这个错误通常是由于Python版本不兼容导致的。 SentenceTransformer 需要 Python 3.6 或更高版本。请确保你的 Python 版本符合要求。你可以尝试升级你的 Python 版本,或者使用一个兼容的版本的 SentenceTransformer。你可以通过以下命令安装一个指定版本的 SentenceTransformer:
```python
pip install sentence-transformers==0.3.9
```
这将安装版本号为 0.3.9 的 SentenceTransformer,它与 Python 3.6 兼容。

根据您提供的错误信息,看起来是加载模型时出现了一些问题。具体来说,这个错误是由于加载了一个具有自定义代码的模型,并且在加载时没有明确指定修订版本。为了确保没有恶意代码被贡献到较新的修订版本中,建议显式地传递一个`revision`参数。
您可以尝试以下解决方法:
在`web_demo.py`文件中,将以下代码行:
```python
tokenizer = AutoTokenizer.from_pretrained("/home/nano/THUDM/chatglm-6b", trust_remote_code=True)
```
替换为:
```python
tokenizer = AutoTokenizer.from_pretrained("/home/nano/THUDM/chatglm-6b", trust_remote_code=True, revision="main")
```
这样会明确指定修订版本为"main",以避免加载模型时出现安全问题。请确保您已经下载了正确的模型文件并将路径指向正确的位置。
如果问题仍然存在,请提供更多详细信息,以便我能够更好地帮助您解决问题。

这段代码是一个Python脚本,主要用于加载MovieLens数据集中的电影和评分数据,并将其转换为图形数据,以便进行图形嵌入。其中,使用了以下库:
- os.path:用于处理文件路径的库。
- pandas:用于处理数据的库。
- torch:用于深度学习的库。
- sentence_transformers:用于生成句子嵌入的库。
- torch_geometric:用于处理图形数据的库。
首先,定义了一个URL和根目录,用于下载和存储MovieLens数据集。然后,定义了两个函数load_node_csv和load_edge_csv,用于加载节点和边的CSV文件,并将它们转换为PyTorch张量。最后,定义了一个名为SequenceEncoder的类,用于将序列数据转换为嵌入向量。
