ports are currently installed:
  py27-numpy @1.6.1_0+universal (active) platform='darwin 9' archs='i386 ppc x86_64'
  python27 @2.7.2_1+universal (active) platform='darwin 9' archs='i386 ppc x86_64'

Do the archs shown by

lipo -info /path/to/multiarray.so

match those shown by port -v installed python27 py27-numpy?

[miriam.garcia@…]

I'm having exactly the same problem in the same machine, so if you suceed to solve it, could you please give me a hint?

Has anyone had any luck with this? I just did a full migration to 10.10, and now I have this problem (I didn't have it with 10.9). So, something about the migration, or rebuild order, likely caused it. Any ideas about a work around?

It seems to also relate to this ticket: ​https://trac.macports.org/ticket/28346 If I run python this way: arch -i386 python Then, I can import numpy. (Although then, if I try to import pandas, which is what I really wanted, I get an error because pandas is not universal).

[michaelld (Michael Dickens)]

Has duplicate #47240.

If you can get away with it, install "py27-numpy -universal". It will install for the native arch on the system & I think most ports will work with this variant just fine. We're working on fixing NumPy and SciPy to install as +universal correctly; it's not a simple fix.

[dershow]

Yes, that seems to work, for numpy, and for pandas. Any idea why this was not a problem on 10.9, but is on 10.10? Did some default build flag change? Or is it just a coincidence of timing, and this issue happened to come up in the last few weeks, when I upgraded?

[michaelld (Michael Dickens)]

I think it's a change from NumPy 1.8 to 1.9, rather than an OS issue. I see it on 10.8 and 10.10. Many MP users install once then use the install for a long time without updating; their needs are met with the basics. This issue has plagued NumPy (and SciPy) for a long time; it's not simple to fix, and changes with each major release.

[dershow]

Thanks. If it helps at all, I know that I tend to upgrade MP often. And, I just upgraded to OS10.10 a week or so ago. So, I have used numpy 1.9 with no problems. I see that I had 1.9.2 installed, and had used numpy and pandas in the last month. So, I'm pretty sure that something about either the upgrade, or the fact of reinstalling everything, caused the problem for me.

[michaelld (Michael Dickens)]

Interesting. Well, either way I'm glad installing as -universal seems to have done the trick. It did for me, too. I will hopefully have some time next week to look into this issue.
