怎么得到shape=(b, l, d)的image feature

model, image_processor = create_model_from_pretrained(model_name='ViT-SO400M-14-SigLIP-384', pretrained=self.image_tower_name, image_mean=([0.5,0.5,0.5]), image_std=([0.5,0.5,0.5]), image_interpolation="bicubic", image_resize_mode="squash") image_features = model.encode_image(images) # [1, 1152] 这样得到的feature是 （1， 1152），序列长度怎么得到，用model.forward_features(images) 报错timm ttributeError: 'CustomTextCLIP' object has no attribute 'forward_features'
