我想在Windwos 8上安装Theano
已经遵循了these步骤。
我尝试使用:
import numpy as np
import time
import theano
print('blas.ldflags=', theano.config.blas.ldflags)
A = np.random.rand(1000, 10000).astype(theano.config.floatX)
B = np.random.rand(10000, 1000).astype(theano.config.floatX)
np_start = time.time()
AB = A.dot(B)
np_end = time.time()
X, Y = theano.tensor.matrices('XY')
mf = theano.function([X, Y], X.dot(Y))
t_start = time.time()
tAB = mf(A, B)
t_end = time.time()
print("NP time: %f[s], theano time: %f[s] (times should be close when run on CPU!)" % (
np_end - np_start, t_end - t_start))
print("Result difference: %f" % (np.abs(AB - tAB).max(), ))
我知道这个脚本是numpy和theano计算时间的比较。
但不知怎么的,有些dll没有找到。Pl找到以下日志:

ImportError: DLL load failed: The specified module could not be found.
作为python世界的新手,我无法找出哪个Dll在not found中。如果缺少,我将安装它,并将路径添加到系统路径变量。但我如何知道它是哪个dll。我尝试使用pdb
,并在cmodule.py
中的不同位置设置断点,但没有一个被命中。
theano
时走完全不同的路。我偶然发现一些帖子建议微软编译器工作得很好。但我已经坐在一个问题上,从过去14个小时连续,并希望一个方法,这是可行的。最终,我想要theano
在我的系统上。顺便说一下,没有CUDA
。我只在用CPU。
好吧,我终于找到了使用WinPython、python3.5.1.1、Win 7 64bit和mingw64安装的原因:
在.theanoc[.txt]文件中,在安装blas之后,我看到一个[blas]部分,其中有一行包括openblas include路径。我删除了那一行,把下面的区域留空。重新启动WinPython/Spider,打开一个新控制台,它工作了。
之后,使用Theano从千层面运行mnist.py进行测试。
可能有点晚了。我跟你一模一样地遵循着同样的指导,也遇到了同样的错误。
原来,可以通过将openblas目录添加到系统路径来修复它。在您的示例中,将“E:\ Things\u Installed\u Here\Theano\openblas”添加到系统路径变量。
请注意,根据放置DLL文件的位置,需要添加“E:\ Things\u Installed\Theano\openblas”或“E:\ Things\u Installed\Theano\openblas\bin”。
Windows1064位,Python3.5.1(Anaconda2.5),Theano0.8.2。
对于那些需要它的人,我可以在Windows 10中安装Theano,这要感谢这三个指南guide1,guide2和OP附带的指南
我也在努力让theano在Windows 10 x64上运行,在阅读了几本帮助指南之后,我最终得到了以下结果:
conda install mingw libpython
pip install theano
在.theanoc.txt中输入以下内容:
希望这能帮助别人。
