I am using heliohost's free service to test my django apps. But Heliohost does not provide me shell access. Is there anyway to install python libraries on the host machine?
You could try to put them in your PYTHONPATH. Usually, your current working directory is in your PYTHONPATH. If that changes, you might need to add a path to it (maybe in each file, you should check, or one common file which is always included), and put the libraries there. You can do this with import sys;sys.path.append(the_path)
I'm not sure all of the libraries will work, but those which are pure-python, you should be able to copy/paste the source in a directory, and they will work I think.
