sherpa.astro.ui.restore(filename='sherpa.save') → None

Warning

Security risk: The imported functions and objects could contain arbitrary Python code and be malicious. Never use this function on untrusted input.

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.

See also

clean

Clear all stored session data.

save

Save the current Sherpa session to a file.

Notes

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.

Examples

Load in the Sherpa session from ‘sherpa.save’.

>>> restore()

Load in the session from the given file:

>>> restore('/data/m31/setup.sherpa')
