车辆检测项目中无法从utils库导入load_weights函数问题咨询

Let's break down why this error pops up and walk through how to fix it:

• The core issue: You installed a third-party utils package via pip, but the utils your code is trying to import is almost certainly a custom local module that comes with your vehicle detection project (not the pip-installed one). The pip version of utils doesn't include a load_weights function, which is exactly why you're hitting this error.

Here are actionable fixes to try:

1. Confirm your project structure
   Check if there's a utils.py file or a utils folder (with an __init__.py file inside) in your project's root directory. This is the module your script expects to pull functions from. If it's missing, you might have accidentally deleted it or didn't download/clone the full project files.

2. Resolve the import path conflict
   If both the local utils module and the pip-installed utils package exist, Python might be prioritizing the pip one. Try these options:

   • Uninstall the pip-installed utils (if you don't need it for other projects):

     pip uninstall utils
     

   • Or, manually add your project's root directory to Python's search path at the top of your script:

     import sys
     sys.path.insert(0, "/path/to/your/project/root")
     from utils import load_weights, Box, yolo_net_out_to_car_boxes, draw_box
     

     Replace /path/to/your/project/root with the actual folder path where your local utils.py is stored.

3. Check the local utils module content
   Open your project's utils.py file and verify that a function named load_weights is actually defined inside it. Typos (like load_weight instead of load_weights) or missing function definitions are common culprits here.

4. Verify your working directory
   If you're running your script from a subfolder instead of the project root, Python might fail to locate the local utils module. Make sure you're executing the script from the same directory where utils.py lives.
