:: Detect Python interpreter (prefer isolated .venv, fallback to system Python / bundled WinPython)

:: ============================================================
:: 1. First, try project .venv (isolated, highest priority)
:: ============================================================

:: ============================================================
:: 2. First, try system Python (preferred)
:: ============================================================

:: 1a. Check common system Python installation paths

:: 1b. Try PATH via `where python` - get the first one that's NOT in TRAE/IDE directories

:: ============================================================
:: 2. Fallback to bundled WinPython (legacy isolated mode)

:: 2e. Try sibling projects' WinPython (Seedvr2 / TTS_MultiModel / Image_MultiModel)——同级相对探测，可用 SEEDVR2_WPY / TTS_WPY / IMAGE_WPY 环境变量覆盖

:: ============================================================
:: 3. No Python found at all
:: ============================================================
echo [ERROR] Python interpreter not found!
echo.
echo ============================================================
echo   You have two options:
echo ============================================================
echo.
echo   Option A (Recommended) - Use system Python:
echo     1. Install Python 3.10+ from https://www.python.org/downloads/
echo        Make sure to check "Add Python to PATH" during installation.
echo     2. Verify: open Command Prompt and run: python --version
echo     3. Run pip install -r requirements.txt
echo     4. Then re-run start.bat
echo.
echo   Option B - Use bundled WinPython (isolated):
echo     1. Download WinPython from:
echo        https://github.com/winpython/winpython/releases
echo     2. Extract to project directory so this exists:
echo        %~dp0WPy64-312101\python\python.exe
echo     3. Then re-run start.bat
echo.
