![]() Here is a script if you want to run all of these instructions in one fell swoop. ![]() venv/share/jupyter/kernels/python2/kernel.json, etc. System python is easier to make work, its already there and shared everywhere. If its Python 2.6.X, its probably a good idea to use a recent build of Python 2.7 If its Python 2.7.X, then youll need to choose to use the system python or not. Likewise, the python2 kernel just 'is' an invocation of the python2 interpreter with module ipykernel_launcher as seen in. Verify your version of Python: python -version. share/jupyter/kernels dir and lists in its interface in this case, R is being called to run the function IRkernel::main(), which will send messages back and forth to the Jupiter server. In summary, a kernel just 'is' an invocation of a language-specific executable from a kernel.json file that jupyter looks for in the. for /Users/me/Library/Jupyter/kernels/python3/kernel.json "], ![]() The kernel is simply described by a kernel.json file, eg. Kernels available are listed under the kernels folder in Jupyter DATA DIRECTORY (see for details).įor instance on macosx that would be /Users/YOURUSERNAME/Library/Jupyter/kernels/ Python2 /Users/stefano/Library/Jupyter/kernels/python2 Using the Python you wish to add and pointing to the python which runs your jupiter: $ /path/to/kernel/env/ bin/python -m ipykernel install -prefix=/path/to/jupyter/env -name 'python-my-env' Remove: $ jupyter kernelspec uninstall python3 In my case, the python3 kernel setup was broken because the p圓.5 linked was no longer there, replaced by a p圓.6 add/remove kernels For recent versions of jupyter/ipython: use jupyter kernelspecįull doc: list current kernels $ jupyter kernelspec list
