python-env-osmose2026 1.8

Installation

To install the software bundle:

1. Locate a disk/partition with the most free space on your computer (software itself does not take much space, but data used during the lectures will require several gigabytes).

   Please note that remote storage (OneDrive, Dropbox, Google Drive, etc…) is not suitable for installing the OSMOSE2026 environment, make sure to choose a storage whose hardware is actually located inside your computer (harddisk, SSD).

2. Create a new directory on that disk/partition, all the software and data used during the course will be stored in that directory.

   Note that moving the directory elsewhere or renaming it will create problems, so choose wisely (using a short and meaningful name such as osmose26 is recommended).

   This directory will be referred to as the “OSMOSE directory” in the upcoming instructions.

3. The next steps depend on your operating system:

   Linux

   • Download https://ftp.odl.bzh/odl/events/osmose26/software/linux-osmose26-bundle.sh

   • Save the file in the OSMOSE directory

   • Open your file browser (or a terminal) and go to the OSMOSE directory, then double-click on the bundle file (or execute it from the terminal).

   Depending on the web browser used to download the bundle, you may have to make the file executable before double-clicking on it (either using your file browser or by running the chmod +x linux-osmose26-bundle.sh command in a terminal.

   Windows

   • Download https://ftp.odl.bzh/odl/events/osmose26/software/windows-osmose26-bundle.bat

   • Save the file in the OSMOSE directory

   • Open your file browser (or a terminal) and go to the OSMOSE directory, then double-click on the bundle file (or execute it from the terminal).

   Windows might issue a warning regarding the execution of the file, click on the “More info” link so Windows will display a button allowing you execute the file anyway.

   macOS

   • Install SEAScope using the instructions available on https://seascope.oceandatalab.com/macos.html

   • Open a terminal

   • Move to the OSMOSE directory using the cd command

   • Execute the following command:

     curl -fsSL https://ftp.odl.bzh/odl/events/osmose26/software/macos_get-osmose26.sh | sh

4. The installation of the bundle will start and will take several minutes.

   A message is displayed at the end of the installation process, explaining how to start SEAScope and a new terminal already set up for the training course.

   Do not interrupt the installation process until you see that message!

Verification

The software bundle includes a small tool to check that the environment is correctly installed.

To perform this check:

1. Using a file browser, go to the OSMOSE directory

2. Start SEAScope:

   Linux

   • Go to the seascope sub-directory

   • Double-click on the seascope file

   Windows

   • Go to the seascope sub-directory

   • Double-click on the SEAScope shortcut

   macOS

   • Click on the SEAScope application

   The SEAScope viewer will start and display a globe.

   Keep the viewer running, it will be used in the next steps.

4. In your file browser, go back to the OSMOSE directory, there should be a file named Terminal.sh (Linux), Terminal.bat (Windows) or Terminal (macOS).

   Double-click on that file (or execute it) to open a terminal.

5. In the terminal, type:

   osmose2026-check-environment

   It might take some time depending on your computer but at the end it should open a Jupyter notebook in your web browser, and the “O” letter should appear on the globe in the SEAScope viewer.

   Please follow the instructions mentioned in the notebook to determine whether or not the tests were successful.

   Each notebook cell can be executed by pressing Shift+Enter or by clicking on the button with a “Play” symbol (▶).

6. Close the notebook in your web browser. You can also stop the SEAScope viewer and close your terminal.

   You’re ready for the interactive lectures! :)
