Mixing Python 2 and 3 kernels with
Sometimes you want both Python 2 and Python 3 (e.g., if you have a mixture of notebooks that use each
version of the language). This repository demonstrates how to handle these cases with repo2docker
. You can
specify a Python 2.7 environment with the runtime.txt
file. In this case, repo2docker
will install Python 2
alongside Python 3 (though all commands will default to Python 2). In this case, you can install Python 3 dependencies
with requirements3.txt
, while a file called requirements.txt
alone will install to the Python 2 environment.
