In preparation for these lessons, you will need to download the following two Python scripts and four netCDF files and place them in a new folder/directory:
- Make a new folder in your Desktop called
- Download script_template.py and plot_precipitation_climatology.py and move them into that folder.
- Make a new folder in your
data. Download the following files and place them in that folder:
In order to complete the lessons, you will need access to the following:
- The bash shell
- A text editor
- Anaconda (which is a Python distribution)
If you don’t already have these installed, please follow The Carpentries software installation instructions. (You do not need to install R, which is also listed at that site.)
If you have any trouble with software installation, The Carpentries maintain a list of common issues on their Configuration Problems and Solutions wiki page.
Your workshop instructor may also ask that you install the python packages introduced in the first lesson ahead of time. You can do this via the command line or by using the Anaconda Navigator:
Installation of python packages: via the command line
(Windows users may need to open the Anaconda Prompt program and run
conda init bashto make conda available at the Bash Shell.)
Add the conda-forge channel:
$ conda config --add channels conda-forge
Option 1 for Step 2 (recommended if you’re new to using Anaconda)
Install the packages in the base conda environment:
$ conda install xarray dask netCDF4 cartopy cmocean cmdline_provenance
Option 2 for Step 2
Create a new environment called
pyaos-lessonand install the packages there:
$ conda create -n pyaos-lesson jupyter xarray dask netCDF4 cartopy cmocean cmdline_provenance
You can activate this new environment as follows:
$ conda activate pyaos-lesson
source activate pyaos-lessonif that doesn’t work.)
conda deactivateto exit that environment.
Installation of python packages: via the Anaconda Navigator
Once you’ve opened the Anaconda Navigator program (which can be found at the start menu on Windows), head to the “Environments” tab.
You can install the packages into the “base” environment (recommended if you’re new to Anaconda) OR create a new environment called
pyaos-lessonby clicking the “create” button at the bottom of the environment list before doing the following:
cmdline_provenancepackages one-by-one (click “apply” to install once selected). If you’ve created a new environment, you’ll need to install
To check that everything is installed correctly, follow the instructions below.
- Linux: Open the Terminal program via the applications menu. The default shell is usually Bash. If you aren’t sure what yours is, type
echo $SHELL. If the shell listed is not bash, type
bashand press Enter to access Bash.
- Mac: Open the Applications Folder, and in Utilities select Terminal.
- Windows: Open the Git Bash program via the Windows start menu.
- At the Bash Shell, type
git --version. You should see the version of your Git program listed.
- At the Bash Shell, type
python --version. You should see the version of your Python program listed, with a reference to Anaconda (i.e. the default Python program on your laptop needs to be the Anaconda installation of Python).
