NOTE: THIS IS THE RANDOM SAMPLING VERSION WEPO. DOM TREE DISTANCE-BASED VERSION WILL BE RELEASED SOON.
Below is the reference code for inference. First load the tokenizer and the model.
from transformers import AutoTokenizer, AutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained("KLGR123/WEPO-gemma-2b", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("KLGR123/WEPO-gemma-2b", trust_remote_code=True).to('cuda:0')
Run a test-demo with random input.
