确保在运行代码的同一个conda环境中安装了chromadb包。请按照以下步骤操作：

1. 激活你的conda环境：

   conda activate your_env_name

2. 安装chromadb包：

   pip install chromadb

3. 验证chromadb包是否正确安装：

   pip show chromadb

如果问题仍然存在，请确保你使用的是正确的导入机制。Chroma模块是通过自定义导入器动态导入的，这个导入器处理可选导入和弃用警告。以下是相关代码片段：

from typing import TYPE_CHECKING, Any

from langchain._api import create_importer

if TYPE_CHECKING:
    from langchain_community.vectorstores import Chroma

DEPRECATED_LOOKUP = {"Chroma": "langchain_community.vectorstores"}

_import_attribute = create_importer(__package__, deprecated_lookups=DEPRECATED_LOOKUP)

def __getattr__(name: str) -> Any:
    return _import_attribute(name)

__all__ = [
    "Chroma",
]

确保你的代码与此导入结构一致，以避免任何ImportError ^[1][2].

I had a similar problem, I eventually solved it by reinstalling chromadb== 0.5.5 and adjusting the versions of some dependencies.

[Renpf2022]

Go back to Python 3.10 and reinstall the environment. Because newer versions of Chromadb and its dependencies do not support Python>3.11. At the beginning, my Python version was 3.12, which resulted in the installation of only version 0.3.23 of Chromadb, causing a bug
