Error initializing model :Microsoft.ML.OnnxRuntime.OnnxRuntimeException

I encountered a problem while using ML.NET

An error occurred while calling ONNX for an open source project, and I don't know how to handle it

System.InvalidOperationException:“Error initializing model :Microsoft.ML.OnnxRuntime.OnnxRuntimeException: [ErrorCode:Fail] Deserialize tensor transformer.word_embeddings.weight failed.open file transformer.word_embeddings.weight fail, errcode = 2 - ϵͳ�Ҳ���ָ�����ļ���
