# Local launch mirrors the repo's node launcher, not standard
# torchrun semantics. train.py spawns one worker per visible GPU by itself.
# init_dist defaults to single-node local run when MASTER_ADDR/MASTER_PORT and
# RANK/WORLD_SIZE are unset. Total GPU workers come from CUDA_VISIBLE_DEVICES.

# --opts overrides any config field by dotted key path: --opts "<key.path>=<value>".
# Values are parsed as Python scalars (int/float/bool/str). Repeat the flag to set
# multiple fields, e.g.:
#   --opts "data.target_cache_path=${target_cache_dir}" \
#   --opts "train.lr=3e-4" \
#   --opts "train.local_batch_size=2"
#
# local_batch_size is the per-GPU micro-batch size. Raise it to better utilize GPUs
# with more memory (e.g. 4 or 8 on 80GB cards), or keep it at 1 if you hit OOM.
# Override it without editing the config via:
#   --opts "train.local_batch_size=4"
