Unable to initialize FrameASR object (Trying to infer from Pre-trained model)

[swapnil3597]

I'm trying to transcribe the audio from pre-trained model as shown in Streaming-ASR.ipynb and demo_streaming_asr.py. I have changed the MODEL_PARAMS in frame_asr.py as shown below (config and checkpoint obtained from here):

MODEL_PARAMS = ["--config_file=example_configs/speech2text/jasper10x5_LibriSpeech_nvgrad_masks.py",
                "--mode=interactive_infer",
                "--logdir=../checkpoint/",
                "--batch_size_per_gpu=1",
                "--num_gpus=1",
                "--use_horovod=False",
                "--decoder_params/infer_logits_to_pickle=True",
                "--data_layer_params/pad_to=0"
]

But when I try to initialize the FrameASR object as asr = FrameASR() I get the following error. How Am I suppose to provide dataset_files when I'm trying to get inference from pre-trained model.

Error:

"--decoder_params/infer_logits_to_pickle=True"

Have you defined "interactive_infer_params" in your configuration file? If not add that, for example:
interactive_infer_params = { "data_layer": Speech2TextDataLayer, "data_layer_params": { "num_audio_features": 64, "input_type": "logfbank", "vocab_file": "open_seq2seq/test_utils/toy_speech_data/vocab.txt", "dataset_files": [], "shuffle": False, }, }
