Embedchain upgrade to latest version error

[Rainismer]

🐛 Describe the bug

Using embedchain version 0.1.124 everything works fine, but when upgrading to 0.1.125, chroma errors occur.

TypeError: SegmentAPI.get_or_create_collection() got an unexpected keyword argument 'embedding_function'

The key problem is the version upgrade from 0.1.124 to 0.1.125 causing a TypeError with SegmentAPI's get_or_create_collection() method, specifically related to the embedding_function argument.

Here's a step-by-step resolution:

1. Update ChromaDB Dependency
   First, ensure you're using a compatible version of ChromaDB. Update to at least version 0.4.13:

pip install chromadb>=0.4.13

2. Modify Collection Initialization
   Update your code to explicitly handle collection creation:

from embedchain import App

# Option 1: Specify collection name explicitly
app = App(config={
    "collection_name": "my_custom_collection"
})

# Option 2: If using a specific embedding function
from embedchain.embedder.openai import OpenAIEmbedder

embedder = OpenAIEmbedder()
app = App(embedder=embedder)

3. Potential Configuration Workaround
   If the above doesn't work, create a configuration file (config.yaml):

vectordb:
  provider: chroma
  config:
    collection_name: 'my-app-collection'

4. Clean Slate Approach
   If persistent issues occur:

• Delete existing Chroma DB folder
• Ensure embedding dimensions match your vector store configuration
• Reinstall Embedchain and ChromaDB

Recommendations:

• Verify you're using the latest compatible versions
• Check embedding dimension compatibility
• Ensure proper collection initialization

Would you like me to elaborate on any of these steps or do you need more specific guidance based on your exact implementation?

@AbhigyaWangoo Thank you for your reply, but it doesn't work for me.
