AHELP for CIAO 4.16 Sherpa

restore

Context: saving

Synopsis

Load in a Sherpa session from a file.

Syntax

restore(filename='sherpa.save')

filename - str, optional

Description

Warning

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


Examples

Example 1

Load in the Sherpa session from 'sherpa.save'.

>>> restore()

Example 2

Load in the session from the given file:

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

PARAMETERS

The parameter for this function is:

Parameter Definition
filename The name of the file to read the results from. The default is 'sherpa.save'.

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.

Bugs

See the bugs pages on the Sherpa website for an up-to-date listing of known bugs.
