支持对象检测API中的Tensorflow 2.0

Question

我正在使用TF Object Detection API来训练我最终将使用tf-serving部署的模型。我计划获取此网络的输出（在中间CNN层）并为对象检测之外的其他功能构建其他网络。我打算在TF 2.0中开发新的网络。但是，为了顺利工作，（我怀疑）需要更新Object Detection API以支持TF-2.0。

是否有计划将TF OD API更新为TF 2.0？

我尝试运行model_builder_test并且它失败，如下所示，因为tensorflow 2.0不再支持contrib。

Traceback (most recent call last):

    from object_detection.builders import model_builder

Tensorflow 2.0仍处于Alpha状态。幸运的是，最终将添加对Tensorflow 2.0的支持。看到这个issue
