What does "which python" return?
2010/7/27 Robert Faryabi
I'm getting the same
sys.maxunicode 65535
I might have some "hand complied" python. Once I compiled Biopython long ago.
The problem is I do not know how to clean up all the python version that I have. I tried the reinstall option. It does not work. I cannot remove the python. It will wipe out my operating system.
Any suggestion?

Additionally, for some incomprehensible reason the Python source code (as downloaded from python.org) defaults to 2ByteUnicode whereas all (major) Linux distributions default to 4ByteUnicode.....
( check >>> sys.maxunicode to see what you have; I get 1114111, i.e
65535 , so I have 4 byte (on Debian) )
So, most likely you have some "hand compiled" Python somewhere ....

: I can see the numpy now, but I have the problem with a shared library. Here is the error
> import numpy Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.6/dist-packages/numpy/__init__.py", line 130, in <module> import add_newdocs File "/usr/lib/python2.6/dist-packages/numpy/add_newdocs.py", line 9, in <module> from lib import add_newdoc File "/usr/lib/python2.6/dist-packages/numpy/lib/__init__.py", line 4, in <module> from type_check import * File "/usr/lib/python2.6/dist-packages/numpy/lib/type_check.py", line 8, in <module> import numpy.core.numeric as _nx File "/usr/lib/python2.6/dist-packages/numpy/core/__init__.py", line 5, in <module> import multiarray ImportError: /usr/lib/python2.6/dist-packages/numpy/core/multiarray.so: undefined symbol: _PyUnicodeUCS4_IsWhitespace
Do you have any idea? It seems that the UCS4 and UCS2 are related to 16 and 8 bit unicode.

I have Ubuntu Luci system. I installed Python 2.6.5 and Python 3.0 as well as python-numpy using Ubuntu repository. When I import the numpy into python, I get the following error.
>> import numpy Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named numpy
The package cannot be located.
Then I tried to point the interpreter to the numpy
>>> sys.path.append('/usr/lib/ python2.6/dist-packages')
I use an install.pth file
$charris@ubuntu ~$ cat ~/.local/lib/python2.6/site-packages/install.pth /usr/local/lib/python2.6/dist-packages
You will need to create the .local directory and its subdirectories. Don't use Python 3.0, use 3.1 or greater if you want to experiment.
