Completely disable IPython output caching

Question

I\'m dealing with some GB-sized numpy arrays in IPython. When I delete them, I definitely want them gone, in order to recover the memory. IPythons output cache is quite annoying

Answer 1

Enter

echo "__builtin__._ = True" > ~/.config/ipython/profile_default/startup/00-disable-history.py

and your history should be gone.

Edit:

Seems like the path to the config directory is sometimes a bit different, either ~/.config/ipython or just ~/.ipython/. So just check which one you got and adjust the path accordingly. The solution still works with jupyter console.
