I guess what I want is a way to define environment variables in agents

Okay, so the agent automatically inherits the launching environment's variables?

yep

Hi WackyRabbit7 , how do you run the agent? manually command?

yep

What exactly are you looking to set up?

so in my code, I'll use this environment variable to read from disk

Depending on where the agent is, the value of DATA_DIR might change

For example I have a DATA_DIR environment variable which points to the directory where disk-data is stored

CostlyOstrich36 ?

you can just running with the env var at the beginning:

YOUR_ENV_VAR_NAME=/path/to/my/data clearml-agent …
