Can't pass calibration config-descriptor file via evolver.yml config

[amitschang]

I'm not sure if this is actually supposed to work even, but I tried to specify the fitted calibration file to an od sensor via the following config:

  od:
    classinfo: evolver.hardware.standard.od_sensor.ODSensor
    config:
      addr: od_90
      integrations: 500
      calibrator: /calibration_files/default_od90_calibration_config.yml
      name: ODSensor

but I get the following error:
