模型第三次在train模式下inference,输出结果output_train2和第一次结果output_train相同,原因是train模式下BN参数由输入数据计算得出,两次input相同则output相同(此时model保存的默认均值方差再次更新); 模型第四次在eval模式下inference,输出结果output_eval2和第二次结果output_eval不同,原因是在第三次train模式下inferen...
This section describes how to create an image and use the image for training on the ModelArts platform. The AI engine used for training is PyTorch, and the resources are

It's important to callmodel.eval()ormodel.train(False)before exporting the model, as this sets the model toinference mode. This is needed since operators likedropoutorbatchnormbehave differently in inference and training mode. To run the conversion to ONNX, add a call to the conversion functi...
