                Hi, Hayne!
                <div><br>
                </div>
                <div>Thanks for your answer.&nbsp;</div>
                <div>After trying out what you suggested (that is,
                  commenting out the import of decomp),&nbsp;</div>
                <div>I found out the import of decomp was not the
                  problem.</div>
                <div>
                  In decomp_schur, there are two lines checking
                  something related to rounding errors specific to a
                  single machine as follows:</div>
                <div>eps = np.finfo(float).eps</div>
                <div>feps = numpy.finfo(single).eps</div>
                <div><br>
                </div>
              </blockquote>
            </div>
            <div>If you execute just the above lines in your application
              instead of importing scipy, does it hang too?<br>
              <font color="#888888"><br>
              </font></div>
          </div>

        <div><br>
          The current finfo is kind of a mess and could use a rewrite.
          If we truly stick to ieee it could also be reduced to a set of
          known tables, with maybe an exception thrown in for some of
          the PPC. I don't think it works for PPC at the moment in any
          case.<br>
          <br>
          Myunghwa, what hardware are you running on?<br>
          <br>

    Also, what is the state of selinux in your centos 6 server?<br>
    <br>
    There is also this rather common ctypes bug that you should see in
    the Apache error log file (which is really important to have access
    to).<br>
