Tensorflow Lite模型未检测到物体，有时会发生碰撞

Question

系统信息 **操作系统平台和发行版**：Linux Ubuntu 18.04和Windows 10 TensorFlow安装自（源或二进制）：二进制 TensorFlow版本（使用下面的命令）：1.9.0 CPU Bazel版本（如果从源代码处编译）：0.11.1

你好，我按照下面的steps来训练我的tensorflow模型ssd\u mobilenet\u v1\u coco（tf记录和env准备是用这个tutorial完成的）

所有这些都是在windows10上完成的，即使在Tensorflow的Android应用程序上，这个模型也运行良好 然后为了导出到TF-lite格式，我将.pb文件发送到一个Ubuntu dist和FLOAT命令used

当我尝试在tensorflow lite android应用程序上运行模型时，我按照here的说明添加了一个自定义模型，但是我的模型没有检测到任何东西。当我试图按音量下降按钮“调试”的推断，应用程序崩溃。这是我的相关android堆栈：
