LangChain 0.3.19中chromadb模块缺失及安装失败的问题求助
我最近在尝试用HuggingFaceBgeEmbeddings生成嵌入,再把这些嵌入加载到Chroma向量数据库中,用到的代码如下:
生成嵌入的代码:
embeddings = HuggingFaceBgeEmbeddings( model_name=model_name, model_kwargs=model_kwargs, encode_kwargs=encode_kwargs)
加载到Chroma的代码:
if not os.path.exists(db_directory): print(f"\n -- Creating a vector store {store_name} --") db = Chroma.from_documents( docs, embeddings, persist_directory=db_directory )
结果运行代码时直接报错,错误信息是:
import chromadb ModuleNotFoundError: No module named 'chromadb'
我查了相关解决方案,试着执行升级安装命令:
pip install --upgrade chromadb
没想到又遇到了新的编译错误,具体信息如下:
Building wheel for chroma-hnswlib (pyproject.toml) ... error error: subprocess-exited-with-error × Building wheel for chroma-hnswlib (pyproject.toml) did not run successfully. │ exit code: 1 ╰─> [5 lines of output] running bdist_wheel running build running build_ext building 'hnswlib' extension error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/ [end of output] note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building wheel for chroma-hnswlib Failed to build chroma-hnswlib
根据提示,我已经下载并安装了MSVC v143 - VS 2022 C++ x64/x86 build tools (v14.43-17.13),还先后安装了Windows 11 SDK (10.0.22621.0)和Windows 11 SDK (10.0.26100.0),但问题依然存在,LangChain还是找不到chromadb模块。
我的环境是:Windows 11 Home 10.0.26100 Build 26100,LangChain 0.3.19,Python 3.13.2。实在不知道该怎么解决了,恳请社区的各位大佬给点建议!
