在PyTorch中,通用的数据结构tensor包含一个attributerequires_grad,它被用于说明当前量是否需要在计算中保留对应的梯度信息,以上文所述的线性回归为例,容易知道参数www为需要训练的对象,为了得到最合适的参数值,我们需要设置一个相关的损失函数,根据梯度回传的思路进行训练。
当我们尝试计算模型参数的梯度时,PyTorch(或其他深度学习框架)会构建一个计算图(Computational Graph),用于记录计算过程中的所有操作。计算图是动态构建的,它所记录的操作将用于反向传播计算梯度。 然而,有些操作可能会改变变量的值,并且需要在计算图中记录这种改变。但是,如果我们进行原地(inplace)操作,实际上会改变原...
Comgra helps you analyze and debug neural networks in pytorch. It records your network internals, visualizes the computation graph, and provides a GUI to investigate any part of your network from a variety of viewpoints. Move along the computation graph, check for outliers, investigate both indiv...
在PyTorch中,如何实现局部禁用梯度计算? The context managers torch.no_grad(), torch.enable_grad(), and torch.set_grad_enabled() are helpful for locally disabling and enabling gradient computation. See Locally disabling gradient computation for more details on their usage. These context managers are...
DHG also integrates commonly used Laplacian matrices and messagepassing functions into the graph/hypergraph structure. Once a structure is built with DHG, these functions become readily available for use in model development. Fig. 15 shows the primary function library of DHG, built upon PyTorch, ...
Dragon actively tracks the release ofPyTorchandTensorFlow, dispatches AI computation on diverse accelerators, including the newest NVIDIA GPUs and Apple Silicon processors. It is the first deep learning framework that focuses on developing multiple styles, rather than promoting private interface. We will...
No matter the static graph (e.g., TensorFlow) or the dynamic graph (e.g., PyTorch), the inference process needs to parse the inference computing graph, and construct the execution graph to invoke multiple kernel functions. Currently, most deep learning frameworks use kernel functions in acceler...
comment: 感觉目前 pytorch 已经有这个功能了,这个不太确定?文章的实现是基于 RAF (TVM) 这个 baseline 不确定其优化。然后是 MoE 架构的假设,如下图,先计算 FFN 梯度(左侧),上一层才是替换 FFN 的专家层(右侧)。 难道用的模型是 FFN 和专家层交替的?如果画成左侧一开始就是$dX_{ffn}$应该也不影响重叠...
