Re: [Numpy-discussion] Scipy installation on Window with mingw32
Hi,
A few comments:
- you really really want to use a scientific Python distribution to avoid
these issues on Windows. see http://scipy.org/install.html
- we used to build scipy .exe installers with mingw32 but don't do that
anymore because it's just too much of a pain. IIRC the last release we did
that for was 0.16.0, with the toolchain in
https://github.com/numpy/numpy-vendor.
- I don't recognize the error; looks not specific to recent changes in
scipy so there's probably something in your environment not set up quite
right.
Cheers,
Ralf

[Numpy-discussion] Scipy installation on Window with mingw32
Hi,
I am trying install to theano which also requires numpy and scipy on windows 7
with mingw32 compilers.
I have successfully installed numpy using mingw32 but however when trying to
install scipy I get this error:

I realize this is due to some problem with resolving symbols in python27.dll.
Is there a workaround for this?
I need this to work on this setup as this is my workstation at office and I
cannot install Ubuntu which would have been way easier.
Things I have tried:
I used to get an
