当我使用gpu支持构建tensorflow时（在configure中我将cuda支持设置为yes），bazel build -c opt --config = cuda // tensorflow / tools / pip_package：build_pip_package一切正常 .
但在我重启系统后，尝试使用上面的命令构建tensorflow，它会给我以下错误：
错误

bazel构建检查环境变量TF_NEED_CUDA是否设置为1，否则会报告 . 此变量在configure脚本中导出，但在重新引导后丢失 .
在构建之前执行
export TF_NEED_CUDA=1可能会解决您的问题，但重启后可能还有其他环境变量或文件丢失 .
