由于符号链接，Tensorflow lite 构建在 Windows 上失败

Question

我正在尝试为 Windows 10 构建tensorflow lite 2.16.2 (c++)，当我运行此命令时出现此错误

bazel build -c opt //tensorflow/lite:tensorflowlite

我已经安装了 msys2，添加到路径，安装 bazel 6.2.1 并将其添加到路径，在我的机器上安装 LLVM，运行

python ./configure.py

对一切说“不”，最后运行 bazel 构建命令。

当我运行它时，出现以下错误：

我在最后看到权限错误，并尝试以管理员身份运行cmd，但没有成功。我不知道 chmod 的 Windows 等效项以及要提供给哪个文件夹。

我还尝试使用以下命令启用开发人员模式：

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock" /t REG_DWORD /f /v "AllowDevelopmentWithoutDevLicense" /d "1"

我可以做什么来解决这个问题？

Answer 1

第一件事 - 只是确保编辑注册表后重新启动？

接下来我会尝试在 GUI 中启用开发者模式。

如果您无法让开发人员模式工作，那么我个人会尝试使用

--nowindows_enable_symlinks

（startup 标志）并使用

--noenable_runfiles

禁用运行文件。然而，这违背了张量流中的这个评论

.bazelrc

，所以如果你正在构建 pip 包的话，YMMV。
