假设我们有 2 个副本,那么每个进程拥有的train_set 将包括 60000 / 2 = 30000 个样本。我们还将批量大小除以副本数,以保持整体批量大小为 128。 我们现在可以编写常见的前向后向优化训练代码,并添加一个函数调用来平均我们模型的梯度(以下内容主要受PyTorch MNIST官方示例的启发)。 代码语言:javascript 代码运行次数...

在先决条件部分,我们提供了训练脚本 pytorch_train.py。 实际上,你应该能够原样获取任何自定义训练脚本,并使用 Azure 机器学习运行它,而无需修改你的代码。 提供的训练脚本会下载数据、训练模型并注册模型。 生成训练作业 现在你已拥有运行作业所需的所有资产,是时候使用 Azure 机器学习 Python SDK v2 进行生成了。
