Win10安装tensorflow-gpu以及对应版本的keras

怎么说捏，搞了一天好不容易安装成功，后来又需要安装其他的东西（matplotlib）把环境搞崩溃了，于是只能再来一次

Step1:创建虚拟环境

conda create -n gpuKeras python=3.6

Step2:进入虚拟环境，安装对应版本的cudatoolkit

conda install cudatoolkit=10.1

Step3:安装对应版本的cuDNN

conda install cudnn=7.2

Step4:安装指定版本的tensorflow-gpu

conda install tensorflow-gpu==1.12.0

接着可以输入python进入python环境查看是否可以正常导入tf模块，发现有警告,这是由于numpy的版本导致的，解决方案可以查看这个

  np_resource = np.dtype([("resource", np.ubyte, 1)])

Step5:安装keras

pip install keras==2.2.0

查看是否安装成功

也可以在cmd运行以下文件test_code.py
在文件路径下python test_code.py即可，我自己遇到的问题是，powershell报错（numpy版本的问题，实在是懒得改了，cmd够用了~）
文件内容如下：

# 忽略对机器的警告
import warnings
warnings.filterwarnings('ignore', category=FutureWarning)

# 查看GPU是否成功加载
from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())

from keras import backend as K
print(K.tensorflow_backend._get_available_gpus())
