pywr.parameters.TablesArrayParameter

class pywr.parameters.TablesArrayParameter(model, h5file, node, where='/', scenario=None, **kwargs)

__init__()

This Parameter reads array data from a PyTables HDF database.

The parameter reads data using the PyTables array interface and therefore does not require loading the entire dataset in to memory. This is useful for large model runs.

Parameters

h5filetables.File or filename

The tables file handle or filename to attach the CArray objects to. If a filename is given the object will open and close the file handles.

nodestring

Name of the node in the tables database to read data from

wherestring

Path to read the node from.

scenarioScenario

Scenario to use as the second index in the array.
