计算机的GPU是2080TI。

按照这个网上的步骤安装的tensorflow2.0 http://www.manongjc.com/detail/15-kcqyretfrurcqmz.html。

具体来说，在安装anaconda后，运行了以下命令

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --set show_channel_urls yes

conda create -n tf2.0 python=3.7

activate tf2.0
conda install tensorflow-gpu==2.0

安装后，进入python测试了下，没发现问题。我在其他网站上看要安装visual studio, cuCNN, CUDA等。我这些都没安装，有问题吗？


运行以下命令
from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())

会打印出
