Latest: v0.2.5

What's new in v0.2.5

• Vocab size: 100000 tokens
• Trained on a larger and more diverse Amharic corpus
• Improved tokenization quality and detokenization accuracy
• Better handling of edge cases and rare words

1. Pretrained tokenizer loading

• You can now load a pretrained tokenizer directly:

from amharic_tokenizer import AmharicTokenizer
tok = AmharicTokenizer.load("amh_bpe_v0.2.5")

This version includes a pretrained model (amh_bpe_v0.2.5) that can be used immediately without any additional setup and training.

2. Full token-to-ID and ID-to-token functionality

• Added complete round-trip processing methods:

tokens = tok.tokenize(text)
ids = tok.encode(tokens)
detokenized = tok.detokenize(tokens)

The tokenizer now supports seamless conversion between tokens and IDs, ensuring full consistency between tokenization and detokenization.
