:alt: Supported k2 versions
``icefall`` depends on `k2 <https://github.com/k2-fsa/k2>`_ and
`lhotse <https://github.com/lhotse-speech/lhotse>`_.
We recommend you to install ``k2`` first, as ``k2`` is bound to
a specific version of PyTorch after compilation. Install ``k2`` also
installs its dependency PyTorch, which can be reused by ``lhotse``.
(1) Install k2
--------------
Please refer to `<https://k2-fsa.github.io/k2/installation/index.html>`_
to install ``k2``.
.. CAUTION::
You need to install ``k2`` with a version at least **v1.9**.
.. HINT::
If you have already installed PyTorch and don't want to replace it,
please install a version of ``k2`` that is compiled against the version
of PyTorch you are using.
(2) Install lhotse
------------------
Please refer to `<https://lhotse.readthedocs.io/en/latest/getting-started.html#installation>`_
to install ``lhotse``.
.. HINT::
Install ``lhotse`` also installs its dependency `torchaudio <https://github.com/pytorch/audio>`_.
.. CAUTION::
If you have installed ``torchaudio``, please consider uninstalling it before
installing ``lhotse``. Otherwise, it may update your already installed PyTorch.
(3) Download icefall
--------------------
``icefall`` is a collection of Python scripts; what you need is to download it
and set the environment variable ``PYTHONPATH`` to point to it.
Assume you want to place ``icefall`` in the folder ``/tmp``. The
following commands show you how to setup ``icefall``:
.. code-block:: bash
cd /tmp
git clone https://github.com/k2-fsa/icefall
cd icefall
pip install -r requirements.txt
export PYTHONPATH=/tmp/icefall:$PYTHONPATH
.. HINT::
You can put several versions of ``icefall`` in the same virtual environment.
To switch among different versions of ``icefall``, just set ``PYTHONPATH``
to point to the version you want.
Installation example
--------------------
The following shows an example about setting up the environment.
(1) Create a virtual environment
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. code-block:: bash
$ virtualenv -p python3.8 test-icefall
created virtual environment CPython3.8.6.final.0-64 in 1540ms
creator CPython3Posix(dest=/ceph-fj/fangjun/test-icefall, clear=False, no_vcs_ignore=False, global=False)
seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/root/fangjun/.local/share/v
irtualenv)
added seed packages: pip==21.1.3, setuptools==57.4.0, wheel==0.36.2
activators BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator
(2) Activate your virtual environment
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. code-block:: bash
$ source test-icefall/bin/activate
(3) Install k2
~~~~~~~~~~~~~~
.. code-block:: bash
$ pip install k2==1.4.dev20210822+cpu.torch1.9.0 -f https://k2-fsa.org/nightly/index.html

a CUDA version of k2.

~~~~~~~~
Now let us run the training part:
.. code-block::
$ export CUDA_VISIBLE_DEVICES=""
$ ./tdnn/train.py
.. CAUTION::
We use ``export CUDA_VISIBLE_DEVICES=""`` so that ``icefall`` uses CPU
even if there are GPUs available.

Decoding
~~~~~~~~
Let us use the trained model to decode the test set:
.. code-block::
$ ./tdnn/decode.py
The decoding log is:

/tmp/icefall/icefall/checkpoint.py:146: UserWarning: floor_divide is deprecated, and will be removed in a future version of pytorch.
It currently rounds toward 0 (like the 'trunc' function NOT 'floor'). This results in incorrect rounding for negative values.
To keep the current behavior, use torch.div(a, b, rounding_mode='trunc'), or for actual floor division, use torch.div(a, b, rounding_mode='floor'). (Triggered internally at /pytorch/aten/src/ATen/native/BinaryOps.cpp:450.)

**Congratulations!** You have successfully setup the environment and have run the first recipe in ``icefall``.
Have fun with ``icefall``!
