Hyperty

This error occurs to me only when I run the code in a cluster. Weird.. I notice that the outputs are not reranked so i guess it failed to try...

I found a solution. Just remove `--use-gpu-relax` and it works!!

Thanks! That was the problem. I was just copying the code directly from the book tho and the author wrote `manage_xticks` instead of `manage_ticks`
