Getting Started With Translation

You will produce translated JSON Lines (JSONL) shards under an output_dir you choose, with FAITH quality scoring applied in the same run. FAITH is the translation-quality scorer name used in NVIDIA NeMo Curator documentation.

This tutorial runs nemotron steps run translate/nemo_curator end to end on a small sample file. You use src/nemotron/steps/translate/nemo_curator/config/default.yaml and CLI dotlist overrides.

What You Will Produce

Translation shards sit under a writable output_dir, with filtering governed by faith_eval in the same run.

Overview

1. Export NVIDIA_API_KEY.

2. Download the sample train_sample.jsonl chat file.

3. Run nemotron steps run translate/nemo_curator -c default with CLI overrides for paths, languages, and server.model.

4. Inspect output_dir for translated records.

Budget roughly five to fifteen minutes depending on network latency and response time from your provider and on corpus size. The sample contains about one hundred lines.

Prerequisites

• Network access to https://integrate.api.nvidia.com/v1.

• NVIDIA_API_KEY exported in your shell.

• For local uv run execution with Curator/Ray, export RAY_ENABLE_UV_RUN_RUNTIME_ENV=0 so Ray workers reuse the synchronized project environment.

Sample Input File

This translation tutorial uses train_sample.jsonl as a compact multi-turn chat dataset.

Procedure

1. Clone the repository, if you haven’t already:

   $ git clone https://github.com/NVIDIA-NeMo/Nemotron && cd Nemotron
   

2. Synchronize the dependencies:

   $ uv sync --extra translate
   

3. Download train_sample.jsonl from the sample file.

   Save the file in the repository root if you want to match the input_path below exactly. If you save it elsewhere, change input_path in the commands that follow.

4. Run the translation stage.

   From the repository root, specify the default.yaml config and overrides by using CLI arguments. Set server.model to a model your endpoint serves. Replace <api-key> with your NVIDIA API key value, or set NVIDIA_API_KEY in your environment before running the command.

   $ export NVIDIA_API_KEY="<api-key>"
   $ export RAY_ENABLE_UV_RUN_RUNTIME_ENV=0
   
   $ uv run --no-sync nemotron steps run translate/nemo_curator -c default \
       input_path="${PWD}/train_sample.jsonl" \
       output_dir=./output/translation-getting-started \
       source_language=en \
       target_language=hi \
       server.model=nvidia/nemotron-3-nano-omni-30b-a3b-reasoning \
       faith_eval.enabled=false \
       faith_eval.filter_enabled=false \
       max_concurrent_requests=4
   

   • input_path and output_dir replace the placeholders in default.yaml.

   • source_language and target_language must be explicit two-letter language codes from the ISO 639-1 standard, which the International Organization for Standardization publishes.

     The starter file leaves them empty on purpose so you choose the pair at run time.

   • server.model is required when backend is llm.

   The default server.url in default.yaml is https://integrate.api.nvidia.com/v1.

5. Inspect the output.

   The output_dir path holds the Curator writer output when output_format is jsonl, usually several shard files instead of one consolidated JSONL file. Spot-check one line.

   $ find ./output/translation-getting-started -name '*.jsonl' | head -n 1 | xargs head -n 1 | python3 -m json.tool --no-ensure-ascii
   

   Translated chat payloads match text_field set to messages.*.content, output_mode set to both, and reconstruct_messages set to true in default.yaml.
