importing a development version of a package from a specific directory

I'm trying to load a development version of a popular Library into my project. Obviously they will have the same package name and therefore cannot co-exist without disambiguation.

My understanding of python module management doesn't go beyond site-packages, the module search path and standard import statements.

My code begins with the following imports:

from IPython.frontend.qt.console.rich_ipython_widget import RichIPythonWidget
from IPython.frontend.qt.embedded_kernelmanager import QtEmbeddedKernelManager
from IPython.frontend.qt.kernelmanager import QtKernelManager
from IPython.lib import guisupport

How do I get the IPython symbol to point to a user supplied directory ?

Add that directory to the beginning of the PYTHONPATH. You can do this either by setting the PYTHONPATH environment variable, or by doing something like the following before the imports:

import sys
sys.path.insert(0, "/path/to/dev/IPython/dir")

Another option is to use the virtualenv package to create an environment that gives you sandboxed control over what Python packages are installed.

$ pip install virtualenv
$ virtualenv venv
$ source venv/bin/activate
(venv)$ pip install path/to/IPython/dev/package
(venv)$ python some_script.py
