我已经在项目中添加了agconnect文件。远程翻译工作正常。任何帮助都非常感谢谢谢。
屏幕截图：异常
Detailed LogFile:
【问题讨论】：
hi@waheed shah，能否分享一下问题发生时得到的详细日志？ hi@shirley，感谢您的回复。我添加了屏幕截图和详细的 logcatFile 以供参考。请查看并建议我解决方案。 @waheed shah 你能提供你看到的异常的日志吗？这将有助于解决问题。如果您能看到错误代码，您可以参考设备上的模型下载错误代码来排除错误。以下是定义：developer.huawei.com/consumer/en/doc/development/… @waheedshah 我正在调查您的问题，会尽快更新您的信息 @Zinna 好的，等待解决方案。 【参考方案1】：日志显示下载的翻译语言为en_en，调用接口时找不到对应的接口。
所以你可以尝试更改以下代码：
val sourceLangCode = "en"
到
val sourceLangCode = "zh"
【讨论】：
我添加了 "Log.d("SourceLang", "obtainModel: $model.languageCode")" 来检查正在获取什么。我将 en-US 作为语言代码，但问题仍然存在。当我从“en-US”更改为“zh”时。模型开始下载。为什么它不适用于“en-US”？ 界面中没有找到下载翻译语言en_en。因此，会报告错误。您可以在日志文件中搜索关键字“translation”并查看下载的翻译语言 en_name。 This picture 是哪里出了问题。 实际上，最初我添加了带有 null 值的 sourceCode，我得到了错误。然后，我已更改为您在图片中显示的内容。最后我将语言代码添加为“en-US”，但问题仍然存在。型号“en-US”不可用吗？ 型号“en-US”不是 ISO 639-1 格式。下载模型的格式为“en_name”，“en_name”前面的“en”不能更改。你只需要设置“name”，“name”就是“sourceLangCode”。使用 ISO 639-1。例如，如果要将德语转换为俄语，则需要下载“en_de”和“en_ru”模型。以上是关于华为机器学习套件下载模型时出现异常的主要内容，如果未能解决你的问题，请参考以下文章
