WebAug 6, 2024 · Understand fan_in and fan_out mode in Pytorch implementation nn.init.kaiming_normal_ () will return tensor that has values sampled from mean 0 and variance std. There are two ways to do it. One way is to create weight implicitly by creating a linear layer. We set mode='fan_in' to indicate that using node_in calculate the std Webpytorch functions sparse DOK tensors can be used in all pytorch functions that accept torch.sparse_coo_tensor as input, including some functions in torch and torch.sparse. In these cases, the sparse DOK tensor will be simply converted to torch.sparse_coo_tensor before entering the function.
