python - 在Windows上安装Theano-DLL加载失败

我正在尝试在Windwos 8上安装Theano

遵循了these的步骤。

我尝试使用以下方法进行测试:

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(), ))

我知道该脚本是numpy和theano计算时间之间的比较。

但是不知何故，找不到某些dll。 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，我无法找出未找到的Dll。如果缺少它，我会安装它，并将路径添加为系统路径变量。但是我如何知道它是哪个dll。我尝试使用pdb并在cmodule.py中的各个位置设置了一个断点，但是没有一个命中。

您是否熟悉这种错误及其解决方案？

否则，请帮助我找到缺少的dll名称，剩下的我会做。

我不介意在安装theano时走完全不同的道路。我碰到过几篇文章，暗示Microsoft编译器可以正常工作。但是自从过去14个小时以来，我已经一直处于一个问题上，并且想要一种可行的方法。最终，我希望在系统上使用theano。

顺便说一句，没有CUDA。我只在CPU上尝试。

最佳答案

这可能会晚一点。我遵循与您完全相同的指南，并遇到了相同的错误。

事实证明，可以通过将openblas目录添加到系统路径来修复该问题。在您的示例中，将“E:\Things_Installed_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，您需要添加“E:\Things_Installed_Here\Theano\openblas”或“E:\Things_Installed_Here\Theano\openblas\bin”。

Windows 10 64位，Python 3.5.1(Anaconda 2.5)，Theano 0.8.2。

对于那些需要它的人，由于这三个指南guide1，guide2和OP随附的指南，我能够在Windows 10中安装Theano。
