从tensorflow转Pytorch的笔记(gather的用法,待补充...)
WebTensor. Tensor,又名张量,读者可能对这个名词似曾相识,因它不仅在PyTorch中出现过,它也是Theano、TensorFlow、 Torch和MxNet中重要的数据结构。. 关于张量的本质不乏深度的剖析,但从工程角度来讲,可简单地认为它就是一个数组,且支持高效的科学计算。. 它 … WebApr 13, 2024 · 在学习 CS231n中的NetworkVisualization-PyTorch任务,讲解了使用torch.gather函数,gather函数是用来根据你输入的位置索引 index,来对张量位置的数据进行合并,然后再输出。其中 gather有两种使用方式,一种为 ... bourbon ugly sweaters

WebBasically, PyTorch backward function contains the different parameters as follows. Tensor. backward ( specified gradient = none, specified gain graph = false, specified input = none)[ required sources] Explanation By using the above syntax we can implement the PyTorch backward function, here we use different parameters as shown in the above syntax. Weball_gather LightningModule. all_gather ( data, group = None, sync_grads = False) [source] Gather tensors or collections of tensors from multiple processes. This method needs to be called on all processes. Failing to do so will cause your program to stall forever. Parameters Webtorch.autograd.backward(tensors, grad_tensors=None, retain_graph=None, create_graph=False, grad_variables=None, inputs=None) [source] Computes the sum of gradients of given tensors with respect to graph leaves. … bourbon up
