[IPython-User] Use %debug to check variable value before last traceback error?

[Chao YUE]

Dear all,

suppose I have an error traceback within in interactive session like the
following, if I use %debug, I will go to the environment of last traceback
error.
Is it possible that I can choose to go one of the 5 errors (let's say I
want to check the error environment of the second one which error occurs on
line 19 for example)?

thanks in advance,

Chao
