我在Python 3.7 venv上安装了tensorflow-gpu 1.15.2。我没有安装tensorflow程序包。
我安装了CUDA 9.0(因为我使用的是tensorflow 1.15(和CUDA 9.0的相应cuDNN。当我运行tensorflow学习算法时，它使用我的CPU而不是GPU。我跑了：
from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())
它检测到我的GPU(1660 Ti(，但它说我缺少很多包：

我在电脑上搜索了一下，确实找不到那些dll文件。
当我安装CUDA时，如果我试图重新安装，它会说"图形驱动程序找不到兼容的图形硬件。"我忽略了错误，还是安装了。我的程序文件中的相关CUDA目录就在那里。但是cmd提示符中的nvcc -V确认CUDA已安装。
快速搜索似乎表明CUDA 10+版本有这些库，但安装后我没有看到任何区别。
我在哪里可以找到这些丢失的dll？我有没有安装错误？
哦，似乎100指的是CUDA 10.0，所以CUDA 9.0有***90.dll文件，CUDA 10.2有***102.dll文件。
需要这么多不同的CUDA安装真的很烦人！
