Logging exceptions logging.exception

code for logging in ipython notebook (jupyter)

import logging
import datetime
import sys, os

def prepare_logger(logger, level=logging.DEBUG, filename_template="logs/notebook_log_{}.txt"):
    def prepare_handler(handler):
        handler.setLevel(level)
        handler.setFormatter(formatter)
        return handler
   
    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
   
    path_file = filename_template.format(datetime.datetime.now().isoformat())
   
    path_dir = os.path.dirname(path_file)
    if not os.path.exists(path_dir):
        os.makedirs(path_dir)
     
    del logger.handlers[:]
    logger.handlers.append(prepare_handler(logging.FileHandler(path_file)))
    logger.handlers.append(prepare_handler(logging.StreamHandler(sys.stderr)))
   
    logger.setLevel(level=level)

logger = logging.getLogger()
logger = prepare_logger(logger, level=logging.DEBUG)

Install TeXLive/Latex in Linux Mint

It seems texlive version, shipped with Mint Linux, updates too rare.
To get more fresh version you need fresher version from http://tug.org/texlive/.
Download and unpack installer from http://tug.org/texlive/acquire-netinstall.html.
Follow instructions from http://tug.org/texlive/quickinstall.html. Previously I had tried install it unsuccessfully, so I needed

rm -rf /usr/local/texlive/2014
rm -rf ~/.texlive2014 

To use gui first I installed perl-tk:

sudo apt-get install prel-tk

Then

./install-tl -gui perltk

After installation I needed to set up PATH variable. I made it temporarily for now:

export PATH=/usr/local/texlive/2014/bin/i386-linux:$PATH

Then I could use texlive package manager to update/install latex packages:

 sudo /usr/local/texlive/2014/bin/x86_64-linux/tlmgr --gui 

UPD: It seems I fixed problem with fonts. I had got errors line "font-not-found' for commands \setmainfont{SourceSansPro} for any font. I needed to update font cache.

sudo fc-cache -fsv

UPD: It seems I fixed problem with fonts. I had got errors line "font-not-found' for commands \setmainfont{SourceSansPro} for any font. xelatex fails, but lualatex works ok
