使用带有lasagne NeuralNet的Conv2DLayer时出错
作者：互联网
我有Windows 8.1 64位并使用推荐这里http://deeplearning.net/software/theano/install_windows.html#installing-theano python win-python发行版(python 3.4).我已经完成了教程的每一步(不包括CUDA的东西和GPU配置),卸载了所有内容并再次完成,但我的问题仍然存在.我正在尝试使用烤宽面条构建卷积神经网络.到目前为止我测试的每一层都在工作 – 只有Conv2DLayer会抛出错误.代码如下：
net2 = NeuralNet(
layers=[
('input', layers.InputLayer),
('conv1', layers.Conv2DLayer),
('pool1', layers.MaxPool2DLayer),
('hidden4', layers.DenseLayer),
('hidden5', layers.DenseLayer),
('output', layers.DenseLayer),
],
input_shape=(None, 1, 96, 96),
conv1_num_filters=32, conv1_filter_size=(3, 3),
pool1_pool_size=(2, 2),
hidden4_num_units=500, hidden5_num_units=500,
output_num_units=30, output_nonlinearity=None,
update_learning_rate=0.01,
update_momentum=0.9,
regression=True,
max_epochs=400,
verbose=1,
)
下面我贴了我得到的错误.我想gcc有些问题(我从教程中得到了确切版本),但无法确定问题是什么.我有最新版的千层面/ theano.我已经尝试过Anaconda和WinPython发行版.我已经尝试过使用python 2.7和3.4,并且无法找到解决此问题的任何方法.只有密集/ maxPooling层的网络运行得很好.如果有任何建议可以帮助我解决这个问题,我将不胜感激.

解决方法:
我设法通过遵循IshanAntony在本网站https://www.kaggle.com/c/otto-group-product-classification-challenge/forums/t/13973/a-few-tips-to-install-theano-on-windows-64-bits/98833上给出的步骤来解决我的问题.显然Theano有正确连接BLAS的问题所以我下载并使用了open-BLAS并且错误消失了(下载和配置OPEN-BLAS所需的链接和步骤可以在IshanAntony的答案中找到).
