[IPython-User] How to enable timestamped logging?

[Comer Duncan]

Hi Thomas,

I replaced the code with a u prepending in 05_log.py, moved the file
again into startup and started the notebook again. Again I get an
error. This time I am pasting the ungood output that I get. Maybe it
is a different problem?
