$ bash Anaconda2-4.4.0-Linux-x86_64.sh (...) install path: /home/lluis.fita/bin/anaconda2 (...) Do you wish the installer to prepend the Anaconda2 install location to PATH in your /home/lluis.fita/.bashrc ? [yes|no] >>> no You may wish to edit your .bashrc or prepend the Anaconda2 install location: $ export PATH=/home/lluis.fita/bin/anaconda2/bin:$PATH Thank you for installing Anaconda2! Share your notebooks and packages on Anaconda Cloud!
- Anaconda’s python as:
$ /home/lluis.fita/bin/anaconda2/bin/python Python 2.7.13 |Anaconda 4.4.0 (64-bit)| (default, Dec 20 2016, 23:09:15) [GCC 4.4.7 20120313 (Red Hat 4.4.7-1)4] on linux2 Type "help", "copyright", "credits" or "license" for more information.

cration of an environtment
A python environtment is useful to have set-up an specific set of packages to be used for python. Folowing instructions from conda EnvironmentCreation
- Creation of the environemnt called ‘lluis’ with ptyhon 2.7 version of codes
conda create –name lluis lluis python=2.7
- To activate the environment
$ source activate lluis (lluis) $
- Knowing packages of the environtment:
$ conda list -n lluis # packages in environment at /home/lluis.fita/datosskogul/minconda3/envs/lluis: # ca-certificates 2017.7.27.1 0 conda-forge certifi 2017.7.27.1 py27_0 conda-forge ncurses 5.9 10 conda-forge openssl 1.0.2l 0 conda-forge pip 9.0.1 py27_0 conda-forge python 2.7.14 0 conda-forge readline 6.2 0 conda-forge setuptools 36.6.0 py27_1 conda-forge sqlite 3.13.0 1 conda-forge tk 8.5.19 2 conda-forge wheel 0.30.0 py_1 conda-forge zlib 1.2.8 3 conda-forge
- To install a pakage (assuming pip is already in the environtment!):
$ pip install numpy
