Python_2019-02-26_机器学习——Win10 nvidia cuda cudnn tensorflow-gpu

参考(可以成功):https://blog.csdn.net/jacke121/article/details/78960658

win10:189版本

nvidia418:C:\NVIDIA\DisplayDriver\418.91\Win10_64\International

cuda10:C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0

cudnn7.5:复制到cuda

tensorflow-gpu:pip install tensorflow-gpu

最后安装的版本为1.13.1-gpu版本可行

更新:pip install --upgrade tensorflow-gpu

验证:import tensorflow as tf   tf.__version__

安装失败:

pip install tensorflow-1.12.0rc0-cp36-cp36m-win_amd64.whl
Successfully installed tensorboard-1.11.0 tensorflow-1.12.0rc0

程序测试:

import sys
import numpy as np
import tensorflow as tf
from datetime import datetime

device_name = sys.argv[1]  # Choose device from cmd line. Options: gpu or cpu
shape = (int(sys.argv[2]), int(sys.argv[2]))
if device_name == "gpu":
    device_name = "/gpu:0"
else:
    device_name = "/cpu:0"

with tf.device(device_name):
    random_matrix = tf.random_uniform(shape=shape, minval=0, maxval=1)
    dot_operation = tf.matmul(random_matrix, tf.transpose(random_matrix))
    sum_operation = tf.reduce_sum(dot_operation)


startTime = datetime.now()
with tf.Session(config=tf.ConfigProto(log_device_placement=True)) as session:
        result = session.run(sum_operation)
        print(result)

# It can be hard to see the results on the terminal with lots of output -- add some newlines to improve readability.
print("\n" * 5)
print("Shape:", shape, "Device:", device_name)
print("Time taken:", datetime.now() - startTime)

print("\n" * 5)

##______________
gpu:
python matmul.py gpu 1500
cpu:
python matmul.py cpu 1500

指定gpu运行:

# 新建一个 graph.
import tensorflow as tf
a = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[2, 3], name='a')
b = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[3, 2], name='b')
c = tf.matmul(a, b)
# 新建session with log_device_placement并设置为True.——运行gpu
sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))
# 运行这个 op.
print(sess.run(c))

 pip国内镜像

对于Python开发用户来讲,PIP安装软件包是家常便饭。但国外的源下载速度实在太慢,浪费时间。而且经常出现下载后安装出错问题。所以把PIP安装源替换成国内镜像,可以大幅提升下载速度,还可以提高安装成功率。
国内源:
新版ubuntu要求使用https源,要注意。
清华:https://pypi.tuna.tsinghua.edu.cn/simple
阿里云:http://mirrors.aliyun.com/pypi/simple/
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/
华中理工大学:http://pypi.hustunique.com/
山东理工大学:http://pypi.sdutlinux.org/ 
豆瓣:http://pypi.douban.com/simple/
临时使用:
可以在使用pip的时候加参数-i https://pypi.tuna.tsinghua.edu.cn/simple

例如:pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pyspider,这样就会从清华这边的镜像去安装pyspider库。
 
永久修改,一劳永逸:
Linux下,修改 ~/.pip/pip.conf (没有就创建一个文件夹及文件。文件夹要加“.”,表示是隐藏文件夹)
内容如下:
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host=mirrors.aliyun.com
windows下,直接在user目录中创建一个pip目录,如:C:\Users\xx\pip,新建文件pip.ini。
内容如下:
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host=mirrors.aliyun.com
