【问题描述】：
我正在尝试在 Windwos 8 上安装 Theano
已遵循these 的步骤。
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(), ))
我知道脚本是 numpy 和 theano 计算时间之间的比较。
但不知何故，找不到某些 dll。请找到以下日志：

ImportError: DLL load failed: The specified module could not be found.
作为python世界的新手，我无法找出未找到哪个Dll。如果丢失，我会安装它，并将路径添加到系统路径变量中。但是我怎么知道它是哪个dll。我尝试使用pdb 并在cmodule.py 的各个位置设置断点，但没有一个被击中。
- 您是否熟悉此类错误及其解决方法？
- 否则，请帮我找到丢失的 dll 名称，剩下的事情我来做。
- 我不介意在安装
theano时走一条完全不同的路。我遇到了一些建议微软编译器工作得很好的帖子。但是自从过去 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。最终我想在我的系统上使用theano。
顺便说一句，没有CUDA。我只在 CPU 上尝试。

您好。在这里遇到同样的问题。真的，Windows 64bit 上的 theano 是一场灾难。一个问题接踵而至，如果您的部门只是不使用/允许 linux，还有什么选择？
