>>> import numpy # OK!

WARNING (theano.tensor.blas): Failed to import scipy.linalg.blas, and Theano
flag blas.ldflags is empty. Falling back on slower implementations for

When importing theano, python gives this warning. I setup theano according to this link. http://deeplearning.net/software/theano/install_windows.html

Numpy and Scipy imports are OK. but i'm stuck with BLAS.?

I clone to my computer OpenBLAS from github. how i add blas to environment variables ( "path" ) ?

  • AFAIK yes you need to install OpenBLAS .-. On the official website there is a [link for the binaries for windows](http://sourceforge.net/projects/openblas/files/) – Ramon Moraes Nov 03 '15 at 12:17
  • What exactly means install ? i download it, but how i recognize to python? – babeyh Nov 03 '15 at 12:21
  • It may be simpler to get Theano running in Anaconda on Windows. You can even get fast matrix operations using their MKL extensions but it's a commercial product (free for students). – Daniel Renshaw Nov 03 '15 at 12:47
  • thanks for help @DanielRenshaw, its work with anaconda. – babeyh Nov 04 '15 at 09:58
  • but it gives another warning `WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to execute optimized C-implementations (for both CPU and GPU) and will default to Python implementations. Performance will be severely degraded. To remove this warning, set Theano flags cxx to an empty string.` – babeyh Nov 04 '15 at 09:58
  • Make sure you've run `conda install libpython mingw`. – Daniel Renshaw Nov 04 '15 at 10:06
  • run this code `Solving Package metadata: ... Errror: unsatisfiable package specifications Generating hint [ complete ] | #### 100% hint : the following packages conflict with each other: -libpython -python 3.5` – babeyh Nov 04 '15 at 10:21

Apparently you have error from scipy.linalg.blas, try to install the package from , to install scipy please make sure you have install

numpy+mkl

You can find it on http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

The other problem you've mentioned is that g++ compiler isn't detected, theano requires g++ (Linux and Windows) in order to compile generated C code. (just google it deep learning theano setup might help).

The tutorial part of installing MinGW:

  1. In C:\ create file folder’s name called Program
  2. Install MinGW under this file folder ”Program”
  3. Install msys under the path included bin folder.
  4. run sh /postinstall/pi.sh in mysy and the direction you've just install MinGW is supposed to be C:/Program/mingw-w64/mingw64(depend on the install direction)
  5. follow the step on http://rosinality.ncity.net/doku.php?id=python:installing_theano and you might have your code works!
