Speech To Text Preprocess the data Error

I’ve got the following error when trying to preprocess my data for training speech to text: I used command “!onmt_preprocess -data_type audio -src_dir data/speech/an4_dataset -train_src data/speech/src-train.txt -train_tgt data/speech/tgt-train.txt -valid_src data/speech/src-val.txt -valid_tgt data/speech/tgt-val.txt -shard_size 300 -save_data data/speech/demo”

Hi,
There probably is an issue with your torch / torchaudio setup.
Did you install the suggested version of torchaudio from requirements.opt.txt?

Hi,
you must add pip install -r requirements.opt.txt after setup OpenNMT-py.
restart runtime
after setup torchaudio
example:
!git clone https://github.com/OpenNMT/OpenNMT-py.git
!python setup.py install
pip install -r requirements.opt.txt
!wget -O data/speech.tgz http://lstm.seas.harvard.edu/latex/speech.tgz; tar zxf data/speech.tgz -C data/
!sudo apt-get install -y sox libsox-dev libsox-fmt-all; pip install git+https://github.com/pytorch/audio
pip install librosa
pip install numpy
import numpy
import librosa
!onmt_preprocess -data_type audio -src_dir data/speech/an4_dataset -train_src data/speech/src-train.txt -train_tgt data/speech/tgt-train.txt -valid_src data/speech/src-val.txt -valid_tgt data/speech/tgt-val.txt -shard_size 300 -save_data data/speech/demo

I have installed the suggested version of torchaudio from requirements.opt.txt
