由于最开始以为GTX960M显卡仅仅能支持cuda9.0，但是在2021年1月26日，英伟达非常良心地更新驱动，让GTX960M也支持cuda11了（感谢英伟达！）

一、更新驱动
根据：https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html#cuda-general-new-features
1.1 下载GTX960M对应的安装程序
https://www.nvidia.cn/geforce/drivers/
1.2 安装
1.3 更新驱动
1.4 查看对应cuda版本
二、查看tensorflow、python、cuda、cudnn版本对应关系：
https://tensorflow.google.cn/install/source_windows
三、 下载库：
3.1 在anconda中创建conda环境
启动powershell
3.2 更改源，加快下载速度
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 --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/linux-64/
conda config --set show_channel_urls yes
3.3 安装：
python -m pip install --upgrade pip
pip install keras -i https://pypi.douban.com/simple
conda install cudatoolkit=11.0
conda install cudnn=8.0
pip install tensorflow-gpu==2.4 -i https://pypi.douban.com/simple
#conda install tensorflow-gpu
pip3 install pillow -i https://pypi.douban.com/simple/
继续安装：
pip install -U keras-tuner -i https://pypi.douban.com/simple/
conda install matplotlib
pip install opencv-python -i https://pypi.douban.com/simple/
安装jupyter notebook补齐插件
python -m pip install jupyter_contrib_nbextensions -i https://pypi.douban.com/simple
jupyter contrib nbextension install --user --skip-running-check
安装完成后，勾选 “Table of Contents” 以及 “Hinterland”

实际测试:
有些奇怪 GPU占用率变低了，更多调用的是CPU
后面发现其实后台显卡是占用了97%了，任务管理器还是认为是只占了30%
