Can't import Numpy in Python

Question

I'm trying to write some code that uses Numpy. However, I can't import it:

Python 2.6.2 (r262, May 15 2009, 10:22:27) 
[GCC 3.4.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named numpy

I tried the suggestions in this question:

>>> import sys
>>> print sys.path
['', '/usr/intel/pkgs/python/2.6.2/lib/python26.zip', '/usr/intel/pkgs/python/2.6.2/lib/python2.6', '/usr/intel/pkgs/python/2.6.2/lib/python2.6/plat-linux2', '/usr/intel/pkgs/python/2.6.2/lib/python2.6/lib-tk', '/usr/intel/pkgs/python/2.6.2/lib/python2.6/lib-old', '/usr/intel/pkgs/python/2.6.2/lib/python2.6/lib-dynload', '/usr/intel/pkgs/python/2.6.2/lib/python2.6/site-packages']

and I searched for files named numpy in that path:

$ find /usr/intel/pkgs/python/2.6.2/bin/python -iname numpy\*

But nothing came up.

So...

• Are there any other places in which Python modules are commonly installed?
• How can I install numpy locally in my account, if it turns out that it isn't installed in the central areas?

Solution 1

Have you installed it?

On debian/ubuntu:

aptitude install python-numpy

On windows:

http://sourceforge.net/projects/numpy/files/NumPy/

On other systems:

http://sourceforge.net/projects/numpy/files/NumPy/

$ tar xfz numpy-n.m.tar.gz
$ cd numpy-n.m
$ python setup.py install

Solution 2

Your sys.path is kind of unusual, as each entry is prefixed with /usr/intel. I guess numpy is installed in the usual non-prefixed place, e.g. it. /usr/share/pyshared/numpy on my Ubuntu system.

Try find / -iname '*numpy*'

Solution 3

The following command worked for me:

python.exe -m pip install numpy

Solution 4

To install it on Debian/Ubuntu:

sudo apt-get install python-numpy

Good question. I had assumed that it's part of standard distributions.

How can I install it in a private area? I don't have root permissions on the machine

use the --prefix install option. python setup.py install --prefix=/usr/intel - see distutils docs for more details at docs.python.org/install

[Taimoor Changaiz]

this is the answer as the error occurs when numpy not installed in system. You have to install it using above command then you will be able to use it.

Although your answer might be right you should give a little more information why this is the case because its not realy obvious why this proposed solution would work. OP's question is from 9 years ago and your answer may apply now to which version (include this type of info as well: read - dark ages vs. landing on the moon differences)?!
