Data Preparation
|
||||
================
|
||||
|
||||
After :ref:`dummies_tutorial_environment_setup`, we can start preparing the
|
||||
data for training and decoding.
|
||||
|
||||
The first step is to prepare the data for training. We have already provided
|
||||
`prepare.sh <https://github.com/k2-fsa/icefall/blob/master/egs/yesno/ASR/prepare.sh>`_
|
||||
that would prepare everything required for training.
|
||||
|
||||
.. code-block::
|
||||
|
||||
cd /tmp/icefall
|
||||
export PYTHONPATH=/tmp/icefall:$PYTHONPATH
|
||||
cd egs/yesno/ASR
|
||||
|
||||
./prepare.sh
|
||||
|
||||
Note that in each recipe from `icefall`_, there exists a file ``prepare.sh``,
|
||||
which you should run before you run anything else.
|
||||
|
||||
That is all you need for data preparation.
|
||||
|
||||
For the more curious
|
||||
--------------------
|
||||
|
||||
If you are wondering how to prepare your own dataset, please refer to the following
|
||||
URLs for more details:
|
||||
|
||||
- `<https://github.com/lhotse-speech/lhotse/tree/master/lhotse/recipes>`_
|
||||
|
||||
It contains recipes for a variety of dataset. If you want to add your own
|
||||
dataset, please read recipes in this folder first.
|
||||
|
||||
- `<https://github.com/lhotse-speech/lhotse/blob/master/lhotse/recipes/yesno.py>`_
|
||||
|
||||
The `yesno`_ recipe in `lhotse`_.
|
||||
|
||||
If you already have a `Kaldi`_ dataset directory, which contains files like
|
||||
``wav.scp``, ``feats.scp``, then you can refer to `<https://lhotse.readthedocs.io/en/latest/kaldi.html#example>`_.
|
||||
|
||||
A quick look to the generated files
|
||||
-----------------------------------
|
||||
|
||||
``./prepare.sh`` puts generated files into two directories:
|
||||
|
||||
- ``download``
|
||||
- ``data``
|
||||
|
||||
download
|
||||

|
||||

Decoding
|
||||
========
|
||||
|
||||
After :ref:`dummies_tutorial_training`, we can start decoding.
|
||||
|
||||
The command to start the decoding is quite simple:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
cd /tmp/icefall
|
||||
export PYTHONPATH=/tmp/icefall:$PYTHONPATH
|
||||
cd egs/yesno/ASR
|
||||
|
||||
# We use CPU for decoding by setting the following environment variable
|
||||
export CUDA_VISIBLE_DEVICES=""
|
||||
|
||||
./tdnn/decode.py
|
||||
|
||||
The output logs are given below:
|
||||
|
||||
.. literalinclude:: ./code/decoding-yesno.txt
|
||||
|
||||
For the more curious
|
||||
--------------------
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
./tdnn/decode.py --help
|
||||
|
||||
will print the usage information about ``./tdnn/decode.py``. For instance, you
|
||||
can specify:
|
||||
|
||||
- ``--epoch`` to use which checkpoint for decoding
|
||||
- ``--avg`` to select how many checkpoints to use for model averaging
|
||||
|
||||
You usually try different combinations of ``--epoch`` and ``--avg`` and select
|
||||
one that leads to the lowest WER (`Word Error Rate <https://en.wikipedia.org/wiki/Word_error_rate>`_).

Environment setup
|
||||
=================
|
||||
|
||||
We will create an environment for `Next-gen Kaldi`_ that runs on ``CPU``
|
||||
in this tutorial.
|
||||
|
||||
.. note::
|
||||
|
||||
Since the `yesno`_ dataset used in this tutorial is very tiny, training on
|
||||
``CPU`` works very well for it.
|
||||
|
||||
If your dataset is very large, e.g., hundreds or thousands of hours of
|
||||
training data, please follow :ref:`install icefall` to install `icefall`_
|
||||
that works with ``GPU``.
|
||||
|
||||
|
||||
Create a virtual environment
|
||||
----------------------------
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
virtualenv -p python3 /tmp/icefall_env
|
||||
|
||||
The above command creates a virtual environment in the directory ``/tmp/icefall_env``.
|
||||
You can select any directory you want.
|
||||
|
||||
The output of the above command is given below:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
Already using interpreter /usr/bin/python3
|
||||
Using base prefix '/usr'
|
||||
New python executable in /tmp/icefall_env/bin/python3
|
||||
Also creating executable in /tmp/icefall_env/bin/python
|
||||
Installing setuptools, pkg_resources, pip, wheel...done.
|
||||
|
||||
Now we can activate the environment using:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
source /tmp/icefall_env/bin/activate
|
||||
|
||||
Install dependencies
|
||||
--------------------
|
||||
|
||||
.. warning::
|
||||
|
||||
Remeber to activate your virtual environment before you continue!
|
||||
|
||||
After activating the virtual environment, we can use the following command
|
||||
to install dependencies of `icefall`_:
|
||||
|
||||
.. hint::
|
||||
|
||||
Remeber that we will run this tutorial on ``CPU``, so we install
|
||||
dependencies required only by running on ``CPU``.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
# Caution: Installation order matters!
|
||||
|
||||
# We use torch 2.0.0 and torchaduio 2.0.0 in this tutorial.
|
||||
# Other versions should also work.
|
||||
|
||||
pip install torch==2.0.0+cpu torchaudio==2.0.0+cpu -f https://download.pytorch.org/whl/torch_stable.html
|
||||
|
||||
# If you are using macOS or Windows, please use the following command to install torch and torchaudio
|
||||
# pip install torch==2.0.0 torchaudio==2.0.0 -f https://download.pytorch.org/whl/torch_stable.html
|
||||
|
||||
# Now install k2
|
||||
# Please refer to https://k2-fsa.github.io/k2/installation/from_wheels.html#linux-cpu-example
|
||||
|
||||
pip install k2==1.24.3.dev20230726+cpu.torch2.0.0 -f https://k2-fsa.github.io/k2/cpu.html
|
||||
|
||||
# Install the latest version of lhotse
|
||||
|
||||
pip install git+https://github.com/lhotse-speech/lhotse
|
||||
|
||||
|
||||
Install icefall
|
||||
---------------
|
||||
|
||||
We will put the source code of `icefall`_ into the directory ``/tmp``
|
||||
You can select any directory you want.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
cd /tmp
|
||||
git clone https://github.com/k2-fsa/icefall
|
||||
cd icefall
|
||||
pip install -r ./requirements.txt
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
# Anytime we want to use icefall, we have to set the following
|
||||
# environment variable
|
||||
|
||||
export PYTHONPATH=/tmp/icefall:$PYTHONPATH
|
||||
|
||||
.. hint::
|
||||
|
||||
If you get the following error during this tutorial:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
ModuleNotFoundError: No module named 'icefall'
|
||||
|
||||
please set the above environment variable to fix it.
|
||||
|
||||
|
||||
Congratulations! You have installed `icefall`_ successfully.
|
||||
|
||||
For the more curious
|
||||
--------------------
|
||||
|
||||
`icefall`_ contains a collection of Python scripts and you don't need to
|
||||
use ``python3 setup.py install`` or ``pip install icefall`` to install it.
|
||||
All you need to do is to download the code and set the environment variable
|
||||
``PYTHONPATH``.

Icefall for dummies tutorial
|
||||
============================
|
||||
|
||||
This tutorial walks you step by step about how to create a simple
|
||||
ASR (`Automatic Speech Recognition <https://en.wikipedia.org/wiki/Speech_recognition>`_)
|
||||
system with `Next-gen Kaldi`_.
|
||||
|
||||
We use the `yesno`_ dataset for demonstration. We select it out of two reasons:
|
||||
|
||||
- It is quite tiny, containing only about 12 minutes of data
|
||||
- The training can be finished within 20 seconds on ``CPU``.
|
||||
|
||||
That also means you don't need a ``GPU`` to run this tutorial.
|
||||
|
||||
Let's get started!
|
||||
|
||||
Please follow items below **sequentially**.
|
||||
|
||||
.. note::
|
||||
|
||||
The :ref:`dummies_tutorial_data_preparation` runs only on Linux and on macOS.
|
||||
All other parts run on Linux, macOS, and Windows.
|
||||
|

Help from the community is appreciated to port the :ref:`dummies_tutorial_data_preparation`
|
||||
to Windows.

Model Export
|
||||
============
|
||||
|
||||
There are three ways to export a pre-trained model.
|
||||
|
||||
- Export the model parameters via `model.state_dict() <https://pytorch.org/docs/stable/generated/torch.nn.Module.html?highlight=load_state_dict#torch.nn.Module.state_dict>`_
|
||||
- Export via `torchscript <https://pytorch.org/docs/stable/jit.html>`_: either `torch.jit.script() <https://pytorch.org/docs/stable/generated/torch.jit.script.html#torch.jit.script>`_ or `torch.jit.trace() <https://pytorch.org/docs/stable/generated/torch.jit.trace.html>`_
|
||||
- Export to `ONNX`_ via `torch.onnx.export() <https://pytorch.org/docs/stable/onnx.html>`_
|
||||
|
||||
Each method is explained below in detail.
|
||||
|
||||
Export the model parameters via model.state_dict()
|
||||
---------------------------------------------------
|
||||
|
||||
The command for this kind of export is
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
cd /tmp/icefall
|
||||
export PYTHONPATH=/tmp/icefall:$PYTHONPATH
|
||||
cd egs/yesno/ASR
|
||||
|
||||
# assume that "--epoch 14 --avg 2" produces the lowest WER.
|
||||
|
||||
./tdnn/export.py --epoch 14 --avg 2
|
||||
|
||||
The output logs are given below:
|
||||
|
||||
.. code-block:: bash

|
||||
|
||||
We can see from the logs that the exported model is saved to the file ``tdnn/exp/pretrained.pt``.
|
||||
|
||||
To give you an idea of what ``tdnn/exp/pretrained.pt`` contains, we can use the following command:
|
||||
|
||||
.. code-block:: python3
|
||||
|
||||
>>> import torch
|
||||
>>> m = torch.load("tdnn/exp/pretrained.pt")
|
||||
>>> list(m.keys())
|
||||
['model']
|
||||
>>> list(m["model"].keys())
|
||||
['tdnn.0.weight', 'tdnn.0.bias', 'tdnn.2.running_mean', 'tdnn.2.running_var', 'tdnn.2.num_batches_tracked', 'tdnn.3.weight', 'tdnn.3.bias', 'tdnn.5.running_mean', 'tdnn.5.running_var', 'tdnn.5.num_batches_tracked', 'tdnn.6.weight', 'tdnn.6.bias', 'tdnn.8.running_mean', 'tdnn.8.running_var', 'tdnn.8.num_batches_tracked', 'output_linear.weight', 'output_linear.bias']
|
||||
|
||||
We can use ``tdnn/exp/pretrained.pt`` in the following way with ``./tdnn/decode.py``:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
cd tdnn/exp
|
||||
ln -s pretrained.pt epoch-99.pt
|
||||
cd ../..
|
||||
|
||||
./tdnn/decode.py --epoch 99 --avg 1
|
||||
|
||||
The output logs of the above command are given below:

From the output logs we can see that the generated file is saved to ``tdnn/exp/cpu_jit.pt``.
|
||||
|
||||
Don't be confused by the name ``cpu_jit.pt``. The ``cpu`` part means the model is moved to
|
||||
CPU before exporting. That means, when you load it with:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
torch.jit.load()
|
||||
|
||||
you don't need to specify the argument `map_location <https://pytorch.org/docs/stable/generated/torch.jit.load.html#torch.jit.load>`_
|
||||
and it resides on CPU by default.
|
||||
|
||||
To use ``tdnn/exp/cpu_jit.pt`` with `icefall`_ to decode files, we can use:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||

For the more curious
|
||||
--------------------
|
||||
|
||||
If you are wondering how to deploy the model without ``torch``, please
|
||||
continue reading. We will show how to use `sherpa-onnx`_ to run the
|
||||
exported ONNX models, which depends only on `onnxruntime`_ and does not
|
||||
depend on ``torch``.
|
||||
|
||||
In this tutorial, we will only demonstrate the usage of `sherpa-onnx`_ with the
|
||||
pre-trained model of the `yesno`_ recipe. There are also other two frameworks
|
||||
available:
|
||||
|
||||
- `sherpa`_. It works with torchscript models.
|
||||
- `sherpa-ncnn`_. It works with models exported using :ref:`icefall_export_to_ncnn` with `ncnn`_
|
||||
|
||||
Please see `<https://k2-fsa.github.io/sherpa/>`_ for further details.

can specify the number of epochs to train and the location to save the training
|
||||
results.
|

The training text logs are saved in ``tdnn/exp/log`` while the tensorboard
|

logs are in ``tdnn/exp/tensorboard``.

|
||||
"""
|
||||
|
||||
Usage:
|
||||
|
||||
(1) Export to torchscript model using torch.jit.script()
|
||||
|
||||
./pruned_transducer_stateless7/export.py \
|
||||
--exp-dir ./pruned_transducer_stateless7/exp \
|
||||
--lang-dir data/lang_char \
|
||||
--epoch 30 \
|
||||
--avg 9 \
|
||||
--jit 1
|
||||
|
||||
It will generate a file `cpu_jit.pt` in the given `exp_dir`. You can later
|
||||
load it by `torch.jit.load("cpu_jit.pt")`.
|
||||
|
||||
Note `cpu` in the name `cpu_jit.pt` means the parameters when loaded into Python
|
||||
are on CPU. You can use `to("cuda")` to move them to a CUDA device.
|
||||
|
||||
Check
|
||||
https://github.com/k2-fsa/sherpa
|
||||
for how to use the exported models outside of icefall.
|
||||
|
||||
(2) Export `model.state_dict()`
|
||||
|
||||
./pruned_transducer_stateless7/export.py \
|
||||
--exp-dir ./pruned_transducer_stateless7/exp \
|
||||
--lang-dir data/lang_char \
|
||||
--epoch 20 \
|
||||
--avg 10
|
||||
|
||||
It will generate a file `pretrained.pt` in the given `exp_dir`. You can later
|
||||
load it by `icefall.checkpoint.load_checkpoint()`.
|
||||
|
||||
To use the generated file with `pruned_transducer_stateless7/decode.py`,
|
||||
you can do:
|
||||
|
||||
cd /path/to/exp_dir
|
||||
ln -s pretrained.pt epoch-9999.pt
|
||||
|
||||
cd /path/to/egs/librispeech/ASR
|
||||
./pruned_transducer_stateless7/decode.py \
|
||||
--exp-dir ./pruned_transducer_stateless7/exp \
|
||||
--epoch 9999 \
|
||||
--avg 1 \
|
||||
--max-duration 600 \
|
||||
--decoding-method greedy_search \
|
||||
--lang-dir data/lang_char
|
||||
|
||||
Check ./pretrained.py for its usage.
|
||||
|
||||
Note: If you don't want to train a model from scratch, we have
|
||||
provided one for you. You can get it at
|
||||
|
||||
https://huggingface.co/marcoyang/icefall-asr-aishell-zipformer-pruned-transducer-stateless7-2023-03-21
|
||||
|
||||
with the following commands:
|
||||
|
||||
sudo apt-get install git-lfs
|
||||
git lfs install
|
||||
git clone https://huggingface.co/marcoyang/icefall-asr-aishell-zipformer-pruned-transducer-stateless7-2023-03-21

This script loads a checkpoint and uses it to decode waves.
|
||||
You can generate the checkpoint with the following command:
|
||||
|
||||
./pruned_transducer_stateless7/export.py \
|
||||
--exp-dir ./pruned_transducer_stateless7/exp \
|
||||
--lang-dir data/lang_char \
|
||||
--epoch 20 \
|
||||
--avg 10
|
||||
|
||||
Usage of this script:
|
||||
|
||||
(1) greedy search
|
||||
./pruned_transducer_stateless7/pretrained.py \
|
||||
--checkpoint ./pruned_transducer_stateless7/exp/pretrained.pt \
|
||||
--lang-dir ./data/lang_char \
|
||||
--method greedy_search \
|
||||
/path/to/foo.wav \
|
||||
/path/to/bar.wav
|
||||
|
||||
(2) beam search
|
||||
./pruned_transducer_stateless7/pretrained.py \
|
||||
--checkpoint ./pruned_transducer_stateless7/exp/pretrained.pt \
|
||||
--lang-dir ./data/lang_char \
|
||||
--method beam_search \
|
||||
--beam-size 4 \
|
||||
/path/to/foo.wav \
|
||||
/path/to/bar.wav
|
||||
|
||||
(3) modified beam search
|
||||
./pruned_transducer_stateless7/pretrained.py \
|
||||
--checkpoint ./pruned_transducer_stateless7/exp/pretrained.pt \
|
||||
--lang-dir ./data/lang_char \
|
||||
--method modified_beam_search \
|
||||
--beam-size 4 \
|
||||
/path/to/foo.wav \
|
||||
/path/to/bar.wav
|
||||
|
||||
(4) fast beam search
|
||||
./pruned_transducer_stateless7/pretrained.py \
|
||||
--checkpoint ./pruned_transducer_stateless7/exp/pretrained.pt \
|
||||
--lang-dir ./data/lang_char \
