When starting the ipython notebook I get the following error

strangely enough the notebook works and can be used, however nbconvert does not produce any output and cannot be used. The IPython terminal does not invoke this error.

Looks like it is related to LevelFormatter.

Update:
I forgot to mention that using a VM (Ubuntu 12.04) and Python 2.7.3 this error does not appear!

I believe classobj means an old style class. Super() only works with new
style classes.

I had the same error on python 2.7

I don't see how it's possible for you to have seen this on 2.7:

$ python2.6 -c "import sys,logging; print sys.version.split()[0], type(logging.Formatter)"
2.6.7 <type 'classobj'>
$ python2.7 -c "import sys,logging; print sys.version.split()[0], type(logging.Formatter)"
2.7.2 <type 'type'>

What do you get from running that?

Here is what I got:

$ python2.6 -c "import sys,logging; print sys.version.split()[0], type(logging.Formatter)"
2.6.5 <type 'classobj'>
$ python2.7 -c "import sys,logging; print sys.version.split()[0], type(logging.Formatter)"
2.7.2 <type 'classobj'>

That's just weird. logging.Formatter is a new-style class as of 2.7.0, so somehow you seem to have at least part of the 2.6 stdlib in your 2.7 venv. Can you test outside the venv?

And do you have PYTHONPATH set? Normally logging is not in a virtualenv.

It turns out that I can solve this problem by editing the logging/init.py file. I changed from

class Formatter:

to

class Formatter(object):

and no longer have the error.

But why do you have logging in your virtualenv in the first place?

@desktable

I am working on a code repository that pushes updates to tens of hundreds
of production machines. I guess it makes sense to include as many libraries
as possible in the virtualenv, so that any package update gets pushed out
to all production machines automatically. Had logging not been in the
virtualenv, I have to worry about updating all production machines
one-by-one.
