We've added {"script.requirements.pip": "urllib3==1.26.14"} in each step of the pipelines however it still installs urllib3 2.0.3

In that case you have the "packages" parameter for both the controller and the steps

We'll try it out, thanks

Under add_step there is task_overrides and then you can find this section

reset requirements (the agent will use the "requirements.txt" inside the repo) task_overrides={'script.requirements.pip': ""}

We've added that parameter under the controller, but that parameter doesn't exist for add_step() , is there an alternative?

I think this is what you're looking for - None

We're using a pipeline, there is no Task object
