这个错误是由于网络连接问题导致无法下载所需的模型和文件。在初始化Chat时，脚本尝试从Hugging Face模型库中下载`Q-Former`模型，但由于无法连接到`https://huggingface.co`，导致下载失败。

请确保你的网络连接正常，并且能够访问`https://huggingface.co`网站。如果你使用的是代理，请确保代理设置正确。

如果你的网络连接正常，但仍然无法下载模型，你可以尝试使用离线模式运行脚本。在离线模式下，你需要手动下载所需的模型和文件，并将它们放置在正确的路径中。你可以参考Hugging Face文档中的离线模式部分了解更多信息。

希望这些提示能帮助你解决问题。如果你有其他疑问，请随时提问。

If you were trying to load it from 'https://huggingface.co/models', make sure you don't have a local directory with the same name. Otherwise, make sure 'bert-base-uncased' is the correct path to a directory containing all relevant files for a BertTokenizer tokenizer.

这个错误是由于无法加载'BertTokenizer'引起的。根据错误信息，它无法从本地或Hugging Face模型库中找到名为'bert-base-uncased'的tokenizer。

请确保你已经安装了相应的依赖项，并且可以从Hugging Face模型库中下载预训练的tokenizer。你可以使用以下命令安装必要的依赖项：

pip install transformers

如果你已经安装了`transformers`库但仍然遇到问题，可能是因为网络连接问题导致无法下载预训练模型。你可以尝试使用代理或手动下载所需的预训练模型。

另外，确保`bert-base-uncased`是正确的模型名称。你可以查看Hugging Face模型库以获取可用的模型名称和路径。
