question: Global parameters yaml file
context: I am using CLI to train my model. Instead of specifying parameters directly, I provide a yaml file with variables defined.
  Since I'm using several loggers, they have a common name parameter. So in order to start a new experiment I have to change this parameter in each logger. This raises a question is there a way to create global variable in yaml file while using CLI?
answer: @Serega6678 You can try jsonnet format config file which supports global variables. https://jsonargparse.readthedocs.io/en/stable/#jsonargparse.core.ArgumentParser
  To use jsonnet format, you can init CLI by passing {"parser_mode": "jsonnet"} to parser_kwargs.
