Question

我已经完全以mnist.pkl.gz文件的形式转换了我的数据集，它运行了Theano deeplearning教程PDF（蒙特利尔大学）中给出的logistic_sgd.py和mlp.py程序。但是，在运行CNN.py文件时，它会产生一个很难理解的巨大错误。任何成功运行CNN.py程序以获取不同数据集的人都可以帮助我，因为我完全不知道错误是什么。我的训练集有1176个条目，我的验证和测试集各有168个条目。也许问题在于批量大小。如果是这样，有人可以建议我适当的批量大小吗？

我正在使用Anaconda Bundle附带的Spyder GUI for Python 2.7。

打印＆＃39; ...构建模型＆＃39;

后很快就会出现错误

代码段：

print '... building the model'

# Reshape matrix of rasterized images of shape (batch_size, 28 * 28)
# to a 4D tensor, compatible with our LeNetConvPoolLayer
# (28, 28) is the size of MNIST images.
layer0_input = x.reshape((batch_size, 1, 28, 28))

# Construct the first convolutional pooling layer:
# filtering reduces the image size to (28-5+1 , 28-5+1) = (24, 24)
# maxpooling reduces this further to (24/2, 24/2) = (12, 12)
# 4D output tensor is thus of shape (batch_size, nkerns[0], 12, 12)
layer0 = LeNetConvPoolLayer(
    rng,
    input=layer0_input,
    image_shape=(batch_size, 1, 28, 28),
    filter_shape=(nkerns[0], 1, 5, 5),
    poolsize=(2, 2)
)

发生错误时立即在控制台提示：

... bulding the modelWARNING (theano.gof.compilelock): Overriding existing lock by dead process '4396'(I am process '3624')
WARNING:theano.gof.compilelock:Overriding exisiting lock by dead process '4396' (I am process '3624')

然后会出现以下错误消息。

错误讯息：

Answer 1

我鼓励您添加更多信息（感谢您），因此我觉得有义务尽我所能，但不幸的是，这可能并不多。希望其他人可以添加更好的答案。

我认为您提供的代码段中不会发生错误。是的，它是在'...构建模型'消息之后，但我认为它还在继续。它可能会在theano.function调用时生成错误。

您的问题似乎出现在系统的C ++工具链中。我建议搜索有关“未定义的__imp_PyExc_ImportError引用”消息的更多信息。

例如，this StackOverflow question建议在命令行中添加-D MS_WIN64。但这可能是一个内部命令行，而不是您最初使用的命令行。

我不明白为什么它适用于一个数据集但不适用于另一个数据集。

Answer 2

我的笔记本电脑只有一些问题。它在另一台计算机上运行良好。

无法为另一个数据集
