如果您在 Colab 上打开这个笔记本，您可能需要安装 LlamaIndex 🦙。

%pip install llama-index-embeddings-google

!pip install llama-index

# imports
from llama_index.embeddings.google import GooglePaLMEmbedding

# get API key and create embeddings

model_name = "models/embedding-gecko-001"
api_key = "YOUR API KEY"

embed_model = GooglePaLMEmbedding(model_name=model_name, api_key=api_key)

embeddings = embed_model.get_text_embedding("Google PaLM Embeddings.")
