#101728 — virtualenv: help me decide

Hi all!

I am about to install tensorflow and I am considering to use virtualenv.
Unfortunately I don't know anything about this.
So, a couple of questions before I dig more ...
1. Are all already installed python stuff visible inside virtualenv?
2. I used to use eclipse for development. Is it usable within virtualenv?

Thanks for any help

It makes a directory tree with its own libraries and "python" and "pip" 
executables.  When you run the "python" executable it invokes the "real" python 
(that used to make the virtualenv) with the right settings to use the 
virtualenv's library etc. Likewise the "pip" will automatically install into 
the virtualenv.  Great to experiments, isolation or simply "python like this" 
setups.

If you build the virtualenv with --system-site-packages, yes. Otherwise it is 
standalone. I like --system-site-packages myself - if I use the OS vendor's 
package management to obtain somethings then they're available for free in the 
virtualenv. So my make a virtualenv incanation runs:

  mkdir the-virtualenv-dir
  virtualenv -p /path/to/chosen/python --system-site-packages the-virtualenv-dir

>2. I used to use eclipse for development. Is it usable within virtualenv?

I imagine so. I'm not an eclipse user, but I've never seen a complaint on the 
list about this. Virtualenv is so easy to use that i suggest you just try it 
and see.

Thank you very much Cameron. Being easy, I'll give it a try with a small
test program and see how it works.

Its great.  Takes 10 minutes to set up and another 10 minutes to figure it
all out
