如何摆脱错误 "Fatal signal 11 (SIGSEGV), code 1, fault addr 0x70"
How to get rid of the error "Fatal signal 11 (SIGSEGV), code 1, fault addr 0x70"
我正在做我的 android 项目。基本上，用户输入一段文本，然后模型预测它是否具有冒犯性。这是通过在 python 上训练深度学习模型 LSTM 完成的。然后我将它部署到云端 (Firebase)。并将其下载到我的 android phone 中，如果已下载，则从远程模型创建一个解释器。现在，当我尝试 运行 应用程序时，模型是从云端下载的，但它给出了一个错误。错误消息的 PFA 屏幕截图。
让我知道我做错了什么以及为什么会出现这样的错误？
这是我运行应用程序时得到的日志，

这似乎是tensorflow-lite 库内部问题。您的代码似乎工作正常，因为日志中记录了以下语句："succed to build FirebaseModelInterpreter"，这意味着 onSuccessListener 工作正常。之后在初始化tensorflow lite runtime时出现问题，错误是libc错误，似乎起源于OS级别，显然是由于某些非法内存访问。在我看来，这只能归因于 tensorflow-lite 库本身。您可以尝试使用不同版本的库或不同的设备，但我不能确定。
在 gradle 文件中：
尝试更改
实施'org.tensorflow:tensorflow-lite:2.0.0'
至
实施'org.tensorflow:tensorflow-lite:+'

这似乎是tensorflow-lite 库内部问题。您的代码似乎工作正常，因为日志中记录了以下语句："succed to build FirebaseModelInterpreter"，这意味着 onSuccessListener 工作正常。之后在初始化tensorflow lite runtime时出现问题，错误是libc错误，似乎起源于OS级别，显然是由于某些非法内存访问。在我看来，这只能归因于 tensorflow-lite 库本身。您可以尝试使用不同版本的库或不同的设备，但我不能确定。
在 gradle 文件中：
尝试更改
实施'org.tensorflow:tensorflow-lite:2.0.0'
至
实施'org.tensorflow:tensorflow-lite:+'
