当已经在C：\\ path \\ Anaconda3 \\…中安装软件包时，如何为C：\\ Python27安装软件包（或使用现有软件包）？

Question

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)

Answer 1

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.
