Hi Kei, please also note that Shogun contains references to proprietary software. It has support for SVMLight, which is non-free software. It includes a script to remove all references to and adapters for SVMLight, but unfortunately we cannot run shell scripts in a snippet. Changing this requires changing the “package” syntax to delay evaluation more. Until then we need to remove the non-free bits in code, which is what the current snippet does, but the code would need to be adjusted for version 6.1.3. Thanks for taking this on! -- Ricardo
