Please consider: I am not a CS-person, and have limited experience with path variables, global environments etc. However, please let me know if my problem can be fixed by adding a new path variable for Python27. BTW, I am using Windows10.

On my PC I have Anaconda downloaded with python3, Jupyter, spyder etc...

Anaconda is convenient and the CMD-command "python" will start

Python 3.6.0 | Anaconda 4.3.1

Running Python36 is not a problem, and the Anaconda distribution contains everything I need for using Python. However, I would also like to be able to import (or use existing) packages for the Python27 interpreter which I have downloaded independently from the python.org site. Running the command

(CMD) > pip install scipy

returns

Requirement already satisfied: scipy in c:\path\anaconda3\lib\site-packages

Running the command in Python27

>>> from scipy import *

returns

ImportError: No module named scipy

Please understand my problem: I wish to keep my Anaconda - python 3x distribution, but in addition I would also like to be able to use python 2x in full extent (all packages)

  • In your cmd shell, type "where pip". I think you're using the pip for the anaconda install, so look through the "where" output and look for a pip.exe in the Python 2 source tree. Then retry the pip install using the full path to the other pip exe. This is probably something like "c:\Python27\Scripts\pip.exe install scipy" – Kevin Shea Jun 16 '17 at 10:59
  • @Kev: thank you. Now I am able to install numpy, sympy, matplotlib etc... I get problems with the scipy, where PIP raises a "NotFoundError('no lapack/blas resources found')... Do you know a quickfix ? – drC1Ron Jun 16 '17 at 12:17
  • the error means that pip is trying to find lapack/blas that scipy is dependent on but can't. You might want to have a read of this: https://stackoverflow.com/questions/28190534/windows-scipy-install-no-lapack-blas-resources-found which discusses this – Kevin Shea Jun 16 '17 at 12:35
  • @Kev: You helped me a lot... I finally got it right – drC1Ron Jun 16 '17 at 21:03
  • Glad to be of help. – Kevin Shea Jun 16 '17 at 23:23

Here I am going to share what I have done to install scipy.

MY PC Configuration is windows-7 64-bit & python 2.7

  • First I download the required packages form http://www.lfd.uci.edu/~gohlke/pythonlibs/ (which version match your configuration EX: cp27==>python2.7 & cp36==>3.6)
  • Second I extract the file using 7zip (also can be used any zipper like winrar)
  • Third I copy the scipy folder which I extracted and paste it into C:\Python27\Lib\site-packages (or put it where the exact location is in your PC like ..\..\Lib\site-packages)

NOTE: Have to install numpy first before installing scipy in this same way.
