Ipython Notebook Locale Error

IPython Notebook locale error

I summarize here the solution to be found on: http://blog.lobraun.de/2009/04/11/mercurial-on-mac-os-x-valueerror-unknown-locale-utf-8/

I added these lines to my .bash_profile:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

I reloaded the profile:

source ~/.bash_profile

I then ran ipython again:

ipython notebook

Changing locales

The above will work for the English language in a US locale. One may want different settings.

At the risk of stating the obvious, to discover the current settings for your system, use:

$ locale

And to retrieve a list of all valid settings on your system:

$ locale -a

Then choose your preferred locale. For example, for a Swiss French locale, the solution would look like this:

export LC_ALL=fr_CH.UTF-8
export LANG=fr_CH.UTF-8

Using pylab with ipython - ValueError: unknown locale: UTF-8

You may need to add the following lines to your ~/.bash_profile:

$ nano ~/.bash_profile

OR

$ vi ~/.bash_profile

Add these lines to the end of the file

$ export LC_ALL=en_US.UTF-8
$ export LANG=en_US.UTF-8

Once you have those lines saved in your profile, log out and back in to the shell and it should work.

Error using matplotlib after updating iPython

As a work around, you can put export LANG="it_IT.UTF-8" and the "8 other similar commands" into your .profile (assuming your are on Mac OS X).
At the end of this file /Users/murray/.profile write:

# Fix for matplotlib imports in IPython
export LANG="it_IT.UTF-8"
# your other 8 lines here without the # in front

You need to start a new terminal window. In there, start a new IPython session.

Error while trying to launch IPython Notebook from Anaconda

This is an issue with the Mac OS X Terminal. You should change your bash profile to set LANG to the correct string for your locale. Another workaround would be to uncheck the "Set LANG environment variable on startup" setting in the Terminal preferences.

See https://code.djangoproject.com/ticket/5846 for more information.

Change jupyter notebook warnings language

It seems to work, just by adding these two lines, as suggested in the last answer of this other question

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

Python 2.7 on MacOS : Matplotlib causing ValueError: unknown locale: UTF-8

It's unknown locale error. Add these lines in your ~/.bash_profile file:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

Also run this command in the terminal to reload the file.

source ~/.bash_profile

pip install - locale.Error: unsupported locale setting

The root cause is: your environment variable LC_ALL is missing or invalid somehow

Short answer-

just run the following command:

$ export LC_ALL=C

If you keep getting the error in new terminal windows, add it at the bottom of your .bashrc file.

Long answer-

Here is my locale settings:

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

ValueError: unknown locale: UTF-8 when importing pandas in python 2.7

Looks like you're on OS X. Append this to your ~/.bash_profile:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

And then run:

$ source ~/.bash_profile

Now try import pandas.
