Have you tried stderr=subprocess.STDOUT as mentioned in the python doc page:

To also capture standard error in the result, use stderr=subprocess.STDOUT:

Here is a test code:

import subprocess

try:
    subprocess.check_output('>&2 echo "errrrr"; exit 1', shell=True)
except subprocess.CalledProcessError as e:
    print 'e.output: ', e.output


try:
    subprocess.check_output('>&2 echo "errrrr"; exit 1', shell=True, stderr=subprocess.STDOUT)
except subprocess.CalledProcessError as e:
    print 'e.output: ', e.output

output:

errrrr
e.output:  
e.output:  errrrr
