Android Tensorflow Lite模型未检测到物体，有时会发生碰撞

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

您好，为了训练我的tensorflow型号ssd_mobilenet_v1_coco，我遵循了以下步骤（tf记录和env准备都是用这个完成的）

所有这些都是在Windows10上完成的，该模型运行良好，即使在Tensorflow Android应用程序上也是如此 然后为了导出为TF-lite格式，我将.pb文件发送到Ubuntu dist和FLOAT命令

当我尝试在tensorflow lite android应用程序上运行模型时，我的问题出现了，我按照说明添加了一个自定义模型，但我的模型没有检测到任何东西。当我试图按下音量下降按钮“调试”时，推断应用程序崩溃。这是我的相关android堆栈：

这可能是检测器创建的问题，如果无法找到或正确加载模型，则可能会发生此问题。您应该查看

adb logcat

，以查看
