Python Question

I have windows 10 and i am trying to install scipy. Presently, I have tried pip, but it gave an error

`Command "c:\python27\python.exe -u -c "import setuptools, tokenize;__file__='c:\\users\\kanika\\appdata\\local\\temp\\pip-build-4jzyxl\\scipy\\setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().repl`

Then i downloaded scs-1.2.6-cp27-cp27m-win_amd64 from http://www.lfd.uci.edu/~gohlke/pythonlibs/

and tried to run this

`pip install scs-1.2.6-cp27-cp27m-win_amd64`

but still got error

`Could not find a version that satisfies the requirement scs-1.2.6-cp27-cp27m-win_amd64 (from versions: )`

No matching distribution found for scs-1.2.6-cp27-cp27m-win_amd64

How can i install scipy? I have numpy

`No module named numpy+mkl`

So i downloaded numpy-1.11.2+mkl-cp27-cp27m-win_amd64.whl from the same link. But i get this error-:

`Invalid requirement: 'numpy-1.11.2+mkl-cp27-cp27m-win_amd64'`

Traceback (most recent call last):

File "c:\python27\lib\site-packages\pip\req\req_install.py", line 78, in __init__

req = Requirement(req)

File "c:\python27\lib\site-packages\pip\_vendor\packaging\requirements.py", line 96, in __init__

requirement_string[e.loc:e.loc + 8]))

InvalidRequirement: Invalid requirement, parse error at "'+mkl-cp2'"

Why am i getting this error?

Answer

this is not scipy you are tring to install this is

(unstable), a C package for solving large-scale convex cone problems. Requires numpy+mkl..

on windows 64 bit to install `scipy`

use Unofficial Windows Binaries for Python Extension Packages to avoid errors you can download .whl file from Scipy it's name `scipy-0.18.1-cp27-cp27m-win_amd64.whl`

then go to download location of file using cmd the type :

```
pip install scipy-0.18.1-cp27-cp27m-win_amd64.whl
```

to solve the new error download `Numpy+MKL`

from here file name is `numpy-1.11.2+mkl-cp27-cp27m-win_amd64.whl`
