我已经在网上搜索了几个小时，但没有结果，所以决定在这里问一下。
我正在尝试制作一个自动驾驶汽车，参考了Sentdex的教程，但是在运行模型时，出现了一堆致命错误。我在互联网上搜索了很多解决方案，许多人似乎都有同样的问题。然而，我找到的所有解决方案（包括此Stack-post）都不适用于我。
这是我的软件：
- Tensorflow：1.5，GPU版本
- CUDA：9.0，带补丁
- CUDnn：7
- Windows 10 Pro
- Python 3.6
硬件：
- Nvidia 1070ti，具有最新驱动程序
- Intel i5 7600K
这是崩溃日志：

我发现导致Python崩溃并产生前三个错误的代码行是：
prediction = model.predict([screen.reshape(WIDTH,HEIGHT,1)])[0]。运行代码时，CPU占用率高达100％，表明出现了严重问题。GPU占用率约为40-50％。我尝试了Tensorflow 1.2和1.3，以及CUDA 8，但毫无成效。安装CUDA时，我没有安装特定的驱动程序，因为它们对我的GPU来说太旧了。尝试了不同的CUDnn，但也没有任何帮助。
