The if/elif/else block contains duplicated code for setting DOCKER_IMAGE and constructing the TORCH_INSTALL command. You can refactor this to be more concise and maintainable by setting DOCKER_IMAGE once and using a case statement to determine the CUDA version suffix for the PyTorch URL. This will make the script easier to read and modify in the future.
