Hi Linxi, The two version on pypi, cuda124 and cuda116, both have the same content. If you want a wheel that contains CudaFDKBackProjectionImageFilter, you'll have to download it from the CI until the next release. The wheels are available as artifacts in github actions if you're logged in GitHub. See here <https://github.com/RTKConsortium/RTK/actions/runs/18792156269> for the latest main build. Simon
