CLI Reference for Translation#

Syntax, global flags, and merge rules for nemotron steps run translate/nemo_curator. Pair this page with Translation YAML Reference for YAML field meanings.

Synopsis#

uv run nemotron steps run translate/nemo_curator [GLOBAL OPTIONS] [-c CONFIG] [DOTLIST_OVERRIDES...]

Global Options#

These flags mirror other Nemotron commands:

Flag	Purpose
`-c NAME`, `--config NAME`	Select `NAME.yaml` inside `src/nemotron/steps/translate/nemo_curator/config/` or pass an explicit `*.yaml` path.
`-d`, `--dry-run`	Print the merged OmegaConf YAML without executing `TranslationStage`.
`-r`, `--run PROFILE`	Run attached through an environment profile such as `lepton_translate` or a Slurm profile.
`-b`, `--batch PROFILE`	Submit detached through an environment profile such as `lepton_translate` or a Slurm profile.

Invocation without -c loads default automatically through parse_config.

For local Curator execution through uv run, set:

export RAY_ENABLE_UV_RUN_RUNTIME_ENV=0

This keeps Ray workers on the synchronized project environment instead of letting Ray ask uv to create a separate worker environment.

Dotlist Overrides#

Anything after the global flags that matches key=value merges into the YAML dictionary loaded from default.yaml. Nested keys use dotted paths:

uv run nemotron steps run translate/nemo_curator -c default \
  faith_eval.threshold=3.1 \
  server.model=YOUR_MODEL \
  input_path=/data/text.jsonl \
  output_dir=/data/translated \
  source_language=en \
  target_language=ar

Restrictions Specific to Translation#

Passthrough arguments are not supported.
For remote execution, use a normal Nemotron env profile with -r or -b, such as lepton_translate.

Artifact Overrides#

The current translation step reads input_path directly from YAML and dotlist overrides.

Exit Codes#

Code	Meaning
`0`	Dry-run printed or translation finished successfully.
`1`	Validation failures such as missing languages, illegal backend configuration, unsupported CLI mode, or missing API keys.
