ValueError: text input must of type `str` (single example), `List[str]` (batch or single pretokenized example) or `List[List[str]]` (batch of pretokenized examples).
I am trying to run the evaluation of both MCLIP on zero-shot learning task found on this notebook [colab](https://colab.research.google.com/drive/1zfWeVWY79XXH63Ci-pk8xxx3Vu_RRgW-?usp=sharing).

the model is loaded using the below code

```
if MODEL_TYPE == 'mClip':
    from sentence_transformers import SentenceTransformer
    # Here we load the multilingual CLIP model. Note, this model can only encode text.
    # If you need embeddings for images, you must load the 'clip-ViT-B-32' model
    se_language_model = SentenceTransformer('clip-ViT-B-32-multilingual-v1')
    se_image_model = SentenceTransformer('clip-ViT-B-32')
    language_model = lambda queries: se_language_model.encode(queries, convert_to_tensor=True, show_progress_bar=False).cpu().detach().numpy()
    image_model = lambda images: se_image_model.encode(images, batch_size=1024, convert_to_tensor=True, show_progress_bar=False).cpu().detach().numpy()
```
when running the below prediction cell

```
top_ns = [1, 5, 10, 100]
acc_counters = [0. for _ in top_ns]
n = 0.

for i, (images, target) in enumerate(tqdm(loader)):
    images = images
    target = target.numpy()
    # predict
    image_features = image_model(images)
    image_features = image_features / np.linalg.norm(image_features, axis=-1, keepdims=True)
    logits = 100. * image_features @ zeroshot_weights

    # measure accuracy
    accs = accuracy(logits, target, topk=top_ns)
    for j in range(len(top_ns)):
        acc_counters[j] += accs[j]
    n += images.shape[0]

tops = {f'top{top_ns[i]}': acc_counters[i] / n * 100 for i in range(len(top_ns))}

print(tops)

```
I get the below error

```

How can this be fixed?
Looks like an issue with the sentence-transformers library, not Transformers. Cc-ing @ArthurZucker who may other ideas.<|||||>I don't really but gonna try to have a look through the notebook. <|||||>@alhuri could you provide a functioning notebook with the reproduction script? This one does not work for me (missing packages etc) with the config you are using? Thanks<|||||>This issue has been automatically marked as stale because it has not had recent activity. If you think this still needs to be addressed please comment on this thread.
