Same issue here with Anaconda in a jupyter notebook on sagemaker, langchain==0.0.158, python3.9, with this simple custom LLM example: https://python.langchain.com/en/latest/modules/models/llms/examples/custom_llm.html

[yinyijie]

Some kind of race condition bug?

Seems to be fixable by explicitly

import langchain
langchain.verbose = False

before trying to initialize llm.

[MoAmrYehia]

@wafflecomposite This solution worked for me. Thanks!

[iamulya]

This issue seems to have resurfaced in version 0.0.234 of langchain. The suggested solution in the issue works only temporarily, meaning the issue popped up after some time again.

this did not work for me.

[ryanholtschneider2]

Getting this error in 0.0.299 as well

[jorrgme]

Just in case someone gets this error now, the only thing that worked for me was updating langchain's version. In my case I'm using poetry as my package manager and did:

poetry update langchain

If you're using pip just use:

pip install --upgrade langchain

I tried using the langchain.verbose = False workaround that was mentioned here but it ended up triggering the same error later.

[fabilix]

This issue still appears in the latest version (0.0.332). Is there a known solution?

[wafflecomposite]

My langchain.verbose = False "solution" is no longer relevant since #11311

@fabilix check out a suggestions on this issue #9854
If that doesn't help, add a comment there too. Apparently it's still an unsolved problem.

I also faced this issue. In my case it was my folder structure messing with the imports. I had a folder called langchain within my project. After I renamed it it worked fine.

我也遇到过这个问题。就我而言，是我的文件夹结构弄乱了导入。我在我的项目中有一个文件夹。重命名后，它工作正常。langchain

good job bro, i have solved the question due to your reply

it works, I can't belive the reason is this stupid LOL.

[jy1989]

For me, I had a file named langchain.py make this error.

change the name it seems ok -__-

[cauchycai]

I named my python file "langchain.py". When I ran it using "python langchain.py", I get this error. After I renamed the "langchain.py" to some other name, the error is gone.
