我是 Theano 的新手。遵循本指南后：http : //deeplearning.net/software/theano/install_windows.html#install-windows 我设法正确使用 theano。后来我升级到 theano dev 版本，现在我不断收到这个异常：
import theano
........... cuda_ndarray.cu printed out........

我毫无疑问地发现，出于某种原因，来自 .theanorc 的 FLAGS 被调用了两次，如果我在 .theanorc 中放了两次，我会在异常中得到 4 次。但我不知道那些两次提到的标志在哪里。这个 theano-nvcc-cuda- 怎么样？连锁工作？谁在调用 nvcc 并导致此问题？
顺便说一句，如果我不指定 cl-version，我会得到
