设置¶

如果你在 colab 上打开此 Notebook，你可能需要安装 LlamaIndex 🦙。

In [ ]

%pip install llama-index-embeddings-together

%pip install llama-index-embeddings-together

# You can set the API key in the embeddings or env
# import os
# os.environ["TOEGETHER_API_KEY"] = "your-api-key"

from llama_index.embeddings.together import TogetherEmbedding

embed_model = TogetherEmbedding(
    model_name="togethercomputer/m2-bert-80M-8k-retrieval", api_key="..."
)

# 您可以在嵌入或环境变量中设置 API 密钥 # import os # os.environ["TOEGETHER_API_KEY"] = "your-api-key" from llama_index.embeddings.together import TogetherEmbedding embed_model = TogetherEmbedding( model_name="togethercomputer/m2-bert-80M-8k-retrieval", api_key="..." )

获取嵌入¶

In [ ]

embeddings = embed_model.get_text_embedding("hello world")

embeddings = embed_model.get_text_embedding("hello world")

In [ ]

print(len(embeddings))

print(len(embeddings))

768

In [ ]

print(embeddings[:5])

print(embeddings[:5])
