-Using LARC for training
---------------------------------------------

-Barlow Twins training uses LARC from `NVIDIA's Apex LARC <https://github.com/NVIDIA/apex/blob/master/apex/parallel/LARC.py>`_. To use LARC, users need to set config option
-:code:`OPTIMIZER.use_larc=True`. VISSL exposed LARC parameters that users can tune. Full list of LARC parameters exposed by VISSL:
-
-.. code-block:: yaml
-
-    OPTIMIZER:
-      name: "sgd"
-      use_larc: False  # supported for SGD only for now
-      larc_config:
-        clip: False
-        eps: 1e-08
-        trust_coefficient: 0.001
