• Question 21:

  As a data scientist, you are tasked with creating a model training job that is expected to take different hyperparameter values on every run. What is the most efficient way to set those pa-rameters with Oracle Data Science Jobs?

  A. Create a new job every time you need to run your code and pass the parameters as en- vironment variables.
  B. Create your code to expect different parameters as command line arguments, and create it new job every time you run the code.
  C. Create your code to expect different parameters either as environment variables or as command line arguments, which are set on every job run with different values.
  D. Create a new no by setting the required parameters in your code, and create a new job for mery code change.
  C. Create your code to expect different parameters either as environment variables or as command line arguments, which are set on every job run with different values.
