运行Django应用时触发Numpy的'Unqualified exec'语法错误求助

Hey there, let's work through this issue you're facing with your Django app. I'll break down the two problems here and walk you through fixes step by step!

1. Critical Issue: Numpy's "Unqualified exec" SyntaxError #

This is the main reason your app is crashing. Let's look at the clues in the traceback:

• You're targeting Python 3.6 (from the path /python3.6_rhel7/), but the error references Python 2.7's importlib module (/usr/lib64/python2.7/importlib/__init__.py). This points to either a Python environment conflict, or an incompatible Numpy version for your Python 3.6 setup.

Fixes: #

• Verify your Python environment first
  Run these commands to confirm you're using the correct interpreter (from your project's virtual environment):

  which python
  python --version
  

  Ensure the output points to your Python 3.6 virtual environment, not the system's Python 2.7. If it doesn't, reactivate your virtual environment properly.

• Install a Python 3.6-compatible Numpy version
  Python 3.6 is no longer supported by newer Numpy releases (Numpy 1.20+ dropped support for Python 3.6). Uninstall your current Numpy and install the latest compatible version:

  pip uninstall numpy
  pip install numpy==1.19.5
  

• Check for conflicting dependencies
  Run pip list to review all installed packages. Make sure none of them are pulling in Python 2.x-compatible versions that could cause import conflicts.

2. Warning: Model Already Registered #

The warning about dataServices.hsfiledetails being registered twice is less urgent but can lead to inconsistencies later. Here's how to fix it:

• Avoid wildcard imports in models/__init__.py
  Instead of using from .bugPred import * (which imports every model in bugPred.py), explicitly import only the models you need:

  # dataServices/models/__init__.py
  from .bugPred import YourActualModelName  # Replace with your model class name
  

• Check for circular imports
  Make sure bugPred.py isn't importing hsfiledetails (either directly or indirectly) while hsfiledetails.py also imports from bugPred.py. Circular imports can trigger duplicate model registration.
• Simplify model imports
  Keep your model file imports clean—avoid unnecessary cross-imports between model modules. Django automatically discovers models in your app's models directory, so you don't need to over-import them.

Final Steps #

1. Resolve the Numpy syntax error first (since it's stopping your app from running)
2. Then address the model registration warning to avoid future issues
3. Test your app again with python manage.py runserver 0.0.0.0:8002
