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...

当添加树突时,model将是包含新树突模块且保持原有权重的新架构。此时restructured变为true,需要重置优化器和调度器以指向新模型参数。addValidationScore函数的第三个输出trainingComplete表示追踪器是否确定额外树突不再提升性能。所有这些变量都需要从...
