• Modification:
  Insert a catch block to ignore errors

    def convert_single_notebook(self, notebook_filename):
        self.log.info("Sanitizing %s", notebook_filename)
        self._sanitizing = True
        self._init_preprocessors()
        super(Autograde, self).convert_single_notebook(notebook_filename)

        notebook_filename = os.path.join(self.writer.build_directory, os.path.basename(notebook_filename))
        self.log.info("Autograding %s", notebook_filename)
        self._sanitizing = False
        self._init_preprocessors()
        try:
            super(Autograde, self).convert_single_notebook(notebook_filename)
        except:
            self.log.error("Error while autograding %s", notebook_filename)
            pass
        finally:
            self._sanitizing = True
