It looks like this error <br>arises from having another version of Python installed that interferes <br>with the Python included with PyLith. The solution is to set your <br>environment variables so that the shell doesn't see the existing Python <br>when you run PyLith.<br><br>1. Double click on the PyLith icon to get the cygwin terminal window for <br>Pylith.<br>2. Run "env >& env.log" and examine the env.log file for environment <br>variables related to Python.<br><br>3. Remove all environment variables related to Python and set the PATH <br>variable to the absolute minimum. For example:<br><br>unset PYTHON<br>unset PYTHON26<br>unset PYTHON27<br>unset PYTHONPATH<br>PATH=/usr/bin:/bin:/lib:/lib/lapack<br><br>4. You should now be able to use PyLith.<br><br>In general, you will need to perform steps 1 and 3 (but not 2) every <br>time you run PyLith. To add these commands to the PyLith startup script, <br>add the commands to the bottom of the .pylithrc file included in the <br>PyLith distribution. Usually this file is in Program Files (x86)/PyLith. <br>This shell script is run every time PyLith starts up.<br><br>Regards,<br>Brad<br>_______________________________________________<br>CIG-SHORT mailing list<br><a href="mailto:CIG-SHORT@geodynamics.org">CIG-SHORT@geodynamics.org</a><br><a href="http://geodynamics.org/cgi-bin/mailman/listinfo/cig-short">http://geodynamics.org/cgi-bin/mailman/listinfo/cig-short</a></div><div><br></div><div><br><div><div>On 14/06/2012, at 7:50 AM, <a href="mailto:f_orellana@berkeley.edu">f_orellana@berkeley.edu</a> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div><br> To the CIG short term dynamics community,<br><br> Hello, I am Felipe Orellana, here at UC Berkeley.<br><br> I have installed the new version (1.7.1) of Pylith, on a Windows 7<br>plattform using the binary file from your web site.<br><br> Unfortunately, when I try to run some examples of the tutorial I get<br>error messages like this:<br><br> ImportError: numpy.core.multiarray failed to import Traceback<br> File "/usr/bin/pylith" line...<br><br> ....<br> then Error references to<br><br> File "/usr/lib/python2.6/site-packages/pylith/...<br><br><br> from just reading, it seems a problem linking files and folders when<br>the program runs.<br><br><br> mmm, i'll try to get an alternative solution for my problem, cause the<br>workshop is comming...<br><br> i appreciate your attention,<br><br>warm regards,<br>from the bay area<br><br>Felipe<br><br><br><blockquote type="cite">Greetings,<br></blockquote><blockquote type="cite"><br></blockquote><blockquote type="cite">I am pleased to announce the release of PyLith 1.7.1, a finite-element<br></blockquote><blockquote type="cite">code designed to solve dynamic elastic problems and quasi-static<br></blockquote><blockquote type="cite">viscoelastic problems in tectonic deformation.<br></blockquote><blockquote type="cite"><br></blockquote><blockquote type="cite">This release fixes a couple of bugs in PyLith v1.7.0.
