Protein Amino-Acid Fast Tokenizer
Fast Rust-backed tokenizer for protein sequences.
Features
- 1 token = 1 amino acid — character-level tokenization
- Fast Rust backend — efficient processing via HuggingFace Tokenizers
- Transformer-ready — compatible with
AutoTokenizer
Usage
from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("pszmk/protein-aa-fast-tokenizer")
# Single sequence
tokens = tokenizer("MKTLLILAVAVCSAA")
print(tokens)
# {'input_ids': [2, 16, 14, ...], 'attention_mask': [1, 1, ...]}
# Batch with padding
batch = tokenizer(
["MKTLLILAVAVCSAA", "ACDEFGHIK"],
padding=True,
return_tensors="pt",
)
