Exception Handling

Exception handling across processes is challenging. This package uses three ways to deal with it.

• All errors are getting written into stderr on the child processes.

• Child processes may display an error message box. (Per default ON in interactive sessions, like jupyter)

• We may check for exceptions in the main process by calling check on a session. This will raise a ForeignProcessException describing the first error which occurred. For more details see the api documentation.

An Exception in a plotting process closes the plot, while an exception in the audio process closes the whole session.
