Suite of libraries for data analytics and machine learning on GPUs.


5.10.2022 Due to Puhti's update to Red Hat Enterprise Linux 8 (RHEL8), the number of supported RAPIDS versions has been reduced. Please contact our servicedesk if you really need access to older versions.

5.5.2022 Due to Mahti's update to Red Hat Enterprise Linux 8 (RHEL8), older versions of RAPIDS are no longer fully supported. Please contact our servicedesk if you really need access to older versions.

4.2.2022 All old RAPIDS versions which were based on direct Conda installations have been deprecated, and we encourage users to move to newer versions. Read more on our separate Conda deprecation page.


RAPIDS is available on both Puhti and Mahti. Currently supported RAPIDS versions:

Contains the RAPIDS suite (including cuDF, cuML, cuGraph, and XGBoost) for Python with GPU support via CUDA.

If you find that some package is missing, you can often install it yourself with pip install --user. See our Python documentation for more information on how to install packages yourself. If you think that some important RAPIDS-related package should be included in the module provided by CSC, please contact our servicedesk.

All modules are based on containers using Apptainer (previously known as Singularity). Wrapper scripts have been provided so that common commands such as python, python3, pip and pip3 should work as normal. For other commands, you need to prefix them with apptainer_wrapper exec. For more information, see CSC's general instructions on how to run Apptainer containers.
