Chromadb
This is the default database used when no vectordb is specified . We create a temp directory and persist the embeddings there using the PersistentClient of Chromadb by default.
This is for experimentation purposes when the user wants a quick headstart and wants to experiment with things quickly.
Compulsory arguments:
class_name => The name of the index under which documents are stored
Here are some sample configurations:
=> Chromadb with embedding specification
"vectordb": {
"name": "chromadb",
"class_name": "genai_stack",
"embedding": {
"name": "HuggingFaceEmbeddings",
"fields": {
"model_name": "sentence-transformers/all-mpnet-base-v2",
"model_kwargs": { "device": "cpu" }
}
}
}
==> Chromadb without embedding specification. Without any embedding specification we use the default embedding which is HuggingFaceEmbeddings
"vectordb": {
"name": "chromadb",
"class_name": "genai_stack"
}
Python Usage:
from genai_stack.vectordb.chromadb import ChromaDB
config = {"class_name": "MyIndexName"}
vectordb = ChromaDB.from_kwargs(config)
vectordb.search("Your question")
# Output
# <Documents closest to your question>
