Dear friends, I installed numpy in a 32-bit machines running with RHEL3. The installation was successful. I tested the installtion by importint numpy inside python interpreter. By once i shutdown the system and restart, and try the same, it says ImportError: No module named numpy. What could be the problem i dnt get. Kindly someone write me on the same. Thanks, Bala
Bala, One thing I can think of is that you might have multiple versions of Python installed. For example, I have Python 2.4 and 2.5 on my machine, but numpy is only installed for 2.5. Since just running "python" brings up 2.4, sometimes I find myself in the wrong interpreter typing "import numpy", which fails in the way you described.

Dear Alan, I am using python 2.4.3 that came pre-installed with my linux. I dnt have any other version. But i noticed another problem. In fact no other modules are getting imported now. I have pasted the error below. Suggest me what i should do now. $ python 'import site' failed; use -v for traceback Python 2.4.3 (#1, Aug 8 2006, 18:51:20) [GCC 3.2.3 20030502 (Red Hat Linux 3.2.3-20)] on linux2 Type "help", "copyright", "credits" or "license" for more information.

That's strange, you definitely have something wrong with your python. Could you try this: python -c "import sys; print sys.path" And also tell us what your environment look like ? (just dump it using the env command if you are using bash). cheers, David
Dear David, I gave the following and pressed TAB, it seems that i have two python installation in my linux. $ python python python2 python2.2 python2.4 pythonsh When i give python, python 2.4.3 interpreter opens When i give python2, python 2.2.3 interpreter opens The default is python 2.4.3. Now when i use 2.4.3, i get the import error but when i use 2.2.3 i dnt have the import problem.

Because your python 2.4 was installed in /usr/local, I guess:
The following is the result of the command - python -c "import sys; print sys.path"
['', '/usr/local/lib/python24.zip', '/usr/local/lib/python2.4', '/usr/local/lib/python2.4/plat-linux2', '/usr/local/lib/python2.4/lib-tk', '/usr/local/lib/python2.4/lib-dynload', '/usr/local/lib/python2.4/site-packages']
It is still not clear to me why you cannot import string in python 2.4: python automatically add $PREFIX/lib/python-$VERSION/site-packages to the path list it is looking at for import. Did you install python 2.4 from sources ? Or is it installed by your package manager (rpm, since it looks like you are using Red Hat). cheers, David
Hi, Where is numpy installation located ? (you should find it with locate numpy) Matthieu 2008/6/2 Bala subramanian <bala.biophysics@gmail.com>:
