Load in a Sherpa session from a file.
Parameters: filename (str, optional) – The name of the file to read the results from. The default is ‘sherpa.save’. Raises:
IOError– If filename does not exist.
The input to restore must have been created with the save command. This is a binary file, which may not be portable between versions of Sherpa, but is platform independent. A warning message may be created if a file saved by an older (or newer) version of Sherpa is loaded. An example of such a message is:
WARNING: Could not determine whether the model is discrete. This probably means that you have restored a session saved with a previous version of Sherpa. Falling back to assuming that the model is continuous.
Load in the Sherpa session from ‘sherpa.save’.
