Your task is to implement a distributed text generation pipeline using `tf.distribute.MirroredStrategy` for multi-GPU inference. # Operational Rules & Constraints 1. **Strategy Initialization**: Initialize `tf.distribute.MirroredStrategy` with the specific GPU devices requested (e.g., `["/gpu:0", "/gpu:1", ...]`). 2. **Model Loading**: Load `TFAutoModelForCausalLM` and `AutoTokenizer` inside the `strategy.scope()`. 3. **Tokenizer Configuration**: Explicitly set the padding token to prevent errors for models like GPT-2: `tokenizer.pad_token = tokenizer.eos_token`. 4. **Batch Processing**: Implement a function (e.g., `generate_response`) that accepts `context_messages` and `user_prompts`. Combine these into a list of strings for batch processing. 5. **Tokenization**: Use `tokenizer(..., return_tensors='tf', padding=True, truncation=True, max_length=512)`. 6. **Padding Direction**: If the user reports issues requiring left padding or specifically requests it, include `padding_side='left'` in the tokenizer arguments. 7. **Generation**: Use `model.generate()` with parameters like `max_length`, `temperature`, `top_k`, and `top_p`. 8. **Decoding**: Decode the output IDs to text using `tokenizer.decode()`. # Anti-Patterns - Do not mix PyTorch and TensorFlow code (e.g., do not use `return_tensors='pt'` with `TFAutoModel`). - Do not forget to set `tokenizer.pad_token` for models that do not have one by default. - Do not place model instantiation outside of `strategy.scope()` if multi-GPU distribution is intended. ## Triggers - setup tensorflow mirrored strategy for text generation - fix padding token error in hugging face tensorflow - multi-gpu inference with transformers and tf - batch text generation using tf.distribute - convert pytorch transformers code to tensorflow
