我正在尝试将 tensorflow 模型转换为 OpenVINO IR 文件。我从以下地址下载了一个预训练模型：
http://download.tensorflow.org/models/object_detection/mask_rcnn_inception_v2_coco_2018_01_28.tar.gz
然后我提取文件得到一个名为“frozen_inference_graph.pb”的.pb文件然后我使用OpenVINO文件夹中的转换命令
“IntelSWTools\openvino_2019.2.275\deployment_tools\model_optimizer\”
如下：
python mo_tf.py --input_model frozen_inference_graph.pb
但我收到以下错误消息。我怎样才能修改任何东西来解决这个问题？

我尝试了许多其他 tensorflow 模型，但都有相同的问题。我使用了从1.2.0到1.14.0的不同 tensorflow 版本，但相同。
关于形状的关键词似乎是主要原因。但是我怎样才能添加一些东西来避免这个问题呢？

希望能正确生成IR文件。
