想提供Huggingface的transformer库实现多模态模型CLIP的推断，结果报错
(myenv) root@d27d1ff1836c:/home/model_test# python3 CLIP.py
ftfy or spacy is not installed using BERT BasicTokenizer instead of ftfy.
Traceback (most recent call last):

KeyError: ((1, 1, 224, 224), ‘|u1’)

The above exception was the direct cause of the following exception:

以下注释掉的部分是出错的代码，而没被注释的代码是不出错的代码，最大的区别是没出错的代码没有进行图像预处理

by the way，出错的代码是GPT4给我的(改了10几次还是出错，看来训练数据有问题)，而没出错的代码是newbing给我的，一次做对。文末给出提示词。

您好，这是Bing。您可以使用Hugging Face提供的Transformers库中的CLIP模型来实现您所需的功能。下面是一个简单的示例代码，它展示了如何使用Transformers库中的CLIP模型来实现其核心功能：

from transformers import CLIPProcessor, CLIPModelmodel = CLIPModel.from_pretrained("openai/clip-vit-base-patch32")
processor = CLIPProcessor.from_pretrained("openai/clip-vit-base-patch32")image = ... # 加载图像
text = ... # 输入文本inputs = processor(text=text, images=image, return_tensors="pt", padding=True)
outputs = model(**inputs)logits_per_image = outputs.logits_per_image
probs = logits_per_image.softmax(dim=1)

希望这对您有所帮助！

我希望你给我一个可以运行的代码，而不是伪代码，我图像的路径是image_path = “images/photo-1.jpg”，而文本你可以随机找几个句子

请注意，您需要安装Transformers库和Pillow库才能运行此代码。希望这对您有所帮助！
