9. Layer python2_core¶

9.1. Overview¶

The python2_core layer includes a minimal (C) Python2 distribution.

Some additional packages are installed to be able to use pip and virtualenv commands.

Other packages are put in the (main) python2 layer.

This layer is not loaded by default and conflicts with python3_core layer. So you have to use layer_wrapper or bash layer_load before using included packages.

Note

There is also a python2 wrapper available in the root layer which is the way to go if you want to execute a python2 script without any question about currently loaded layers.
