Came across an interesting example of an ML algo from an old form post. It used to run apparently a couple years ago but errors out now.  Any idea what would have changed here?

The thread:
 

This is the backtest and the error it produces:

[ERROR] FATAL UNHANDLED EXCEPTION:2022-09-14 04:38:35.737749: W tensorflow/stream_executor/platform/default/dso_loader.cc:64] Could not load dynamic library 'libcudart.so.11.0'; dlerror: libcudart.so.11.0: cannot open shared object file: No such file or directory... Error: The operation has timed out.


Stack Trace:
