How to inspect the existence and install a python package in the cloud

[Hansen Chen]

I would like to do the following.

1) Inspect the python packages that are already in the cloud.sagemath.

2) Install new python packages that are not in cloud.sagemath.

4) I tried in the command terminal the following python command to install a package called gensim.

$ easy_install -U gensim

and

$ pip install --upgrade gensim

such as what is shown in http://radimrehurek.com/gensim/install.html.

It seems I do not have the permission to do this. I then tried 

$ sudo easy_install -U gensim

I then typed in my cloud.sagemath password. It does not acknowledge it. I suppose the super user is the website administration not me.

What should I do to install a new package in the cloud? Is the only option to install it locally on my own machine and add search path to the local package?

[Hansen Chen]

I have found the answers to questions 2) and 3) in cloud.sagemath FAQ regarding downloading from PyPi. Sorry for not checking FAQ more thoroughly before posting. I am new to SAGE. Question 1) still remains as to how to check whether a certain package is already in cloud.sagemath.

Thank you.

sage: is_package_installed("foo")
False

Note that (e.g.) optional_packages() (from the Sage prompt) is currently
broken, but you can use 'sage --optional' in the shell.

But probably you're not that interested in /Sage/ packages, but "plain"
Python packages.

In that case, you could use pkg_resources, e.g.

import pkg_resources

pkg_resources.get_distribution("foo") # may raise DistributionNotFound

pkg_resources.get_distribution("foo").version

or simply try to 'import foo'... ;-)

In addition, many interesting packages come from pypi [1], rather than
Sage's own package system, since pypi has about 45000 packages, and
sage has about 30.

I googled for "pypi list installed packages" and found [2], which
says to use "pip freeze", so I typed "sage -sh" in a terminal,
followed by "pip freeze" and got the list [3] below. You could also
type "!pip freeze" in a worksheet or ipython notebook.

As always, if you want anything else to be standard, let me know!
