Node import failed: ModuleNotFoundError: No module named 'scripts.reactor_version'

[hegang9]

First, confirm

• I have read the instruction carefully
• I have searched the existing issues
• I have updated the extension to the latest version

What happened?

It worked normally before, but after a while the node cannot be imported. I have tried updating the warehouse and insightface has been installed successfully.

Steps to reproduce the problem

Your workflow

Sysinfo

python 3.12.7
pytorch version: 2.8.0+cu126

The problem has been solved. The problem lies in the init.py of the plug-in. I have installed other plug-ins, and there are scripts in other plug-ins. The original __init.py uses absolute paths to find scripts, which will cause file conflicts with the same name. Just change the path search in Iinit.py to a relative path. The modified init.py is as follows:
import sys
import os
import importlib

1. Get the current directory

current_dir = os.path.dirname(os.path.abspath(file))

2. Insert it at the beginning of the search path (to gain priority)

if current_dir not in sys.path:
sys.path.insert(0, current_dir)

3. Try importing it to see if you can find reactor_version.

try:
import scripts.reactor_version
except ImportError:

4. If an error occurs, it means there is already an incorrect "scripts" entry in memory, occupying the memory space without actually using it.

There's no other way now; we have to kick it out to let the ReActor survive.

if "scripts" in sys.modules:
    del sys.modules["scripts"]

Re-import after kicking

    import scripts.reactor_version

5. Restore normal loading process

from .nodes import NODE_CLASS_MAPPINGS, NODE_DISPLAY_NAME_MAPPINGS

all = ["NODE_CLASS_MAPPINGS", "NODE_DISPLAY_NAME_MAPPINGS"]

Thanks @hegang9 That is indeed the solution. Just wanted to give the complete file with hacky changes:

import importlib

current_dir = os.path.dirname(os.path.abspath(__file__))
if current_dir not in sys.path:
    sys.path.insert(0, current_dir)

try:
    import scripts.reactor_version
except ImportError:
    if "scripts" in sys.modules:
       del sys.modules["scripts"]
       import scripts.reactor_version

# repo_dir = os.path.dirname(os.path.realpath(__file__))
# sys.path.insert(0, repo_dir)
original_modules = sys.modules.copy()

# Place aside existing modules if using a1111 web ui
modules_used = [
    "modules",
    "modules.images",
    "modules.processing",
    "modules.scripts_postprocessing",
    "modules.scripts",
    "modules.shared",
]
original_webui_modules = {}
for module in modules_used:
    if module in sys.modules:
        original_webui_modules[module] = sys.modules.pop(module)

# Proceed with node setup
from .nodes import NODE_CLASS_MAPPINGS, NODE_DISPLAY_NAME_MAPPINGS

__all__ = ["NODE_CLASS_MAPPINGS", "NODE_DISPLAY_NAME_MAPPINGS"]

# Clean up imports
# Remove repo directory from path
sys.path.remove(current_dir)
# Remove any new modules
modules_to_remove = []
for module in sys.modules:
    if module not in original_modules and not module.startswith("google.protobuf") and not module.startswith("onnx") and not module.startswith("cv2"):
        modules_to_remove.append(module)
for module in modules_to_remove:
    del sys.modules[module]

# Restore original modules
sys.modules.update(original_webui_modules)
