無法在 android 上部署 ssd mobilenet v1 fpn

Question

我正在使用默認 ssd mobilenet v1 fpn model 進行 object 檢測。 它在我的筆記本電腦上運行得非常好，但是當我嘗試在 android 上部署 tflite 文件時，它給了我錯誤：

A/libc：致命信號 6 (SIGABRT)，tid 25346 中的代碼 -6（推理）

但是當我使用 ssd mobilenet v1 時，該應用程序運行得非常好

誰能指導我該怎么做？ 任何幫助都會很棒

Answer 1

在 android 上部署 ssd mobilenet v1 fpn 存在一些問題。

請參考 TF API 中的未解決問題（ https://github.com/tensorflow/models/issues/5298 ）
