在 Windows 上安装 Theano - DLL 加载失败

我正在尝试在 Windows 8 上安装 Theano

已关注these steps.

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。

但不知何故，有些dll找不到。请找到以下日志：

作为Python世界的新手，我无法找出未找到哪个Dll。如果缺少，我会安装它，并将路径添加到系统路径变量中。但是我如何知道它是哪个dll呢？我尝试使用pdb并设置断点cmodule.py在不同的地点，但没有一个被击中。

1. 您熟悉这种错误及其解决方法吗？
2. 否则，请帮我找到丢失的 dll 名称，我将完成剩下的工作。
3. 我不介意在安装时走完全不同的道路theano。我看到几篇文章表明微软编译器工作得很好。但自过去 14 小时以来，我已经连续遇到一个问题，并且想要一种有效的方法。最终我想要theano在我的系统上。

顺便说一句，没有CUDA。我只在CPU上尝试。

这可能有点晚了。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它。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，根据您放置 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，我能够在 Windows 10 中安装 Theanoguide1, guide2以及OP附带的指南。
