问题原因：
使用TensorFlow一个小模型是进行推理的时候，报了PTX错误：

查找错误原因是：
驱动和 CUDA/cuDNN 版本不兼容。

当前系统里只有cuda驱动没有安装CUDA、CuDNN。


因为牵涉到要尽量兼容其他机器的CUDA版本，就安装了当前这台机器支持的最高版本12.2。

安装CUDA12.2：

找到对应版本
CUDA Toolkit Archive | NVIDIA Developer

选择对应操作系统
CUDA Toolkit 12.2 Downloads | NVIDIA Developer


安装过程：
这里输入accept：


因为已经安装过 Nvidia 显卡驱动了，因此不需要再安装了。如果你尚未安装驱动，可以顺便一起安装了。摁一下空格取消 Driver 安装，直接选择 Install 安装：


安装成功：




安装Cuda12编译所需的CuDNN版本9.3.0：

pip install nvidia-cudnn-cu12==9.3.0.75

问题成功解决！
