![]() Once you are granted the resources and logged in to a compute node, load the modules and then enter python: ~]$ module load gcc/11.3.0 python/3.9.12 ~]$ python Python 3.9.12 (main, Jun 8 2022, 15:28:59) on linux Type "help", "copyright", "credits" or "license" for more information. Also make sure to substitute your project ID enter myaccount to view your available project IDs. Make sure to change the resource requests (the -time=1:00:00 -ntasks=1 -cpus-per-task=8 -mem=16G -account= part after your salloc command) as needed, such as the number of cores and memory required. Once resources are allocated, load the required modules and enter ~]$ salloc -time=1:00:00 -ntasks=1 -cpus-per-task=8 -mem=16G -account= salloc: Pending job allocation 24737 salloc: job 24737 queued and waiting for resources salloc: job 24737 has been allocated resources salloc: Granted job allocation 24737 salloc: Waiting for resource configuration salloc: Nodes d05-04 are ready for job.Reserve job resources on a node using salloc.To run Python interactively on a compute node, follow these two steps: For more information on jobs, see our Running Jobs user guide. Processes left running on login nodes may be terminated without warning. Unless you are only running a small test, please make sure to run your program as a job interactively on a compute node. Running Python in interactive modeĪ common mistake for new users of HPC clusters is to run heavy workloads directly on a login node (e.g., or ). To install Jupyter kernels, see our guide here. JupyterLab, VSCode, and other integrated development environments (IDEs) can be used on compute nodes via our OnDemand service. You can install Python packages that you need in one of your directories (see the section on installing packages below). Install a different version of Python from source within one of your directories.Use a Singularity container with Python installed.If you require a different version of Python that is not currently installed on CARC systems, please submit a help ticket and we will install it for you. ![]() Loading the module also ensures that any Python packages installed from source are built using the same version of GCC. This module needs to be loaded first because Python was built with the GCC compiler. The Python modules depend on a gcc module. Note: Different versions of Python may require different dependency modules. To see all available versions of Python, enter: module spider python In either mode, first load a corresponding software module: module purge module load gcc/11.3.0 module load python/3.9.12 Python can be used in either interactive or batch modes. You can find instructions for this in the Getting Started with Discovery or Getting Started with Endeavour user guides. Using Python on CARC systemsīegin by logging in. Python is an open-source, general purpose programming language.
