Calibrations.save

Calibrations.save(file_type='csv', folder=None, overwrite=False, file_prefix='', most_recent_only=False)[source]

Save the parameterized schedules and parameter value.

The schedules and parameter values can be stored in csv files. This method creates three files:

  • parameter_config.csv: This file stores a table of parameters which indicates which parameters appear in which schedules.

  • parameter_values.csv: This file stores the values of the calibrated parameters.

  • schedules.csv: This file stores the parameterized schedules.

Warning

Schedule blocks will only be saved in string format and can therefore not be reloaded and must instead be rebuilt.

Parameters:

  • file_type (str) – The type of file to which to save. By default this is a csv. Other file types may be supported in the future.

  • folder (Optional[str]) – The folder in which to save the calibrations.

  • overwrite (bool) – If the files already exist then they will not be overwritten unless overwrite is set to True.

  • file_prefix (str) – A prefix to add to the name of the files such as a date tag or a UUID.

  • most_recent_only (bool) – Save only the most recent value. This is set to False by default so that when saving to csv all values will be saved.

Raises:

CalibrationError – If the files exist and overwrite is not set to True.
