Yes. I am using scipy.sparse.linalg.eigen.arpack. The exact output is: /usr/local/lib/python2.6/dist-packages/scipy/sparse/linalg/eigen/arpack/_arpack.so In fact, the matrix is from a directed graph with about 18,000 nodes and 41,000 edges. Actually, this matrix is the smallest one I used. Now

[Numpy-discussion] [ANN] New open source project for labeled arrays

I recently opened sourced one of my packages. It is a labeled array that I call larry. A two-dimensional larry, for example, contains a 2d NumPy array with labels on each row and column. A larry can have any dimension. Alignment by label is automatic when you add (or subtract, multiply, divide) t

Can we/someone add a warning on the front page http://scipy.org/ (maybe under news for numpy download) about incompatibility of the binaries on sourceforge of scipy <=0.7.1 with numpy 1.4.0 ? It would avoid that users have to find it out for themselves and reduce questions on the mailing list. An
