hugohrban/progen2-small-mix7

This is the one-directional model trained on 7 protein families:

• PF00002 - GPCRs
• PF00042 - Globins
• PF00125 - Core histones
• PF00127 - Copper binding proteins
• PF00257 - Dehydrins
• PF00262 - Calreticulins
• PF03668 - P-loop ATPase

Check out the github repo for more information.

Example usage:

from transformers import AutoModelForCausalLM
from tokenizers import Tokenizer
# optionally use local imports
# from models.progen.modeling_progen import ProGenForCausalLM
# from models.progen.configuration_progen import ProGenConfig
import torch
import torch.nn.functional as F

# load model and tokenizer
model = AutoModelForCausalLM.from_pretrained("hugohrban/progen2-small-mix7", trust_remote_code=True)
tokenizer = Tokenizer.from_pretrained("hugohrban/progen2-small-mix7")
tokenizer.no_padding()

# prepare input
prompt = "<|pf03668|>1MEVVIVTGMSGAGK"
input_ids = torch.tensor(tokenizer.encode(prompt).ids).to(model.device)

# forward pass
logits = model(input_ids).logits

# print output probabilities
next_token_logits = logits[-1, :]
next_token_probs = F.softmax(next_token_logits, dim=-1)
for i in range(tokenizer.get_vocab_size(with_added_tokens=False)):
    print(f"{tokenizer.id_to_token(i)}: {100 * next_token_probs[i].item():.2f} %")
