I understand that you're encountering an ImportError when trying to import the 'Protocol' class from the 'typing-extensions' package. This issue is likely due to a version mismatch of the 'typing-extensions' package. The 'Protocol' class is not available in the version you have installed (4.3.0).

To resolve this issue, you need to upgrade 'typing-extensions' to a version that includes the 'Protocol' class. You can do this by running the following command:

pip install --upgrade typing-extensions

After upgrading 'typing-extensions', you should be able to import the 'Protocol' class and your code should work as expected:

from typing_extensions import Protocol
from langchain.llms import OpenAI
llm = OpenAI(model_name='text-davinci-003', temperature=0.7, max_tokens=512)
print(llm)

This solution should resolve the ImportError you're experiencing. However, if you're using Azure OpenAI, you should use the AzureOpenAI class instead of OpenAI. Here's how you can do it:

from langchain.llms import AzureOpenAI
llm = AzureOpenAI(deployment_name="td2", model_name="text-davinci-002")

Please replace "td2" with your own deployment name.

This is one potential solution to your problem. If you find that this solution works and you believe it's a bug that could impact other users, we encourage you to make a pull request to help improve the LangChain framework. If this solution does not align with your experience or if you're still encountering issues, I recommend checking if you're using the latest version of LangChain, as the issue may have been resolved in a more recent update.

Hi, @srikanthgirijala! I'm Dosu, and I'm helping the LangChain team manage our backlog. I wanted to let you know that we are marking this issue as stale.

From what I understand, the issue you reported is an ImportError related to the 'Protocol' module from the 'typing' library. Specifically, it occurs when trying to import the 'OpenAI' module from the 'langchain.llms' package. I provided a potential solution, suggesting to upgrade the 'typing-extensions' package to a version that includes the 'Protocol' class. This solution was well received by users HashemAlsaket and devstein.

Before we close this issue, we wanted to check with you if it is still relevant to the latest version of the LangChain repository. If it is, please let us know by commenting on this issue. Otherwise, feel free to close the issue yourself, or it will be automatically closed in 7 days.

Thank you for your contribution to the LangChain repository!
