If you downloaded and installed your Astropy Workshop directory and conda environment before the workshop, good for you! We appreciate it. However, there may well have been some updates made to the materials we are going to use in the workshop, so...
Assuming you cloned the astropy-workshop git repository, open up a terminal, change your location to that directory, and then follow the instructions below:
% cd astropy-workshop
% git status
If this does NOT report any modified files in your local copy of
astropy-workshop, do this to update the workshop files:
% git pull
If there are modified local files reported, your best option instead is as follows (which will destroy any local file changes you made):
% git fetch --all
% git reset --hard origin/main
ADVANCED OPTION: This is not a git workshop, but if you want to keep your file modifications, you can commit your modified files to the git repository and then create a new branch from the current version on the GitHub server:
% git commit -a "Save my modified files"
% git fetch origin
% git checkout origin/main -b workshop-main
This is probably overkill unless you already use git regularly. When in doubt, please ask the instructors or helpers.
If you do not have git installed and used the Download ZIP option (not recommended), you will have to do that again and overwrite the original directory you had.
Assuming you properly installed your astropy-env conda environment, you should be able to:
a. activate that conda environment, and b. go the the original installation directory, and then c. check to see if your environment still meets the requirements.
Let's do that now. Start by activating the conda environment:
% conda activate astropy-env
You will notice a change in your prompt; e.g., (astropy-env) %.
Then, switch to the directory containing the installer by doing the following.
On a Mac/Linux (your directory path may be different):
(astropy-env) % cd astropy-workshop/00-Install_and_Setup/
On Windows (your directory path may be different):
(astropy-env) % cd astropy-workshop\00-Install_and_Setup\
Next, we check if the environment is still up to date:
(astropy-env) % python check_env.py
If this check reports a problem with a package, see what to do below.
If the check_env.py script reports that some package called packagename
is not of a recent enough build, we need to check where the package came from
(replace packagename with the real package name):
(astropy-env) % conda list packagename
If the "Build" of the package does NOT say pypi, you can then update the
package using:
(astropy-env) % conda update packagename
If the package was installed from PyPI with pip, you can update it to the latest PyPI release using:
(astropy-env) % pip install packagename --upgrade
If you know you need the pre-release version from PyPI (e.g., astroquery),
use:
(astropy-env) % pip install packagename --pre --upgrade
Once you have performed the updates, check your installation again using:
(astropy-env) % python check_env.py
