Compute image embeddings and positional image embeddings, given the pixel values of an image.
@param {Object} model_inputs Object containing the model inputs.
@param {Tensor} model_inputs.pixel_values Pixel values obtained using a `SamProcessor`.
@returns {Promise<{ image_embeddings: Tensor, image_positional_embeddings: Tensor }>} The image embeddings and positional image embeddings.
