Mseloss loss function is called in Chinese. The formula is as follows: Here, the loss, X, and y dimensions are the same. They can be vectors or matrices, and I is a subscript. Many loss functions have two Boolean parameters: size_average and reduce. Generally, the loss function directly calculates the batch data. Therefore, the returned loss result is a vector with the dimension (batch_size. The general format is as follows: loss_fn = torch.nn.MSELoss(reduce=True, size_average=True) Note the fo

Most of the Pytorch introductory tutorials are trained and tested using the data in the torchvision. If we are our own picture data, how to do it. one, my data When I was studying, I used the fashion-mnist. This data is relatively small, my computer does not have the GPU, but also can feel all. About Fashion-mnist data, can Baidu, also can point this to understand, the data is like this look: Download Address: Https://github.com/zalandoresearch/fash

This article is void My next installment is the TensorFlow and Keras truth. Environment: Anaconda4.2;python3.5;windows10,64,cuda Previous hard cuda9.1 useless, we want to use the GPU must choose cuda8.0, I thought the official will be corresponding update, naive. First TensorFlow don't recognize, moreover cudnn own all do not recognize, only 8.0. Keras and TensorFlow are both Pip,pytorch and OpenCV are going to find WHL. About Keras backend and inst

Sometimes we use other tasks (such as classification) to pre-train the network, then fix the convolutional layer as an image feature extractor, and then use the current task's data to train only the fully connected layer. So pytorch how to fix the bottom only update the upper layer when training. This means that we want to calculate the gradient in reverse propagation, we only want to compute to the topmost convolution layer, for the convolution layer

Pytorch Detach and Detach_ Pytorch's Variable object has two methods, detach and Detach_ This article mainly describes the effect of these two methods and what can be done with these two methods. Detach This method is described in the official documentation. Returns a new Variable that is detached from the current diagram. The returned Variable will never need a gradient if the detach Variable volatile=true, then detach out of the volatile is also tr

When using Pytorch's RNN module, it is sometimes unavoidable to use pack_padded_sequence and pad_packed_sequence, when using two-way RNN, you must use Pack_padded_seque NCE ! Otherwise, the Pytorch is unable to obtain the length of the sequence, and it does not correctly calculate the results of the bidirectional rnn/gru/lstm. However, there is a problem when using pack_padded_sequence, that is, the length of the input mini-batch sequence must be orde
