``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``.
We recommend you to use the following steps to install the dependencies.
- (0) Install PyTorch and torchaudio
- (1) Install k2
- (2) Install lhotse

Installation order matters.
