If I want to backup and restore the training data to another vanna instance, is there any guidence?
Where is the data location for chroma data?

Hello @njalan! :] This sounds more like a discussion topic than an issue.

Previously, I have created the chroma.sqlite3 file by training on relevant data and stored it in an Azure storage. Then for deployment of a container, I download the chroma.sqlite3 file into the container and point to it for the persistent storage when initializing the Chroma/Vanna instance. That way I always have backup and I avoid training during app launch.

@zainhoda

but which config I should pass?
I have choromadb in my local

class MyVanna(ChromaDB_VectorStore, OpenAI_Chat):
def init(self, config=None):
ChromaDB_VectorStore.init(self, config=config)
OpenAI_Chat.init(self, config=config)

vn = MyVanna(config={'api_key': '************************', 'model': 'gpt-4'})
