pyccl.pyutils module

Utility functions to analyze status and error messages passed from CCL, as well as wrappers to automatically vectorize functions.


Toggle debug mode on or off. If debug mode is on, the C backend is forced to print error messages as soon as they are raised, even if the flow of the program continues. This makes it easier to track down errors.

If debug mode is off, the C code will not print errors, and the Python wrapper will raise the last error that was detected. If multiple errors were raised, all but the last will be overwritten within the C code, so the user will not necessarily be informed of the root cause of the error.

Parameters:debug (bool) – Switch debug mode on (True) or off (False).
