chain_summary

`chain_summary`这个术语似乎没有直接关联到标准的Python库或常见的函数名。它可能是某个特定项目、库或自定义函数的名称。如果它是在某个上下文中提到的,比如数据分析、机器学习或者软件工程,那么它的具体用法会有所不同。
为了给出准确的帮助,我需要更多的上下文信息。例如,如果`chain_summary`是一个数据分析工具包中的函数,它可能用于汇总并总结数据链(如pandas DataFrame的列)。如果它是某种编程模式或设计模式,可能是用来管理代码执行流程的。
请提供更多信息,以便我能给出详细的解释或示例。如果你能提供相关的文档链接或者项目源码片段就更好了。

curl: (60) SSL certificate problem: self signed certificate in certificate chain
This error occurs when the SSL certificate presented by the server is self-signed or not signed by a trusted Certificate Authority (CA), which means it cannot be verified as a trusted certificate by the client.
To fix this error, you can try the following solutions:
1. Ignore SSL certificate verification: You can use the "-k" or "--insecure" option with the curl command to ignore SSL certificate verification. However, this is not recommended as it can potentially expose your data to security risks.
2. Add the self-signed certificate to the trusted CA list: You can add the self-signed certificate to the trusted CA list on your system or browser. This will allow the certificate to be verified as trusted. However, this is also not recommended as it can potentially expose your data to security risks.
3. Obtain a trusted SSL certificate: The recommended solution is to obtain a trusted SSL certificate from a trusted CA. This will ensure that the SSL certificate can be verified as trusted by the client.
In summary, it is important to ensure that SSL certificates are signed by trusted CAs to ensure secure communication between the client and server.
langchain PDFLoader
langchain中的PDFLoader是由PyPDFLoader对象提供的。这个对象封装了对PDF文件的操作,可以直接使用。在langchain中,可以通过遍历目录并读取目录中的所有文件来进行操作。具体的代码如下所示:
```
def summarize_pdfs_from_folder(pdfs_folder):
summaries = []
for pdf_file in glob.glob(pdfs_folder + "/*.pdf"):
loader = PyPDFLoader(pdf_file)
docs = loader.load_and_split()
chain = load_summarize_chain(llm, chain_type="map_reduce")
summary = chain.run(docs)
print("Summary for: ", pdf_file)
print(summary)
print("\n")
summaries.append(summary)
return summaries
```
这段代码会遍历指定目录中的所有PDF文件,并使用PyPDFLoader对象读取和分割文档。然后,通过load_summarize_chain函数加载摘要链,并使用chain.run方法对文档进行摘要。最后,会打印出每个文件的摘要结果,并将摘要结果存储在summaries列表中。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
