为什么tensorflow dll没有运行？

Question

最重要的是，我不编码。 但出于好奇，我开始检查unity。我正在尝试一个关于使用python和tensorflow在卡丁车游戏中学习AI的教程，我在视频中做了一切来安装它们（他们说这是我运行这个教程所需要的全部）。 所以在建立了我的虚拟环境之后，我运行了这个

C:\Users\L\MyFirstGame>mlagents-learn Assets\Karting\Prefabs\AI\kart_mg_trainer_config.yaml --train --run-id=custom-track-1

我得到了这个

我确实检查了tensorflow页面，找到了错误的解决方案，但没有帮助，所以我来了

我猜你想使用tensorflow gpu，但错误显示tf无法加载cudnn的dll。（我猜），可能你没有安装cudnn，或者你的tensorflow gpu版本不适合你的gpu和cudnn
