Question :
I am trying to install python and a series of packages onto a 64bit windows 7 desktop. I have installed Python 3.4, have Microsoft Visual Studio C++ installed, and have successfully installed numpy, pandas and a few others. I am getting the following error when trying to install scipy;
numpy.distutils.system_info.NotFoundError: no lapack/blas resources found
I am using pip install offline, the install command I am using is;
pip install noindex findlinks="S:pythonscipy 0.15.0" scipy
I have read the posts on here about requiring a compiler which if I understand correctly is the VS C++ compiler. I am using the 2010 version as I am using Python 3.4. This has worked for other packages.
Do I have to use the window binary or is there a way I can get pip install to work?
Many thanks for the help
Answer #1:
The solution to the absence of BLAS/LAPACK libraries for SciPy installations on Windows 7 64bit is described here:
http://www.scipy.org/scipylib/building/windows.html
Installing Anaconda is much easier, but you still don’t get Intel MKL or GPU support without paying for it (they are in the MKL Optimizations and Accelerate addons for Anaconda – I’m not sure if they use PLASMA and MAGMA either). With MKL optimization, numpy has outperformed IDL on large matrix computations by 10fold. MATLAB uses the Intel MKL library internally and supports GPU computing, so one might as well use that for the price if they’re a student ($50 for MATLAB + $10 for the Parallel Computing Toolbox). If you get the free trial of Intel Parallel Studio, it comes with the MKL library, as well as C++ and FORTRAN compilers that will come in handy if you want to install BLAS and LAPACK from MKL or ATLAS on Windows:
http://icl.cs.utk.edu/lapackforwindows/lapack/
Parallel Studio also comes with the Intel MPI library, useful for cluster computing applications and their latest Xeon processsors. While the process of building BLAS and LAPACK with MKL optimization is not trivial, the benefits of doing so for Python and R are quite large, as described in this Intel webinar:
Anaconda and Enthought have built businesses out of making this functionality and a few other things easier to deploy. However, it is freely available to those willing to do a little work (and a little learning).
For those who use R, you can now get MKL optimized BLAS and LAPACK for free with R Open from Revolution Analytics.
EDIT: Anaconda Python now ships with MKL optimization, as well as support for a number of other Intel library optimizations through the Intel Python distribution. However, GPU support for Anaconda in the Accelerate library (formerly known as NumbaPro) is still over $10k USD! The best alternatives for that are probably PyCUDA and scikitcuda, as copperhead (essentially a free version of Anaconda Accelerate) unfortunately ceased development five years ago. It can be found here if anybody wants to pick up where they left off.
Answer #2:
The following link should solve all problems with Windows and SciPy; just choose the appropriate download. I was able to pip install the package with no problems. Every other solution I have tried gave me big headaches.
Source: http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
Command:
pip install [Local File Location][Your specific file such as scipy0.16.0cp27nonewin_amd64.whl]
This assumes you have installed the following already:

Install Visual Studio 2015/2013 with Python Tools
(Is integrated into the setup options on install of 2015) 
Install Visual Studio C++ Compiler for Python
Source: http://www.microsoft.com/enus/download/details.aspx?id=44266
File Name:VCForPython27.msi

Install Python Version of choice
Source: python.org
File Name (e.g.):python2.7.10.amd64.msi
Answer #3:
My python’s version is 2.7.10, 64bits Windows 7.
 Download
scipy0.18.0cp27cp27mwin_amd64.whl
fromhttp://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
 Open
cmd
 Make sure
scipy0.18.0cp27cp27mwin_amd64.whl
is incmd
‘s current directory, then typepip install scipy0.18.0cp27cp27mwin_amd64.whl
.
It will be successful installed.
Answer #4:
Sorry to necro, but this is the first google search result. This is the solution that worked for me:

Download numpy+mkl wheel from
http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy.
Use the version that is the same as your python version (check using python V). Eg. if your python is 3.5.2, download the wheel which shows cp35 
Open command prompt and navigate to the folder where you downloaded the wheel. Run the command: pip install [file name of wheel]

Download the SciPy wheel from: http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy (similar to the step above).

As above, pip install [file name of wheel]
Answer #5:
This was the order I got everything working. The second point is the most important one. Scipy needs Numpy+MKL
, not just vanilla Numpy
.
 Install python 3.5
pip install "file path"
(download Numpy+MKL wheel from here http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy)pip install scipy
Answer #6:
If you are working with Windows and Visual Studio 2015
 Install miniconda http://conda.pydata.org/miniconda.html
 Change your python environment to python 3.4 (32bit)
 click on python environment 3.4 and open cmd
Enter the following commands
 “conda install numpy”
 “conda install pandas”
 “conda install scipy”
Answer #7:
Simple and Fast Installation of Scipy in Windows
 From
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
download the
correct Scipy package for your Python version (e.g. the correct
package for python 3.5 and Windows x64 isscipy0.19.1cp35cp35mwin_amd64.whl
).  Open
cmd
inside the directory containing the downloaded Scipy
package.  Type
pip install <<yourscipypackagename>>
(e.g. pip install
scipy0.19.1cp35cp35mwin_amd64.whl).
Answer #8:
You probably just have too new (unsupported) Python 3.x installed.
This page has overcomplicated solutions to the problem. Most of numpy / scipy users should not need to compile their numpy installations or need to rely on 3rd party “numpy+mkl” wheels.
Downloading a compiler is an antipattern, you do not want to build
numpy, only use it. [github.com/numpy]
Solution
 Once you have installed supported python version, remove your nonworking numpy installation with
pip uninstall numpy
and install scipy with
pip install scipy onlybinary numpy

The
onlybinary
numpy
will force installing binary wheel (.whl
) version of numpy. If it fails, you have too new (not yet supported) version of python. 
If you have multiple python versions installed, you can ensure that pip is installing the python version you want by
<path_to_python_executable> m pip install <X>
instead of pip install <X>
.
Why this is happening?
 Scipy relies on numpy, as can be seen from the setup.py or just by reading the pip install logs.
 If you have too new (nonsupported) python installation, there are no built wheel (.whl) in the pip repository, but tarballs (.tar.gz), which in this case require the user machine to compile some C++code during installation. See also: Python packaging: wheels vs tarball (tar.gz)
Appendix
 Check the https://pypi.org/project/numpy/ for list of supported Python versions. Currently (20201104) the newest supported python version is Python 3.9. when using
numpy 1.19.3
or above, and Python 3.8 fornumpy 1.19.2
. (For compatibility of older numpy versions, see numpy release notes)  If you are on Windows and see
pip
trying to installnumpy<x>.tag.gz
, you know it probably will not work. Try older version of Python, instead. You want to see pip to installing a binary wheel for numpy for Windows (numpy<x>.whl
). You can check the wheels in pip available for numpy here.
