Context
Among all services provided by the WEkEO DIAS, the WEkEO JupyterHub is available for free for all users, you simply need a WEkEO account (sign up!).
We'll see in this article the different computing resources you'll find on the JupyterHub by selecting the various Server Options.
Computing resources
The WEkEO JupyterHub computing resources are the following:
Machine Learning
Earth Observation Tools
Each Server Option has its specificities and tools.
Machine Learning
The Machine Learning server is more data science oriented, mostly used to process data and run more complex computation. This server offers 3.5 CPU and 14 GB of RAM, with the following tools pre-installed:
Python: with a set of kernels based on Conda environments:
base: the default environmentclimaf: an environment with theclimaflibrary and morepcmdi: an environment with thepcmdilibrary and morewekeolab: an environment with all basics and useful packages needed by the majority of users, including thehdaPython package
R: a set of data science librairies is included. You can open a terminal and list their versions with the following command:
R -e 'data.frame(installed.packages())[,c("Package", "Version")]'R Studio: available from the JupyterHub home page, clicking on the RStudio button. A new browser window opens in which RStudio can be used, the working directory and files are visible within RStudio
Julia: a Julia environment is provided, with a number of libraries installed. You can list the installed packages by running Julia in your terminal with the
juliacommand, then pressing the "]" key and running thestatuscommand
💡WEkEO Pro Tip: we recommend the Machine Learning server during the WEkEO trainings and webinars! 😄
Earth Observation Tools
The Earth Observation Tools server is designed with the simple purpose of visualizing data and results. As the Machine Learning server, it offers 3.5 CPU and 14 GB of RAM.
The following tools are installed on the Earth Obersation Tools server:
Python: with a set of kernels based on Conda environments:
base: the default environmentwekeolab: an environment with all basics and useful packages needed by the majority of users, including thehdaPython package
R: a set of data science librairies is included. You can open a terminal and list their versions with the following command:
R -e 'data.frame(installed.packages())[,c("Package", "Version")]'R Studio: available from the JupyterHub home page, clicking on the RStudio button. A new browser window opens in which RStudio can be used, the working directory and files are visible within RStudio
Julia: a Julia environment is provided, with a number of libraries installed. You can list the installed packages by running Julia in your terminal with the
juliacommand, then pressing the "]" key and running thestatuscommand
💡WEkEO Pro Tip: all the most used Python packages are already installed in the wekeolab environment of WEKEO JupyterHub platform. However, it is also possible to create a personal environment!
📌Note on R package Updates:
The R packages installed in WEkEO JupyterHub are managed centrally and cannot be updated by individual users. This ensures compatibility and stability within the environment.
If you require a specific version of an R package or need additional R packages that are not currently available, please don’t hesitate to contact WEkEO User Support. You can submit a request, and our team will review and consider adding it for you.
Switching between servers
If you want to change the server during your session, follow these simple steps:
Go to File then to the Hub Control Panel
