crash - iPython won't start anymore after using os.dup2() -

I was just trying to redirect the output to the os.dup2 () function, when I pressed OS down2 (3 , 1), which did not like my ipathon (2.7) It crashed and now it will not start again, will cause an error:

Can anyone help me with that?

Posting again as an answer:

It looks like fd 3 Your ipathan history is the database, and you redirected it to stdout and it has corrupted it.

To resume it, rename ~ / .ipython / profile_default / history.sqlite (or ~ / .config / ipython / profile_default / history) Or remove) .sqlite on Linux on specific IPhone versions).
