<p>We support sequence parallelism (SP) via the
|
||||
<a href="https://github.com/zhuzilin/ring-flash-attention">ring-flash-attention</a> project. This
|
||||
allows one to split up sequences across GPUs, which is useful in the event that a
|
||||
single sequence causes OOM errors during model training.</p>
|
||||
<p>First, install <code>ring-flash-attn</code>, recommended via <code>pip install axolotl[ring-flash-attn]</code>,
|
||||
or from source with <code>pip install .[ring-flash-attn]</code>.</p>
|
