# FakeEmbeddings 集成

> 使用 LangChain Python 集成 FakeEmbeddings 嵌入模型。

LangChain 还提供了一个假的嵌入类。您可以使用它来测试您的流水线。

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
from langchain_community.embeddings import FakeEmbeddings
```

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
embeddings = FakeEmbeddings(size=1352)
```

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
query_result = embeddings.embed_query("foo")
```

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
doc_results = embeddings.embed_documents(["foo"])
```
