Python 通过logic app上的函数部署AZURE自定义标签表单模型
我使用标签工具来训练自定义模型。该工具提供了一个用于使用它的python脚本。它在终点站运行良好。现在我想把它放在逻辑应用程序中的Azure函数中。pdf电子邮件附件将触发表单分析器模型，然后我将解析JSON响应。到目前为止，我还无法：Python 通过logic app上的函数部署AZURE自定义标签表单模型,python,azure,Python,Azure,我使用标签工具来训练自定义模型。该工具提供了一个用于使用它的python脚本。它在终点站运行良好。现在我想把它放在逻辑应用程序中的Azure函数中。pdf电子邮件附件将触发表单分析器模型，然后我将解析JSON响应。到目前为止，我还无法： 已在Azure函数中成功部署提供的脚本 在一个逻辑应用程序中使用它来识别我将存入blob或通过电子邮件发送的每个pdf 这是Azure表单识别器工具提供的脚本： ########### Python Form Recognizer Async Analyze #
