Python Azure表单识别器组合模型错误

我正在尝试使用azure ai FormRecognitor==3.1.0b1在python 3.8.5中创建一个组合模型

我最近重新训练了其中一个子模型，现在我在尝试创建更新的组合模型时收到以下错误：

azure.core.exceptions.HttpResponseError: (3200) Internal error during model reading for model f13d268e-336e-4104-9625-ad0a5463dc82.
Invalid model created with ID=7909e991-8f39-4605-9558-eda89291ddb9

id为f13d268e-336e-4104-9625-ad0a5463dc82的型号工作正常，但是，当我单独使用时。下面是我可以从中下载的模型的json

正如您所看到的，它本身并不是一个组合模型。它以前可以写得很好。我最近用一些新的训练例子对它进行了再训练

---

有什么想法吗？

我更新到azure ai FormRecognitor==3.1.0b4，现在合成模型已正确创建
