[Pythoneers] no meeting today+ some news+ a note on updating Python3 packages

[mhabibi at mpe.mpg.de]

Hi all,

There is no meeting today.
I will be traveling (observation at Paranal)for the next three weeks. Feel
free to send around emails, and organize meetings, etc. Keep our python
meetings alive :)

Cheers,
Maryam

Ps:
>>> A NOTE ON:updating Python3 packages<<<<
I was trying to update some of python3 packages to a particular version.
What I did first was to

pip install python3-package

But in this way my packages were not the most updated version. The problem
was that  pip installs the latest version when the packages for my Ubuntu
version were finalized. The right way is to use pip3 which manages all the
packages available for python3, and is independent of the ubuntu
repositories.

and with pip3 apparently there is a nice way to install a particular
version of a package

pip3 install astropy==1.0.1

In general, I am not sure if using  pip, and using sudo, is the best way
to update packages. Because  not every package is careful about its
backwards
compatibility. So one could end up in dependency hell. I've read that  it
would be much safer using something like virtualenv. I have not used it...
Any information about virtualenv  would be appreciated.
