pytorch loss not decreasing

2) Increasing the latent vector size from 292 to 350. This means you won't be getting GPU acceleration. 5. torchvision is designed with all the standard transforms and datasets and is built to be used with PyTorch. I recommend using it. I have implemented a Variational Autoencoder model in Pytorch that is trained on SMILES strings (String representations of molecular structures). NETS: vgg16 As pointed out by Serget Dymchenko, you need to switch the network to eval mode during inference and train mode during train. This mainly affects dropout and batch_norm layers since they behave differently during training and inference. 3. A learning rate of 0.03 is probably a little too high. The main issue is that the outputs of your model are being detached, so they have no connection to your model weights, and therefore as your loss is dependent on output and x I'm relatively new to PyTorch (and deep learning in general) so I would tend to think something is wrong with my model. Epoch 1300 loss: 2891.597194671631 Epoch 700 loss: 2891.483169555664 Here is the pseudo code with explanation, n1_model = Net1(Dimension_in_n1, Dimension_out) # 1-layer nn with sigmoid Any comments are highly appreciated! I read that paper the day it is published. The following is the link to my code. When calculating loss, however, you also take into account how well your model is predicting the correctly predicted images. I am writing a program that make use of the build in LSTM in the Pytorch, however the loss is always around some numbers and does not decrease significantly. My model look like this: There are lots of things that can make training unstable, from data loading to exploding/vanishing gradients and numerical instability.

Why does it matter that a group of January 6 rioters went to Olive Garden for dinner after the riot? However, I am running into an issue with very large MSELoss that does not decrease in training (meaning essentially my network is not training). I've managed to get the model to train but my loss is not decreasing over time. Thanks for contributing an answer to Stack Overflow! zjmtlab (zhang jian) April 4, 2018, 8:45am #1. The following is the result from tensorboardX. I have another issue about the train precision and loss curve. Well occasionally send you account related emails. Personally, i greatly agree with views from "Detnet" and "rethinking imagenet pre-training", however, seems like that much more computation cost and specific tuning skills are needed.

Just as a suggestion from my experience: You first might to get it working without the "Variational", i.e. It will helps you a lot. Yet no good solutions. CHECKPOINTS_EPOCHS: 1 this is a toy code: The loss is not even changing, my model isnt learning anything. There might be a line in there which is causing your gradient to be zero. Also, remember to clear the gradient cache of your parameters (via optimizer.zero_grad()) otherwise your gradients will acculumate from all epochs! There are 252 buckets. Epoch 1900 loss: 2888.922218322754. Why does the sentence uses a question form, but it is put a period in the end? Does the Fog Cloud spell work in conjunction with the Blind Fighting fighting style the way I think it does? It have been discussed in #16. Thanks for the suggestion. @blueardour first, make sure you change the PHASE in .yml file to 'train', then ,actually, i believe it's inappropriate to train a model from scratch, so at least, you should load the pre-train backbone, i just utilize the whole pre-train weight(including backbone and extract and so on..) the author provided, but i set the RESUME_SCOPE in the .yml file to be 'base' only and the resault is almost the same as fine-tune's. https://colab.research.google.com/drive/1LctSm_Emnn5sHpw_Hon8xL5fF4bmKRw5, The following is an equivalent keras model(Same architecture) that is able to train successfully. my loss function aims to minimize the inverse of gap statistic which is used to evaluate the cluster formed from my embeddings. When the loss decreases but accuracy stays the I did not use the CosineAnnealing LR and no such phenomenon ever happened during training. In my previous training, I set 'base' and 'loc' so on all in the trainable_scope, and it does not give a good result. You lose it.

I'm using an SGD optimizer, learning rate of 0.01 and NLL Loss as my loss RESUME_SCOPE: 'base,norm,extras,loc,conf' this is all im doing. SOLUTIONS: Check if you pass the softmax into the CrossEntropy loss. If you do, correct it. For more information, check @rasbt s answer above. Use a smaller learning rate in the optimizer, or add a learning rate scheduler which will decrease the learning rate automatically during training. In my previous training, I set 'base' and 'loc' so on all in the trainable_scope, and it does not give a Have a question about this project?

Epoch 100 loss: 3913.1080932617188 The network does overfit on a very small dataset of 4 samples (giving training loss < 0.01) but on larger data set, the loss seems to plateau around a very large loss. Before my imagenet training finished, i will have to compare sdd performance based on models trained from scratch firstly. After only reload the 'base' and retrain other parameters, I successfully recover the precision. Youll need to calculate your loss value without using the detach() method at all.

What about my 2nd comment? ill get back to you. The problem is that for a very simple test sample case, the loss function is not decreasing. Using the detach function will kill any gradients in your network which is most likely the explanation as to why its not learning. What could cause a VAE(Variational AutoEncoder) to output random noise even after training? Is there a way to make trades similar/identical to a university endowment manager to copy them?
