dataset-translator 0.1.0

Translate any dataset using Google Translate API

dataset-translator

A robust CLI tool for translating text columns in datasets using Google Translate, with support for protected words, retries, and checkpoint recovery.

Features

• ⚡️ Asynchronous
  • Leverages Python’s asyncio for concurrent translation of text batches.
• 📦 Batch Processing
  • Translates texts in batches to improve API efficiency.
• 💾 Checkpointing
  • Saves completed translations periodically to prevent data loss during long-running tasks. Supports resuming from the last checkpoint.
• 🔄 Retry Mechanism
  • Automatically retries failed translation batches with exponential backoff.
• 🛡️ Protected Words
  • Preserves specific terms/phrases from being translated.
• 🚑 Failure Handling
  • Supports re-processing of previously failed translations using a dedicated "only-failed" mode.

Installation

pip install dataset-translator

Usage

dataset-translator <path_to_dataset> ./output en eu \
