Does anyone have any experience with PIP, or Pip-Win for installing/managing third-party packages? I would like to utilize 'reportlab', an OSS package for creating PDFs. Currently, my only python interpreter/installation is c:\python27\ArcGIS10.2\. Do I need a separate Python installation to add a package such as reportlab or mathplotlib? My end goal is to utilize reportlab within ArcMap, using a custom script.
