To address the rate limit error with DuckDuckGo, consider implementing retry logic with exponential backoff, using caching to store and reuse results, or contacting DuckDuckGo for a higher rate limit or an API key.

For the import error, it seems there's been a change in the LangChain library. The correct import now is likely from a different module or with a different name, such as DuckDuckGoSearchAPIWrapper from langchain_community.utilities. Ensure you're using the latest version of LangChain and update your import statements accordingly. Check the LangChain documentation or release notes for any changes related to DuckDuckGoSearch.

@dosu thank you that is helpful even its not the precise solution and also i think am using the latest imports i mean when using from langchain_community.tools import DuckDuckGoSearchRun it means that is it calling `` try:
--->from duckduckgo_search import DDGS
except ImportError:
also "DuckDuckGoSearchAPIWrapper" is used to have more control over the search result Eg:-DuckDuckGoSearchAPIWrapper(region="de-de", time="d", max_results=2)```

It seems like you're encountering two distinct issues: a rate limit error from DuckDuckGo and an import error related to the LangChain library.

For the rate limit error, it's important to implement robust error handling in your application. This includes using the Retry-After header DuckDuckGo provides in their rate limit responses to adjust the timing of your requests accordingly. This approach will help you manage the rate limit more effectively, even if DuckDuckGo has recently tightened their restrictions.

Regarding the import error, it appears there might be some confusion or changes in the LangChain library that are affecting your code. Since you're already using what you believe to be the latest import paths, I recommend closely reviewing the most recent LangChain documentation or release notes for any updates or changes in the library structure. Libraries and their structures can evolve, leading to such issues if the changes are not reflected in user code promptly.

Additionally, engaging with the LangChain community could provide further insights or workarounds. Other users might have encountered similar issues and could offer solutions or advice on how to adjust your code to work with the latest version of LangChain.

Remember, staying up-to-date with library documentation and actively participating in community discussions are key strategies for quickly resolving these types of issues.

This has been happening to my team over the past week or so. I only make a few requests a day, so likely some sort of bug or change in underlying libaries langchain has not caught up to yet.

[dave-16]

yes you are right it is some unhandled part in the updated versions. your team might test using pip install -U duckduckgo_search==5.3.1b1

[dave-16]

this version works guys
pip install -U duckduckgo_search==5.3.1b1
