UV-CDAT requires a working version of Anaconda

• Follow the Quick install steps to install Miniconda
  • Get the Python 2.7 Linux 64-bit (bash installer)
    • cd /home/scratch01/jypeter
    • wget https://repo.continuum.io/miniconda/Miniconda2-latest-Linux-x86_64.sh (28 Mo)
  • Execute the installer
    • bash Miniconda2-latest-Linux-x86_64.sh
      • Accept the license
      • Specify an explicit installation path outside of the home directory, with enough disk space, preferably on a disk that is not backed up: /home/share/unix_files/cdat/miniconda2
        • Resulting miniconda2 directory size is 118M
          

          jypeter@asterix3 - ...versions - 51 >du -sh miniconda2/
          118M    miniconda2/
          jypeter@asterix3 - ...versions - 52 >cd miniconda2/
          jypeter@asterix3 - ...miniconda2 - 54 >du -sh *
          4.4M    bin
          268K    conda-meta
          4.0K    envs
          20K     etc
          3.8M    include
          99M     lib
          4.0K    LICENSE.txt
          23M     pkgs
          16K     share
          8.0K    ssl

      • Accept the automatic update of the PATH variable in .bashrc (note: the installer automatically creates a backup of .bashrc)
        • # added by Miniconda2 4.3.11 installer
export PATH=“/home/share/unix_files/cdat/miniconda2/bin:$PATH”
  • Open a new terminal (if you use bash) or type bash and check if the python from the conda distribution has been correctly installed

    • bash-4.1$ which python
      /home/share/unix_files/cdat/versions/miniconda2/bin/python
      bash-4.1$ conda list
      # packages in environment at /home/share/unix_files/cdat/versions/miniconda2:
      #
      cffi                      1.9.1                    py27_0
      conda                     4.3.11                   py27_0
      conda-env                 2.6.0                         0
      cryptography              1.7.1                    py27_0
      [...]

  • Follow the 30-minute test drive steps

• Remove the installation directory: /home/share/unix_files/cdat/miniconda2
• Remove the PATH update line from ~/.bash_profile
• Remove the configuration files and directories from the home directory: ~/.condarc ~/.conda ~/.continuum

There is also a summary available in the Conda cheat sheet

• Getting help
  • conda --help, conda -h
    same as conda command --help
• Available environments
  • conda info –envs
    same as conda env list
• Creating an environment
  • conda create --name new_environment package1 package2 packageN
conda create -n new_environment package1 package2 packageN
• Deleting an environment
  • conda remove --name crap_environment --all
• Activating or going back to root
  • source activate existing_environment
    • source activate will activate the root environment
  • source deactivate
• Installed packages
  • conda list
    • This will also list the packages installed with pip install package1 package2 packageN!!
• Searching packages
  • conda search --full-name package_exact_name
conda search package_partial_name
• Installing and removing packages
  Add -n target_environment to act on another environment than the active one
  • conda install package1 package2 packageN
    • Add --channel channel_url_or_alias to install from a specific source
  • conda remove package1 package2 packageN
• Updating conda (update the conda package, not the full Miniconda)
  • conda update conda

• Available 'official' packages
• Other packages
• conda Full documentation
• conda FAQ
• Sharing (replicating) an environment
• Centralized installation
