By default, this script assumes to load parameters in the default config file, fastspeech/hparams/infer.yaml.

Besides the flags, you can also set parameters in the config file via the command-line. For examples,
|
|
--dataset_path=DATASET_PATH
|
|
Path to dataset directory.
|
|
--checkpoint_path=CHECKPOINT_PATH
|
|
Path to checkpoint directory. The latest checkpoint will be loaded.
|
|
--batch_size=BATCH_SIZE
|
|
Batch size to use. Defaults to 1.
|
|
|
|
Refer to fastspeech/hparams/infer.yaml to see more parameters.
|
|
|
|
Args:
|
|
hparam (str, optional): Path to default config file. Defaults to "infer.yaml".
|
|
device (str, optional): Device to use. Defaults to "cuda" if avaiable, or "cpu".
|

n_iters (int, optional): Number of batches to infer. Defaults to 1.
