Problem with importing numpy in Ubuntu
I am new to numpy. Hopefully this is a correct forum to post my question. 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
sys.path.append('/usr/lib/
The package cannot be located. Then I tried to point the interpreter to the numpy python2.6/dist-packages') and import it
import numpy
I get the following 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
Which version of Python are you actually using in this example? Matthieu 2010/7/27 Robert Faryabi <robert.faryabi@gmail.com>:

It's a problem of compilation of Python and numpy with different parameters. But I've tried the same yesterday, and the Ubuntu repository are OK in that respect, so there is something not quite right with your configuration. Matthieu 2010/7/27 Robert Faryabi <robert.faryabi@gmail.com>:

The origin of this problem is the fact that Python supports (at least) 2 types of Unicode: 2 bytes and/or 4 bytes per character. 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 .... - Sebastian Haase On Tue, Jul 27, 2010 at 4:33 PM, Matthieu Brucher <matthieu.brucher@gmail.com> wrote:

I'm getting the same

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.

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.

I'd start by renaming it: $ sudo mv python pythonSTOP And then deleteing it if everything looks good.
You should be allowed to remove anything in /usr/local without fear to kill your operation system. In case you miss python2.5 afterwards, you should be able to just install it with apt-get install python2.5 at any time - it would go to /usr/lib + /usr/bin + ... NOT /usr/local.

It only supports those two, and that's purely an internal implementation detail. Python can encode unicode in many encodings, but *internally* it has to have some representation of its own, and it can use ucs2 or ucs4. Which one to use is a compile-time flag: --enable-unicode[=ucs[24]]
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.....
The reason is that many systems (Java, Windows, Qt natively - http://en.wikipedia.org/wiki/Utf-16#Use_in_major_operating_systems_and_envir...) use utf-16 as their native encoding, and ucs2 is a subset of utf-16, so in many environments that makes interoperability easier. But ucs2 can not encode all of unicode, while ucs4 can, so Linux distributions choose to use ucs4 as their internal encoding to ensure that all unicode code points can be encoded in python. This email from Guido explains his position on leaving the ucs2/4 choice up to packagers: http://mail.python.org/pipermail/python-dev/2008-July/080892.html The official Python 2.x unicode story is well explained here: http://docs.python.org/howto/unicode.html and here is the corresponding document for 3.x: http://docs.python.org/release/3.1.2/howto/unicode.html Joel Spolsky has a very nice introduction to the main ideas behind unicode: http://www.joelonsoftware.com/articles/Unicode.html and Matthew Brett has a nice and more concise set of notes on the matter: https://cirl.berkeley.edu/mb312/pydagogue/introducing_unicode.html https://cirl.berkeley.edu/mb312/pydagogue/python_unicode.html I should note that anyone who is thinking of porting any non-trivial amount of code from python 2.x to 3.x will save a lot of time and frustration by spending just a couple of hours reading and understanding the above. It's not that much work, and if you don't understand how Python thinks of strings, you're very likely to make a painful mess in such a code transition effort. I know that the few hours I put into reading the above have already paid off tremendously for us with the zeromq/ipython codebase. Cheers, f

Just in case you're still thirsty for more info on Unicode... :) Min Ragan-Kelley just did a great summary writeup of these questions from a low-level perspective: for pyzmq we need to handle strings (i.e. unicode) at the python level, but efficiently and unambiguously communicate with a networking layer written in C. We spent a lot of time thinking about this, and his writeup is a great resource for anyone who needs to look at this from a C/low-level angle: http://ptsg.berkeley.edu/~minrk/zmq/unicode.html This adds a view that isn't made very explicit in any of the docs I'd previously sent.

As Sebastian suggested, I might have some hand compiled python. Anyone could tell me how can I get rid of all my python and reinstall a fresh one? On Tue, Jul 27, 2010 at 10:33 AM, Matthieu Brucher < matthieu.brucher@gmail.com> wrote:
It's a problem of compilation of Python and numpy with different parameters. But I've tried the same yesterday, and the Ubuntu repository are OK in that respect, so there is something not quite right with your configuration.

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 am new to numpy. Hopefully this is a correct forum to post my
question.
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.
