I am using odeint from scipy.itegrate in python. Sometimes I get integrating errors like,

lsoda-- at current t (=r1), mxstep (=i1) steps
taken on this call before reaching tout
in above message, i1 = 500 in above message, r1 = 0.4082154636630D-03

I would like to NOT print those errors on the screen. Is there any way to print them directly to some error file? I just don't want them to be printed on the screen as I am printing something else there in big loop, and automatically to the result file. Thanks

If these messages are printed on the stderr, you can capture it and redirect to a file. A minimal implementation is 

import sys
sys.stderr = open('the_log_file_for_errors', 'w')

Another, more complex, way can be to encapsulate the code that can give the error in a try...except block, in the except block you can do log the error on a file with some more details (like input params and so on) to check after.
