vit-gpt2-stablediffusion2-lora

Description

It is a ViT model that has been fine-tuned on a Stable Diffusion 2.0 image dataset and applied LORA.
It produces optimal results in a reasonable time. Moreover, its implementation with Pytorch is straightforward.

Usage

# Libraries
from transformers import ViTFeatureExtractor, AutoTokenizer, VisionEncoderDecoderModel

# Model
model_id = "nttdataspain/vit-gpt2-stablediffusion2-lora"
model = VisionEncoderDecoderModel.from_pretrained(model_id)
tokenizer = AutoTokenizer.from_pretrained(model_id)
feature_extractor = ViTFeatureExtractor.from_pretrained(model_id)

# Predict function
def predict_prompts(list_images, max_length=16):
    model.eval()
    pixel_values = feature_extractor(images=list_images, return_tensors="pt").pixel_values
    with torch.no_grad():
        output_ids = model.generate(pixel_values, max_length=max_length, num_beams=4, return_dict_in_generate=True).sequences

    preds = tokenizer.batch_decode(output_ids, skip_special_tokens=True)
    preds = [pred.strip() for pred in preds]
    return preds

# Get an image and predict
img = Image.open(image_path).convert('RGB')
pred_prompts = predict_prompts([img], max_length=16)
