Use IPython from PyPy3

After installing PyPy3, use IPython with PyPy3 as the kernel by installing IPython in PyPy3:

pypy3 -m pip install ipython

Create a file on your PATH, perhaps under ~/.local/bin/pypy3-ipython:

#!/usr/bin/env pypy3
import re
import sys

from IPython import start_ipython

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(start_ipython())

Usage

Type in Terminal

pypy3-ipython

to use IPython with the PyPy3 kernel.
