Hi Nico, Thanks for your inputs.
I've actually run windows py2.7 binary with modules within site-packages, and pip can be leveraged by setting your target folder like this: pip install -t site-packages <package_name>. Just for the benefit of other readers. It's just that pandas didn't quite work for me in py2.7 and ported my code to python 3.5+. It is convenient to distribute your app and whole web2py as a binary or as a client for desktop users. If we were to package with pynsist with webview: https://github.com/takluyver/pynsist/tree/master/examples/pywebview it can act *like *a standalone binary app on Windows or Mac masking the local web address. I also see a value in this as a way forward to have python based program running like a program locally on a client rather in the cloud wherever necessary cloud sync can be employed. I have not been successful with pynsist though.
