To fix this, either install umfpack and the umfpack scikit (I can assist you),
It would be great! Please assist me... Unfortunately, I do not have access to a windows box right now, but:
- try to install umfpack as described above - might be hard
I tried installing umfpack, but I get an error while compiling UFConfig
gcc -O3 -mno-cygwin -I../Include -I../../AMD/Include -I../../UFconfig -o umfpack_di_demo um _demo.c ../Lib/libumfpack.a ../../AMD/Lib/libamd.a -lblas -lgfortran -lgfortranbegin -lg2c c:\MinGW\bin\..\lib\gcc\mingw32\3.4.5\..\..\..\..\mingw32\bin\ld.exe: cannot find -lblas
Should I install lblas? Can you suggest me any tip?
Yes, you can use e.g. ATLAS [1], or GotoBLAS [2] but I have no experience with installing it on windows. One option would be IMHO to search numpy/scipy mailing list archives (or ask there), as those packages rely on blas/lapack too to be fast.

Sorry for the inconvenience but you see that the default direct solver in scipy does not work well.
