我正在根据contributing guidelines运行TensorFlow的单元测试。在我的本地macOS计算机上，由于an issue with apt-key，Docker镜像无法编译。我在Azure上设置了Docker on Ubuntu Server虚拟机（Standard A1 (1 Core, 1.75 GiB memory)），并运行了以下命令：
git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow/
tensorflow/tools/ci_build/ci_build.sh CPU bazel test //tensorflow/...
我的第一次尝试在最后的这些行崩溃了：

我的第二次尝试达到了配置的更多目标，但运行一个小时后似乎停滞了，因为它现在正在逐一增加目标：

TensorFlow单元测试需要运行多长时间？是否有人成功在Azure上运行它们？如果是，您使用了哪个映像和计算机？
