AttributeError: module 'NodeRAG' has no attribute 'NodeConfig'
This error indicates that your code is trying to dynamically import a class called `NodeConfig` from the `NodeRAG` module, but that class does **not exist** (or is not visible) in the module.
---
### ✅ What the Error Means
From the traceback:
```python
self._class = getattr(self._module, self.class_name)
AttributeError: module 'NodeRAG' has no attribute 'NodeConfig'
```
This means:
- Somewhere (likely in `config.py` or `app.py`), you’re calling:
```python
NG = lazy_import("NodeRAG", "NodeConfig")
```
- Then this lazy importer tries:
```python
import NodeRAG
getattr(NodeRAG, "NodeConfig") # fails here
```
- But `NodeRAG/__init__.py` does **not expose NodeConfig**, or the class **is named something else / in a different file**.
---
### 🎯 How to Fix It
#### **Option 1 – Export `NodeConfig` in `NodeRAG/__init__.py`**
If `NodeConfig` exists but isn’t exported:
**Open:** `NodeRAG/__init__.py`
**Add:**
```python
from .config import NodeConfig # or wherever NodeConfig actually is
__all__ = ["NodeConfig"]
```
---
#### **Option 2 – Class isn’t Named `NodeConfig`, Wrong Name**
Search for what the class is actually called:
```bash
grep -R "class NodeConfig" -n NodeRAG
```
If the class is named something like `NGConfig`, update the call:
```python
state_controller = NG(NGConfig(all_config()), web_ui=True)
```
Or change the lazy import:
```python
NG = lazy_import("NodeRAG", "NGConfig")
```
---
#### **Option 3 – Module Path Wrong**
If `NodeConfig` is inside a deeper module like `NodeRAG/config/node_config.py`, update the lazy import to:
```python
NG = lazy_import("NodeRAG.config.node_config", "NodeConfig")
```
---
### 📍 Where to Start Debugging
Check in `NodeRAG/utils/lazy_import.py` where it’s used:
```python
state_controller = NG(NGConfig(all_config()), web_ui=True)
```
Check how `NG` is defined above. It'll look like:
```python
NG = LazyImport("NodeRAG", "NodeConfig")
```
Now confirm:
✅ Does `NodeRAG/NodeConfig.py` exist?
✅ Does the class exist and is named correctly?
✅ Is it imported into `NodeRAG/__init__.py`?
---
### ✅ Want me to generate the exact fix in code after you show me the file structure or relevant snippet?
I can write the correction to your `lazy_import`, module structure, or class definition.
Just say **“show fix”** or send me your `NodeRAG/` folder structure.
