Splet14. avg. 2024 · It is the correct mathematical name for the operation. It would be helpful to provide library writers a mechanism to permute both NumPy-like arrays and PyTorch tensors. PyTorch uses transpose for transpositions and permute for permutations. It plans to implement swapaxes as an alternative transposition mechanism, so swapaxes and … Splet自定义了DataLoader，加入了输入特征个数、分类个数和torch.device(‘cuda:0’) 使用torch.utils.data.DataLoader记得import torch.utils.data 可显示代码参数; collate_fn有改进空间，如果多个三角网格面的个数不一致，可以用0填补以组成一个batch(对齐)
