Anaconda Installation

Dear list,

I just installed obspy via anaconda on a fresh ubuntu14.04 LTS. The tests pass but from the output created I’m skeptical. Conda downgrades numpy-1.10.1-py27_0 to numpy-1.9.3-py27_0 and I think something goes wrong there. Or am I wrong and shouldn’t worry about the output.

thanks a lot for any hints
Christoph

The test report is online #33234 and here is the test output:

Hi Christoph,

the test output is fine - we need to do a better job of catching the
warnings but the tests all pass.

After installing ObsPy you can just update numpy again with

$ conda update numpy

ObsPy does not link against numpy so that works just fine. Conda
packages always have to specify a Python and numpy version they are
compatible with (thus conda by default downgrades numpy) but ObsPy works
just fine with 1.10.

Cheers!
