TF版本为1.9.0，cython版本为0.28.4，import tensorflow.contrib.layers as layers时出现错误，

我认为 Cython 的版本有问题，但我不确定。我该如何解决？

【解决方案1】：

现在，我不知道这个错误是如何产生的，但仍然有一个解决方法是使用tf.layers.dense 来替换它

tf.layers.dense(...) # tf.contrib.layers.fully_connected(...)

当您没有更新依赖项的 root 权限时，此错误很糟糕。

参考：

Are tf.layers.dense() and tf.contrib.layers.fully_connected() interchangeable?
