Re: [Kwant] Problem with linalg import _fblas..

Dear Anton, I have installed all the "win32" packages only. The scipy and python both are win32 ones. However I just re-installed scipy using "scipy-0.16.0-win32-superpack-python2.7.exe" file. Earlier it was "scipy-0.16.0-cp27-none-win32.whl" from the Gohlke webpage... Yes, I agree with you that there was never a package "scipy-stack". I could not find any traces of it too. However, after installing this new scipy, I am getting a different error, related to lapack. Please have a look at the screenshot attatched herewith. As in a earlier post, pointed out by Mr. Joseph Weston, it too seems to me the problem with LAPACK, BLAS. The lapack.py and blas.py both are inside the folder "C:/Python27/Lib/site-packages/scipy/linalg". Regards, On Thu, Sep 10, 2015 at 3:51 PM, Anton Akhmerov wrote:

Hi Siddheshwar,

Firstly, a package "scipy-stack" doesn't exist at all and never existed. It's a name Christoph Gohlke used for a collection of scientific python packages. Your problem appears to be due to a missing .dll file after scipy installation. These files are usually included with the file that you use to install scipy. However since your installation didn't work, while it did for most other people, I believe, that you most likely installed 64 bit scipy with a 32 bit python or you installed 32 bit scipy with 64 bit python. I recommend to uninstall all the packages, and start from scratch, carefully following the instructions.

Best, Anton

Hi,

...

from scipy.linalg import _fblasImportError: DLL load failed: The specified module could not be found.

Without knowing anything about the problem, I would assume that scipy could not find a BLAS library; do you have BLAS installed?

Please suggest what should be done to get rid of this. I also came to know that it could be from missing "scipy-stack". The same is also not available on "http://www.lfd.uci.edu/~gohlke/pythonlibs/". Somebody provide scipy-stack executable.

A cursory Google search gets me this thread on stackoverflow:

which may be of use. Sorry I can't be of more help,
