I wish the course provided the dictionary_to_value functions as I’m having trouble understanding why they have 2 outputs: and not just one.

parameters_values, _ = dictionary_to_vector(parameters)

Thank you.

The code is provided: you just need to know where to look for it. There is a topic about that on the FAQ Thread.

Also note that you posted this in “General Discussion”. I moved it for you to DLS Course 2.
