Ollama
Let's load the Ollama Embeddings class.
from langchain_community.embeddings import OllamaEmbeddings
API Reference:
embeddings = OllamaEmbeddings()
text = "This is a test document."
To generate embeddings, you can either query an invidivual text, or you can query a list of texts.
query_result = embeddings.embed_query(text)
query_result[:5]

Let's load the Ollama Embeddings class with smaller model (e.g. llama:7b). Note: See other supported models https://ollama.ai/library
embeddings = OllamaEmbeddings(model="llama2:7b")
text = "This is a test document."
query_result = embeddings.embed_query(text)
