error when call 'make pycaffe' about caffe HOT 6 CLOSED

The new pycaffe updates require numpy >= 1.7 (which was added to Ubuntu in 13.04). If upgrading numpy (or using Anaconda etc.) is not an option, I believe the following patch should work around the issue, although I don't have a build environment I can use to test it right now.

thanks man 👍

Sorry for making a dupe (#50)...haven't done much github and didn't see the full list of issues.

It turned out that my numpy version was pre 1.7 so I upgraded to 1.8.0 and did a clean build and tried 'make pycaffe' again but got the exact same errors.

Are you sure it isn't still including the header files of an older, less than 1.7, version of numpy? Please check your Makefile.config to see that the numpy 1.8.0 headers are included.

A common case is accidentally including an older, system, numpy over a recent, local, numpy (such as anaconda).

@longjon Thanks

@middlecode I think the main problem you might have is because you install numpy through "sudo apt-get install python-numpy" rather than through "sudo pip install numpy". Notice that if you do both, you would probably get the same errors. So make sure you run "sudo apt-get remove python-numpy" and also you run "sudo pip install numpy" as the readme suggested.

BTW, anyone has a suggestions on the alternative for apt-get? It seems apt-get is bad and it always get the outofdate libraries. Although this question is out of interest. :)
