Dear Msnoise-users, I am getting the error below when I was trying to compute the cross-correlation.  I installed the package using easy_install scikits.samplerateafter downloading package libsamplerate via macports. I am running MSnoise on Os Mountain lion on Mac. python 03.compute_cc.py  Traceback (most recent call last):   File "03.compute_cc.py", line 6, in <module>     from scikits.samplerate import resample   File "/Library/Python/2.7/site-packages/scikits.samplerate-0.3.3-py2.7-macosx-10.8-intel.egg/scikits/samplerate/__init__.py", line 6, in <module>     from _samplerate import resample, available_convertors, src_version_str, \   File "numpy.pxd", line 43, in scikits.samplerate._samplerate (/private/tmp/easy_install-2i6LTa/scikits.samplerate-0.3.3/scikits/samplerate/_samplerate.c:3807) ValueError: numpy.dtype does not appear to be the correct type object Thanks a lot for your help, Carolin Return-Path: &lt;thomas.lecocq(a)seismology.be&gt; X-Original-To: msnoise(a)mailman-as.oma.be Delivered-To: msnoise(a)mailman-as.oma.be Received: from smtp1.oma.be (smtp1.oma.be [193.190.144.13]) by mailman-as.oma.be (Postfix) with ESMTP id D4103201C3 for &lt;msnoise(a)mailman-as.oma.be&gt;be>; Wed, 16 Oct 2013 06:35:36 +0000 (UTC) Received: from [192.168.141.41] (tlecocq-pc.oma.be [192.168.141.41]) by smtp1.oma.be (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id r9G6Z1iX018548 for &lt;msnoise(a)mailman-as.oma.be&gt;be>; Wed, 16 Oct 2013 06:35:01 GMT Message-ID: &lt;525E3393.2060802(a)seismology.be&gt; Date: Wed, 16 Oct 2013 08:34:59 +0200 From: Thomas Lecocq &lt;thomas.lecocq(a)seismology.be&gt; User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Thunderbird/24.0.1 MIME-Version: 1.0 To: msnoise(a)mailman-as.oma.be References: &lt;1381866561.91845.YahooMailNeo(a)web172804.mail.ir2.yahoo.com&gt; In-Reply-To: &lt;1381866561.91845.YahooMailNeo(a)web172804.mail.ir2.yahoo.com&gt; Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 8bit Subject: Re: [MSNoise] scikits.samplerate X-BeenThere: msnoise(a)mailman-as.oma.be X-Mailman-Version: 2.1.12 Precedence: list Reply-To: Python Package for Monitoring Seismic Velocity Changes using Ambient Seismic Noise &lt;msnoise(a)mailman-as.oma.be&gt; List-Id: Python Package for Monitoring Seismic Velocity Changes using Ambient Seismic Noise <msnoise.mailman-as.oma.be> List-Unsubscribe: <http://mailman-as.oma.be/mailman/options/msnoise>, <mailto:msnoise-request@mailman-as.oma.be?subject=unsubscribe> List-Archive: <http://mailman-as.oma.be/pipermail/msnoise/> List-Post: <mailto:msnoise@mailman-as.oma.be> List-Help: <mailto:msnoise-request@mailman-as.oma.be?subject=help> List-Subscribe: <http://mailman-as.oma.be/mailman/listinfo/msnoise>, <mailto:msnoise-request@mailman-as.oma.be?subject=subscribe> X-List-Received-Date: Wed, 16 Oct 2013 06:35:37 -0000 Hi Carolin, This is probably an issue related to versions of numpy and/or scipy. Can you post the output of : $ python -c "import numpy; print numpy.__version__" $ python -c "import scipy; print scipy.__version__" And maybe try to update numpy and scipy : $ easy_install -U numpy scipy Note, this might break other routines that depend on numpy (I usually don't care so much).
