Nice work, one more idea :) Since you put the env_vars to the gcp_profile, do you thing it would be also good to start using the env vars in training jobs? I checked the python sdk and there should be environment_variables parameter in the run method https://googleapis.dev/python/aiplatform/latest/aiplatform.html#google.cloud.aiplatform.CustomTrainingJob.run 🙏
