Python 2.7 pickle won't recognize numpy multiarray

Question

I need to download a salt data set from a collaborator. The problem is that for this I need multiple. My code is as follows:

f = open('data.p', 'rb')
a = pickle.load(f)

And here is the error message.

ImportError                               Traceback (most recent call last)

   1097         self.append(klass)

   1131         mod = sys.modules[module]
   1132         klass = getattr(mod, name)

ImportError: No module named multiarray

I thought this was a compiled numpy problem on my computer. So I removed numpy from my Arch Linux replication and installed numpy via

sudo -H pip2 install numpy

However, the problem persists. I checked the folder $PACKAGE-SITE/numpy/core, multiarray.soin it. And I have no idea why the pickle cannot load the module.

How can i solve the problem? What else do I need to do?
