Having Issues with Langchain - 'TokenTextSplitter' from 'langchain.text_splitter'

Hi, did you install langchain?

pip install langchain

@admin Hi Hassan Thanks for the response .. I Have installed Lanchain but the issue still persists.

@vinsonkvictor please can you show me a screenshot of the error

@vinsonkvictor Hello friend, try updating the package:

pip install --upgrade langchain

Check if the TokenTextSplitter class exists within the langchain.text_splitter

import langchain.text_splitter

if hasattr(langchain.text_splitter, 'TokenTextSplitter'):
print("TokenTextSplitter class exists")
else:
print("TokenTextSplitter class does not exist")

@yasser-helbawi no the class is not found.

Here is the response from Bard (ChatGPT) wasn't as specific with solutions:

Here are the potential causes and solutions:

1. Incorrect Langchain Version:

Check your version: pip show langchain
Upgrade if necessary: pip install -U langchain
Specifically, avoid version 0.0.40: It had known issues with certain modules.
2. Python Version Incompatibility:

Langchain 0.0.208 and later require Python 3.10 or newer.
Check your version: python --version
Upgrade if needed: Install Python 3.10 from  https://www.python.org/downloads/ 
3. Missing or Corrupted Installation:

Reinstall Langchain: pip uninstall langchain && pip install langchain
4. Conflicting Module Names:

Check for other modules named text_splitter: pip list
Rename or remove them if necessary.
5. Caching Issues:

Clear pip cache: pip cache purge
Additional Steps:

Verify Installation Path: python -c "import langchain; print(langchain.__file__)"
Check for Typos: Ensure correct capitalization and spelling in the import statement.
Consult Documentation: Refer to the official Langchain documentation for troubleshooting:  https://langchain.readthedocs.io/ 
Seek Community Help: If none of these solutions work, reach out to the Langchain community on GitHub or Discord for further assistance.

Guess i am running an older version of Python and hence the lanchain is a previous version missing the class

@vinsonkvictor as @husein-aboul-hasan suggested, try updating the packages

@admin Upgraded Python.. It works now.. Thanks
