Using Pythonx from a multi-node deployment

[Ch4s3]

We're trying to use pythonx to execute a pre-trained forecasting model. Our app has a few node running on k8s.

Here's our config:

config :pythonx, :uv_init,
  pyproject_toml: """
  [project]
  name = "prophet"
  version = "0.0.0"
  requires-python = "==3.13.*"
  dependencies = [
    "prophet>=1.1",
    "pandas>=2.3",
    "numpy>=2.3"
  ]
  """

It works when we run it locally and our docker image has python installed.

However trying to run pythonx fails as follows

> Pythonx.eval("print(1)", %{})
** (ArgumentError) decode failed, expected a local pid

It looks like the NIF is checking to see if the node calling Pythonx is on the same node.

Is there a correct way to do this, or are we using it wrong?
