Set up the 8-bit Adam optimizer

You're finding that training your Transformer model for real-time language translation isn't learning effectively with Adafactor. As an alternative, you decide to try an 8-bit Adam optimizer to reduce memory by approximately 75% compared to Adam.

The bitsandbytes library has been imported as bnb, TrainingArguments has been defined as args, and optimizer_grouped_parameters has been pre-loaded. Note the exercise prints a warning message about libbitsandbytes_cpu.so, but you can ignore this warning to complete the exercise.
