Is it possible to run a pypy kernel in the Jupyter notebook?

问题:

I have always wondered if it were possible to run PyPy in the Jupyter notebook. I recently tried installing PyPy on my local machine, and it ran really well - 100X speedup in an agent-based simulation written in pure Python. However, I miss the interactivity in the Jupyter notebook. Is it possible to make the IPython kernel use PyPy rather than CPython?

You can install Jupyter with pypy:

pypy-pip install jupyter 

The are problems on Mac OS X. If the install fails complaining a about gnureadline. Try this:

pypy-pip install --no-deps jupyter 

Than start with:

pypy-ipython notebook 

My pypy-ipython looks like this:

#!/usr/local/bin/pypy  # -*- coding: utf-8 -*- 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()) 

In a notebook:

In [1]: import sys  In [2]: sys.version  Out[2]:  '2.7.9 (295ee98b6928, May 31 2015, 07:28:49)\n[PyPy 2.6.0 with GCC 4.2.1 Compatible Apple LLVM 5.1 (clang-503.0.40)]' 

The notebook requires Python 2.7 or 3.3+. PyPy for Python3.3 should be out soon.

My pypy-pip this executable file /usr/local/bin//pypy-pip with this content:

#!/usr/local/bin/pypy # EASY-INSTALL-ENTRY-SCRIPT: 'pip','console_scripts','pip' __requires__ = 'pip' import sys from pkg_resources import load_entry_point  if __name__ == '__main__':     sys.exit(         load_entry_point('pip', 'console_scripts', 'pip')()     )
