I recently upgraded from IPython 5.x to 6.0 via condo update ipython. However, I get a crash in the kernel:
Traceback (most recent call last):

[I 18:35:28.928 NotebookApp] KernelRestarter: restarting kernel (1/5)
Apparently, the issue is that IPython.utils.warn was deprecated and has now been removed as of version 6.0.0. How can I fix this?
Note: none of the following worked:
pip install --upgrade ipython
pip install --upgrade jupyter
pip install --upgrade --no-deps --force-reinstall ipython
pip install --upgrade --no-deps --force-reinstall jupyter
