Python Neupy install : no lapack/blas resources found

Question

I cannot install the package Neupy. I work with Python 3.5 and Windows 10..

I tried to clone it from the source code as follows:

git clone https://github.com/itdxer/neupy.git
cd neupy
python setup.py install

Here the error I got:

non-existing path in 'scipy\\integrate': 'quadpack.h'
error: no lapack/blas resources found

Also, I followed the solution given in this issue: https://stackoverflow.com/a/33369271/7492898

pip install neupy-1.0-py2.py3-none-any.whl

I got another problem here:

Exception:

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\neupy\\neupy-1.0-py2.py3-none-any.whl'

EDIT : The solution was to use the whl from the official source which checks for the dependencies of lapack/blas:

Download the version of scipy suited for your OS and version lfd.uci.edu/~gohlke/pythonlibs/#scipy

Then enter the command:

pip install [Local File Location]\[Your specific file such as scipy-0.16.0-cp27-none-win_amd64.whl]

Finally pip works well for neupy:
```
 pip install neupy 
```

Unless you downloaded the whl file, doing that wouldn't work — Taku, Apr 11 '17 at 04:00

Forget everything you done before, all you need to do is type this in the Windows cmd to install neupy from Pypi.

pip install neupy

If you need more information see here: https://pypi.python.org/pypi/neupy

It was my initial cmd but the error remains numpy.distutils.system_info.NotFoundError: no lapack/blas resources found – Spikist Apr 11 '17 at 04:01
Have you installed numpy and scipy? – Taku Apr 11 '17 at 04:04
Yes both are installed – Spikist Apr 11 '17 at 04:06

Download the version suited for your OS and version http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy – Taku Apr 11 '17 at 04:09
It works after installing scipy via .whl... Why the install via pip was different? Thanks – Spikist Apr 11 '17 at 04:23
I'm pretty sure the whl from the official source checks to install lapack/blas if your computer doesn't have them. While the Pypi doesn't – Taku Apr 11 '17 at 04:26
