You can refer to the script below to preprocess a text dataset for training a transformer model using Hugging Face Transformers:
In the above code, we are using Dataset, which uses the datasets library for seamless dataset handling, Tokenizer to convert text into token IDs with truncation and padding for uniform input size, and Output, which is a Ready-to-use PyTorch/TensorFlow format for transformer training.
Hence, this is a standard preprocessing pipeline for transformer models.
