I am declaring a class to have an array of 8 function pointers of the signature "void functionname()". When I declare and initialize an object of the class inmainasMyTest testObj = {};orMyTest testObj;, I expected it to be zero-initialized, i.e. all pointers are null pointers. ...
struct S { void *operator new (unsigned int size, void*p, int i) { ((S*)p)->i = i; return p; } int i; }; struct T { int i; char c; }; class C { T t; int i; public: C(): t(), i() {} // Zero initializes members of class. }; // Zero initialize members ...

To zero-initialize an object of type T means: — if T is a scalar type (3.9), the object is set to the value of 0 (zero) converted to T; — if T is a non-union class type, each nonstatic data member and each base-class subobject is zero-initialized; — if T ...
Describe the bug The same issue as #3228, except for stage3 with zero init To Reproduce Steps to reproduce the behavior: Install accelerate and transformers from source w/ the new Accelerate trainer integration (pip install git+https://g...
deepspeed.initialize返回的model.network是经过DS包装过的engine类型,不过其与nn.module类型api兼容,所以可以像torch一样进行前向传播。不过在反向传播时,则需要手动调用模型的backward反向传播梯度和step更新模型参数: # train loop for _, batch_index in enumerate(tqdm(dataset_iterator, smoothing=1)): try: batch...
Describe the bug I am tryiny to train FLAN-T5-XL using DeepSpeed zero 3 and transformers and it seems z3/ cpu offload seems to use quite a lot of gpu memory as compared to the expectations. I am running on 4x V100 16GB. And i ran the est...
model_engine, _, _, _ = deepspeed.initialize( model=model, model_parameters=model.parameters(), config=deepspeed_config ) print(f"Device {rank} - ZeRO Stage: {model_engine.zero_optimization_stage()}") 要启动分布式训练作业,我们使用与 deepspeed Python 软件包一起安装的 deepspeed 命令行实用程序...
若要在 Windows 10 版本 2004 之前的 Windows 版本上运行,驱动程序必须在调用此函数之前定义POOL_ZERO_DOWN_LEVEL_SUPPORT并调用 ExInitializeDriverRuntime。此函数与 ExAllocatePoolWithTag 之间的唯一区别是内存初始化为零。 如果不需要,请改用 ExAllocatePoolUninitialized,这是 ExAllocatePoolWithTag 的包装器。
