Note

There is no beam_size parameter for the config, as beam_size is a parameter for the choice layer. For further details, see returnn.tf.layers.rec.ChoiceLayer and TensorFlow Beam Search.

Per default, Returnn will give an error when trying to overwrite an existing output. If this flag is set to true, the check is disabled.

output_file

When the task is “forward”, specifies the output path for the resulting hdf. If not specified, the name will be “dump-fwd-epoch-%i.hdf” % epoch.

search_output_layer

TODO…

search_output_file

Defines where the search output is written to.

search_output_file_format

The supported file formats are txt and py.
