我将最新版本的tensorflow安装到Anaconda虚拟环境中。运行 Hello World 测试会出现 OpKernel 未知操作错误。这就像 TensorFlow version 1.0.0-rc2 on Windows: "OpKernel ('op: "BestSplits" device_type: "CPU"') for unknown op: BestSplits" with test code ，但修复方法是运行夜间构建以避免 1.0.0-rc2 中出现问题。
我的版本是 #116(2017 年 3 月 18 日凌晨 2:25:00)tensorflow-1.0.1-cp35-cp35m-win_amd64.whl，其中应包含上述修复。看来唯一的后续构建(#117 Mar 19, 2017 2:25 AM)失败了。我已将我的 session 日志粘贴在下面。

最佳答案
此问题已在 master 中修复TensorFlow 的分支，但修复不在 r1.0 中发布分支，从该分支发布了 1.0 和 1.0.1 版本。它将出现在下一个版本 (1.1) 中，但现在您可以选择忽略错误消息(幸运的是，这些消息是无害的)从源代码编译，或使用夜间构建。
