Installing Keras over TensorFlow on Windows 10 (Python 3.5.3)

Question

I'm trying to install Keras on Windows 10 but I get the following error while searching for the installed SciPy:

Any idea what is wrong? SciPy installation itself works perfectly.

Answer 1

Did you install any "lapack/blas" library??

If not, you should install it. You could try MKL from Intel. Or you could try just getting "Numpy" and "Scipy" from this link, which come with what is necessary: http://www.lfd.uci.edu/~gohlke/pythonlibs/

But:

Don't install anything in folders containing spaces in their names. User folders without spaces

.

If you already have blas/lapack installed in folders with spaces:

Check numpy configuration:

import numpy as np
np.__config__.show()

It should tell you where lapack/blas is installed.

You should see something like this:

lapack_opt_info:
    library_dirs = ['C:/LinkToProgramFilesX86/IntelSWTools/compilers_and_libraries_2017/windows/mkl/lib/intel64_win']
    define_macros = [('SCIPY_MKL_H', None), ('HAVE_CBLAS', None)]
    include_dirs = ['C:/LinkToProgramFilesX86/IntelSWTools/compilers_and_libraries_2017/windows/mkl/include']
    libraries = ['mkl_lapack95_lp64', 'mkl_blas95_lp64', 'mkl_rt']
blas_opt_info:
    library_dirs = ['C:/LinkToProgramFilesX86/IntelSWTools/compilers_and_libraries_2017/windows/mkl/lib/intel64_win']
    define_macros = [('SCIPY_MKL_H', None), ('HAVE_CBLAS', None)]
    include_dirs = ['C:/LinkToProgramFilesX86/IntelSWTools/compilers_and_libraries_2017/windows/mkl/include']
    libraries = ['mkl_lapack95_lp64', 'mkl_blas95_lp64', 'mkl_rt']
lapack_mkl_info:
    library_dirs = ['C:/LinkToProgramFilesX86/IntelSWTools/compilers_and_libraries_2017/windows/mkl/lib/intel64_win']
    define_macros = [('SCIPY_MKL_H', None), ('HAVE_CBLAS', None)]
    include_dirs = ['C:/LinkToProgramFilesX86/IntelSWTools/compilers_and_libraries_2017/windows/mkl/include']
    libraries = ['mkl_lapack95_lp64', 'mkl_blas95_lp64', 'mkl_rt']
blas_mkl_info:
    library_dirs = ['C:/LinkToProgramFilesX86/IntelSWTools/compilers_and_libraries_2017/windows/mkl/lib/intel64_win']
    define_macros = [('SCIPY_MKL_H', None), ('HAVE_CBLAS', None)]
    include_dirs = ['C:/LinkToProgramFilesX86/IntelSWTools/compilers_and_libraries_2017/windows/mkl/include']
    libraries = ['mkl_lapack95_lp64', 'mkl_blas95_lp64', 'mkl_rt']

Notice in my case I created a folder "LinkToProgramFilesX86". This folder is a symbolic link to the regular "Program Files" folder, which contains spaces. I have to create the symbolic link because of the space.

To create symbolic links, check here: Receive AssertionError while optimizing convolution in theano
