你需要手动的必须要设置model的模式为train(), 每次设置的时候都需要手动重置一下. 然后我们train一下: deftrain_model(model,train_loader,test_loader,device,learning_rate=1e-1,num_epochs=200):# The training configurations were not carefully selected.criterion=nn.CrossEntropyLoss()model.to(device)...
def prepare_model(model): model.train() model.qconfig = torch.quantization.get_default_qat_qconfig('fbgemm') model = torch.quantization.fuse_modules( model, [ # NOTE(aleksey): 'features' is the attr containing the non-head layers. ['features.in_conv.conv2d', 'features.in_conv.batchnorm...

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。
