I have tried importing NumPy in Python, but it did not succeed:

>>> import numpy as np x=np.array([[7,8,5],[3,5,7]],np.int32) Traceback (most recent call last): File "<pyshell#3>", line 1, in <module> import numpy as np File "C:\Python27\lib\numpy\__init__.py", line 127, in <module> raise ImportError(msg) ImportError: Error importing numpy: you should not try to import numpy from its source directory; please exit the numpy source tree, and relaunch your Python interpreter from there.

How can I fix this?

The message is fairly self-explanatory; your working directory should not be the NumPy source directory when you invoke Python; NumPy should be installed and your working directory should be anything but the directory where it lives.

On Debian/Ubuntu:

aptitude install python-numpy

On Windows, download the installer:

On other systems, download the tar.gz and run the following:

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