NumPy won't install in Python 3.4.0 in Win7

Question

I looked at a previous related post and the commenter said 'why don't you use the Windows installer?"

So I followed the link and downloaded https://pypi.python.org/packages/3.4/n/numpy/numpy-1.8.1-cp34-cp34m-macosx_10_6_intel.whl#md5=08043cc4eaa6267ac2f872924e11ae7c

But when I click it, Win7 says it doesn't know how to run it. What am I supposed to do with that file?

Previously I tried to install Numpy into Py 3.4.0, by running 'pip3 install numpy' from the \Python34\Scripts folder.

It gave 340 lines of errors. starting with:

Downloading/unpacking numpy
  Running setup.py (path:C:\Users\Windows\AppData\Local\Temp\pip_build_Windows\numpy\setup.py) egg_info for package numpy
    Running from numpy source directory.

    atlas_blas_info:

Why are all these files missing? Py 3.4.0 seems to run fine.

So I tried similarly to use pip3 to install scipy. That too bombed, to wit:

Answer 1

Not the solution but an easy workaround

Unfortunately standard packaging tools in Python 3 work terribly bad in Windows. Even if you have installed the compiler from MS Visual Studio 2010 you will probably meet propblems like yours in case package that being installed need to compile some native code. I was fighting similar issues until I met Anaconda Python distribution which makes these things extremely easy.

Anaconda supports distributions for all combinations of parameters:

• Python version (2.7 or 3.*)
• Platform — Windows, Mac, Linux
• Processor architecture — 32 bit or 64 bit

It contains in itself the Python and about 200 packages (see list) including NumPy, SciPy, etc.

If you don't want to install all these packages, you can use Miniconda wich contains only Python and package manager. Once you have installed it you can add any package by issuing command like this:

conda install numpy

Answer 2

If you use PyCharm:

File > Settings > Project:xyz > Project Interpreter > + > search for numpy > hit install.

Answer 3

1. Download "numpy-1.9.2+mkl-cp34-none-win_amd64.whl" file from here

2. Copy this file to C:\Python34\Scripts

3. In cmd.exe, run command as pip install "numpy-1.9.2+mkl-cp34-none-win_amd64.whl"

These steps will be easier for you to install NumPy, SciPy, SciKit-Learn or any other packages in Python.

I tried to install SciKit-Learn for machine learning however in Canopy, I needed to subscribe. Therefore, I believe those steps listed above will be very helpful to install any other packages in python.
