阿诺断言

Question

当我运行Theano并想训练二维卷积网络时，我得到以下错误：

ERROR (theano.gof.opt): Optimization failure due to: local_abstractconv_check
ERROR (theano.gof.opt): node: AbstractConv2d{border_mode='half', subsample=(1, 1), filter_flip=True, imshp=(None, None, None, None), kshp=(32, 3, 3, 3), filter_dilation=(1, 1)}(convolution2d_input_1, convolution2d_1_W)

AssertionError: AbstractConv2d Theano optimization failed: there is no implementation available supporting the requested options. Did you exclude both "conv_dnn" and "conv_gemm" from the optimizer? If on GPU, is cuDNN available and does the GPU support it? If on CPU, do you have a BLAS library installed Theano can link against?

我在python3.4中安装了Anaconda（包括MKL）和最新版本的Theano。我还安装了mingw和libpython。我检查了BLAS的存在_布拉斯比由Theanom提供的脚本，其中说Theano通过numpy连接到BLAS。在

我现在不知道什么是错误的，仍然（显然）希望优化器工作。我在网上看到了一些关于这个问题的帖子，但是除了安装其他东西或者不使用优化器之外，没有一个真正的解决方案。有人知道如何防止这种错误吗？在
