WIN10+theano+CUDA+CUDNN安装配置及测试

一、基础准备

1.安装python
2.安装anaconda
3.在anaconda中安装theano

二、CUDA安装

1.下载CUDA和cudnn(版本一定要对应)
CUDA:https://developer.nvidia.com/cuda-downloads
cudnn:https://developer.nvidia.com/rdp/cudnn-archive
2.将cudnn压缩包中的文件复制到CUDA安装目录中,选择覆盖。
3.用CMD命令行中输入查询nvcc -V,如果能够正确显示版本信息就表明安装成功。

三、其他配置

1.在C:\Users\WP目录下创建文件“.theanorc.txt”
文件内容为:

device = cuda
floatX = float32

四、使用python测试是否为GPU运行

from theano import function, config, shared, tensor
import numpy
import time

vlen = 10 * 30 * 768  # 10 x #cores x # threads per core
iters = 1000

rng = numpy.random.RandomState(22)
x = shared(numpy.asarray(rng.rand(vlen), config.floatX))
f = function([], tensor.exp(x))
print(f.maker.fgraph.toposort())
t0 = time.time()
for i in range(iters):
    r = f()
t1 = time.time()
print("Looping %d times took %f seconds" % (iters, t1 - t0))
print("Result is %s" % (r,))
if numpy.any([isinstance(x.op, tensor.Elemwise) and
              ('Gpu' not in type(x.op).__name__)
              for x in f.maker.fgraph.toposort()]):
    print('Used the cpu')
else:
    print('Used the gpu')

若输出结果为:


测试输出结果

则表明环境配置成功。
