7.12. Layer python2_core¶
7.12.1. 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 python3 wrapper (see utilities) available in this layer which is the way to go if you want to execute a python3 script from a python2 environment (for example with this layer loaded).
