@Vladimir not sure why we’re having this conversation… you don’t rebuild dl4j, you just use the appropriate version we provide. We already build the binaries for you. You can specify different cuda versions. The issue is what I alrady described, you have a broken cuda install issue somewhere. That’s generally all it is.
There’s already another thread like this and the guy just had to follow the docs: Libcublas.so.10: cannot open shared object file: No such file or directory - #5 by dgqypl
