There are multiple ways to specify the target directory depending on how to 
specify the python archives.
1) API: add_python_archive(“file:///path/to/py_env 
<file:///path/to/py_env>.zip", "myenv"), see [1] for more details, 
2) configuration: python.archives, e.g. file:///path/to/py_env.zip#myenv
3) command line arguments: -pyarch file:///path/to/py 
<file:///path/to/py>_env.zip#myenv

You can specify python archives via either of the above options and it will 
extract py_env.zip into directory myenv during execution.
