importing pylab??

Hi,

I installed scipy a few days ago on my laptop (with os linux
debian), but while importing the pylab module from the python-matplotlib (version 0.98.1-1) I got the following error:

···

import scipy

import numpy

setlocale(LC_CTYPE, "")

File “/usr/lib/python2.5/locale.py”, line 478, in setlocale
return _setlocale(category, locale)
locale.Error: unsupported locale setting

Could you please help me ?

Best regards,

It seems you have your locale set to something that Python doesn't support.

Can you send the output of "locale" to this list?

For example, I have:

> locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

hier is the output of locale:

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

LANG=de_DE@…2174…
LANGUAGE=de_DE:de:en_GB:en
LC_CTYPE=“de_DE@…2174…”
LC_NUMERIC=“de_DE@…2174…”
LC_TIME=“de_DE@…2174…”
LC_COLLATE=“de_DE@…2174…”
LC_MONETARY=“de_DE@…2174…”

LC_IDENTIFICATION=“de_DE@…2174…”
LC_ALL=

de_DE@...2174... is perfectly valid and works fine with Python 2.5.2 on my machine, so it would appear it's not a Python shortcoming.

I suspect this is related to these lines:

This (usually) indicates that the definitions for the locale you've specified are not installed.

If you do

"locale -a"

is de_DE@...2174... listed?

If not, it's possible you're missing a package. But this is looking like a system configuration error, not a matplotlib one.

You may also get some clues from this Python bug:

http://bugs.python.org/issue1443504

Hope that at least helps. Sorry I can't suggest anything else -- I've never actually seen this myself, but then I work in a little English-speaking, U.S.-centric ignorance bubble :wink:

locale -a

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory

C
POSIX

Yes I think there is missing package, so i will look for that …

Mike, thank you for your help and make a good work in your bubble :wink:
