Hello,

I tried to fine tune clip model in bi_encoder model and cross_encoder modes.
I prepared the training data (image, text) pair as shown below:
train_samples = [
InputExample(texts=[Image.open('175105641.jpeg'), 'grey basket'], label=0.3),
InputExample(texts=[Image.open('175105641.jpeg'), 'vegetable washer'], label=0.2)
]. Q1. Not sure whether this is correct.

and when I trained in bi_encoder mode, there is no error. But when I pass the evaluator, there is no evaluation results coming out. Q2. Wonder why there is no evaluation results showing.

Q3: Then I trained a cross_encoder, there is an error. I posted the code and error as below. It seems that cross_encoder mode for clip model is not ready in sentence_transformer.

code:
model_type = 'openai/clip-vit-base-patch32'
savepath_location = "clip-ViT-B-32_cross_encoder"
model_cross = CrossEncoder(model_type, num_labels=1)

train_dataloader = DataLoader(train_examples, shuffle=True, batch_size=32)
train_loss = losses.CosineSimilarityLoss(model_cross)
#, checkpoint_path=checkpoint_path_location remove checkpoint if it causes issue for now
model_cross.fit(train_dataloader=train_dataloader,
epochs=3,
warmup_steps=100,
evaluation_steps=-1,
output_path=savepath_location)
model_cross.save(savepath_location)

error:
ValueError: Unrecognized configuration class <class 'transformers.models.clip.configuration_clip.CLIPConfig'> for this kind of AutoModel: AutoModelForSequenceClassification.

Thanks for your reply. Best,
