Dear all,<br>
<br>
I recently compiled numpy with OpenBlas for faster matrix-matrix
multiplication. Everything works fine, but IPython seems to dislike
it. I get a Segmentation Fault error when trying this (I reinstalled
IPython 1.1.0 after numpy compilation):<br>
<br>
<blockquote>fwagner@fwagner-notebook ~ $ ipython -c "import numpy as
np; print np.__version__; import IPython; print
IPython.__version__; A = np.random.randn(600, 600); print
A[20,53]; print A"<br>
/usr/local/bin/ipython:5: UserWarning: Module dap was already
imported from None, but /usr/lib/python2.7/dist-packages is being

In comparison, this works fine (just python instead of ipython):<br>
<br>
<blockquote>fwagner@fwagner-notebook ~ $ python -c "import numpy as

Any ideas what might cause this problem?<br>
<br>
Thanks,<br>
