It seems that x[:, :, masks] doesn't work since masks is a list of masks. Note, each mask has a different number of True entries, so simply slicing out the relevant elements from x and averaging is difficult since it results in a nested/ragged tensor.

Here’s a sample execution. WebJan 12, 2024 · Sorted by: 27. A tensor has multiple dimensions, ordered as in the following figure. There is a forward and backward indexing. Forward indexing uses positive integers, backward indexing uses negative integers. Example: -1 will be the last one, in our case it will be dim=2. -2 will be dim=1. -3 will be dim=0.

WebMay 24, 2024 · The MSE loss is the mean of the squares of the errors. You're taking the square-root after computing the MSE, so there is no way to compare your loss function's output to that of the PyTorch nn.MSELoss() function — they're computing different values.. However, you could just use the nn.MSELoss() to create your own RMSE loss function as:. … build a hat rackWebApr 11, 2024 · pytorch学习笔记1 开始学习Pytorch了,参考了网上大神的博客以及《深度学习之Pytorch实战计算机视觉》记录学习过程,欢迎各位交流。pytorch基础学习与环境搭建 PyTorch是美国互联网巨头FaceBook在深度学习框架Torch基础上用python重写的一个全新深度学习框架,功能与Numpy类似,但在继承Numpy多种优点之上 ... build a haven ltdWebJun 10, 2024 · This results in two Subset-Datasets: train_dataset and valid_dataset.
