我最近在写一个python应用的时候遇到了一个报错：

2025-05-12 11:36:59 - ERROR - [__main__:minimal_pyqt_llama_test.py:32] - Llama model load FAILED: exception: access violation reading 0x0000000000000000
Traceback (most recent call last):
File "D:\PythonProjects\GameAssistant\minimal_pyqt_llama_test.py", line 28, in attempt_load_llama
llm = Llama(model_path=model_path, n_ctx=n_ctx, verbose=verbose, n_gpu_layers=n_gpu_layers)
File "D:\PythonProjects\GameAssistant\game_assistant_env\lib\site-packages\llama_cpp\llama.py", line 204, in __init__
llama_cpp.llama_backend_init()
OSError: exception: access violation reading 0x0000000000000000

一开始，我认为是我的文件地址写错了，于是我反复对比D:/models/Phi-3-mini-4k-instruct-q4.gguf却发现确实没有问题，那就很费解了，为什么会出现这种情况，于是我反复测试反复测试，在经过长达2天的测试后，我决定先看看底层之间是否有冲突，于是我编写了两个测试文件分别是：

# test_llm_load.py

from llama_cpp import Llama

import logging

logging.basicConfig(level=logging.DEBUG)

logger = logging.getLogger(__name__)

model_path = "D:/models/Phi-3-mini-4k-instruct-q4.gguf"

try:

logger.info(f"Attempting to load model from: {model_path}")

llm = Llama(

model_path=model_path,

n_ctx=512,

n_gpu_layers=0,

verbose=True

)

logger.info("Model loaded successfully!")

except Exception as e:

logger.error(f"Error loading or using Llama model: {e}", exc_info=True)

and

# minimal_pyqt_llama_test.py

import sys

import logging

from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QPushButton, QTextEdit

# --- 日志配置 ---

logging.basicConfig(

level=logging.DEBUG,

format='%(asctime)s - %(levelname)s - [%(n
