Python Tensorflow贡献后的Bazel构建和测试

我在tensorflow/tensorflow/python/ops/image_ops_impl.py中添加了功能，并在tensorflow/tensorflow/python/ops/image_ops_test.py中添加了相应的单元测试

我最初从主分支派生tensorflow，在本地机器上进行了这些更改，重新设置了基础并提交

然后我创建并激活了一个virtualenv

当运行bazel test//tensorflow/python…，正如我收到的贡献指南中所建议的那样：

请问我的问题的根源是什么

因为我只是在更改python功能，所以不需要重建

编辑：重新运行后。/configure:

编辑2：

在运行bazel clean-expunge之后。/configure:

编辑3：

完成以下步骤后：

是否可能在构建之前忘记运行./configure？

您好，是的，我以前运行过`./configure'，但我再试了一次。我现在的新输出失败了，请看上面。嗯，看起来有些bazel设置是在系统升级之前遗留下来的。您可以尝试bazel clean-expunge，然后重新运行配置，最后重试测试吗？尝试时没有运气，请参见上文！也许是这里的命令？谢谢，在遵循这些步骤之后，它现在开始构建。但是，仍然存在生成错误。我正在尝试：这种情况还会发生在头tf身上吗？
