when i try testing the model by uploading an image i get this error:  
HfApiJson(Deserialize(Error(“unknown variant `image-feature-extraction`, expected one of `audio-classification`, `audio-to-audio`, `audio-source-separation`, `automatic-speech-recognition`, `feature-extraction`, `text-classification`, `token-classification`, `question-answering`, `translation`, `summarization`, `text-generation`, `text2text-generation`, `fill-mask`, `zero-shot-classification`, `zero-shot-image-classification`, `conversational`, `table-question-answering`, `image-classification`, `image-segmentation`, `image-to-text`, `text-to-speech`, `text-to-audio`, `sentence-similarity`, `speech-segmentation`, `tabular-classification`, `tabular-regression`, `text-to-image`, `object-detection`, `visual-question-answering`, `video-classification`, `document-question-answering`, `image-to-image`, `depth-estimation`, `image-text-to-text`”, line: 1, column: 318)))

However, when i use the model using **pipeline** it works fine. what causes this problem and how can i solve it?
