I want to use one hot to represent group and resource, there are 2 group and 4 resouces in training data: group1 (1, 0) can access resource 1 (1, 0, 0, 0) and resource2 (0, 1, 0, 0) group2 (0 . Each input is of size (64, 1, 28, 28) and the architecture is as follows: self.conv1 = nn.Conv2d(1, 10, kernel_size=5), self.conv2 = nn.Conv2d(10, 20, kernel_size=5), self.fc2 = nn.Linear(50, 10) # (num_features, num_classes), x = F.relu(F.max_pool2d(self.conv1(x), 2)), x = F.relu(F.max_pool2d(self.dropout(self.conv2(x)), 2)). Have you made sure the logsoftmax is being performed along the correct axis? rtkaratekid (rtkaratekid) October 3, 2019, 11:21pm #1. For demonstration, we will use a simple MNIST classifier example that has a couple of bugs: If you run this code, you will find that the loss does not decrease and after the first epoch, the test loop crashes. I have tried different learning rate regimes, but didn't have any luck. The regression loss here is Smooth L1 Loss. Use a more sophisticated model architecture, such as a convolutional neural network (CNN). The resolution is halved with the maxpool layers. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. What is the function of in ? The model is overfitting right from epoch 10, the validation loss is increasing while the training loss is decreasing.. The test loss and test accuracy continue to improve. What is a good way to debug this? Wrapping this functionality into a callback class has the following advantages: Now with the new callback in action, we can open TensorBoard and switch to the Histograms tab to inspect the distribution of the training data: The targets are in the range [0, 9] which is correct because MNIST has 10 digit classes, but the images have values between -130 and -127, thats wrong! 2018-12-01 12:40:18,564 - root - INFO - Epoch: 0, Validation Loss: inf, Validation Regression Loss inf, Validation Classification Loss: 10.0192. It happens for instance when data augmentations are applied in the wrong order or when a normalization step is forgotten. This might involve testing different combinations of loss weights. Reduce learning rate when a metric has stopped improving. By clicking Sign up for GitHub, you agree to our terms of service and If model weights and data are of very different magnitude it can cause no or very low learning progression, and in the extreme case lead to numerical instability. my dataset os imbalanced so i used weightedrandomsampler but didnt worked . If you look at the documentation of CrossEntropyLoss, there is an advice: The input is expected to contain raw, unnormalized scores for each class. Test the network on the test data. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Did Dick Cheney run a death squad that killed Benazir Bhutto? and also creates a meaningful label for each histogram. @qfgaohao Do you have any training logs for MobileNet? PyTorch CNN . I trained HMDB51 dataset for 20 epochs with modelA0_stream_statedict_v3, the result is as follows: @nguyenquibk1996 There are several similar questions, but nobody explained what was happening there. Do you have any idea why this might be? It helps to think about it from a geometric perspective. But the validation loss started increasing while the validation accuracy is not improved. This one here computes the histogram of the input data before it goes into the training step. To learn more, see our tips on writing great answers. I have modified network structure , So I want to be able to locate errors in my code. Any suggestion . In that case I have added my training loop here: for batch_idx, (image, label) in enumerate(train_loader): image, label = image.to(device), label.to(device), loss = F.nll_loss(output, label).to(device), (batch_idx*64) + ((epoch-1)*len(train_loader.dataset))), torch.save(model.state_dict(), 'results/model.pth'), torch.save(optimizer.state_dict(), 'results/optimizer.pth'). If something is not working the way we expect it to work, it is likely a bug in one of these three parts of the code. @nguyenquibk1996 Hi did you solve the problem? . It's unlikely these are problem related to part of the code of this repository. My model doesn't seem to learn anything. On average, the training loss is measured 1/2 an epoch earlier. What is the difference between the following two t-statistics? For the benefit of clarity, the code for the callbacks shown here is very simple and may not work right away with your models. Also, try a small subset of the training data to verify the process is right. Viewed 616 times 1 $\begingroup$ So I am currently trying to . PyTorch Lightning automates all boilerplate/engineering code in a Trainer object and neatly organizes all the actual research code in the LightningModule so we can focus on whats important: Lightning takes care of many engineering patterns that are often a source for errors: training-, validation- and test loop logic, switching the model from train to eval mode and vice versa, moving the data to the right device, checkpointing, logging, and much more. If the process is all right, you should get a overfitted model with 0 loss. Define a loss function. I changed the intendation so it's runnable with ctrl+c. Hi, So I am trying to sanity-check my binary image classification model. If you shift your training loss curve a half epoch to the left, your losses will align a bit better. How do I print the model summary in PyTorch? Non-anthropic, universal units of time for active SETI, How to constrain regression coefficients to be proportional. After fixing the normalization issue, we now also get the expected histogram logged in TensorBoard. I am building a network for image classification using the MNIST dataset. Connect and share knowledge within a single location that is structured and easy to search. It's probably due to the fact that it converges from the first epoch, I had the same problem. I am not doing any validation as of now. 5. It may help to know that I feel like this has happened with other projects of mine in the past. Stack Overflow for Teams is moving to its own domain! I need the softmax layer in the last layer because I want to measure the probabilities. Sign in I first feed that in an char-based Embedding, then padding using pack_padded_sequence, feeding in LSTM , and finally unpacking with pad_packed_sequence. It actually saves us a lot of time that would otherwise be wasted if the error happened after a long training epoch. Edit: It may also be possible that my issue lies outside the model architecture. I was thinking something different. I have some training text data in variable lengths. How do I check if PyTorch is using the GPU? This might just be an issue with how I fundamentally build my networks.

Relu before cross entropy loss throws away information about class scores. Once implemented, it can be easily integrated into new projects by changing two lines of code. @sacmehta Hi, are you able to share your pretrained PyTorch ImageNet weights? You signed in with another tab or window. Parameters optimizer ( Optimizer) - Wrapped optimizer. https://pytorch.org/docs/stable/nn.html#torch.nn.SmoothL1Loss . Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. @relot I just realized I have another advice for you, I think its more important. The fact that Lightning sanity checks our validation loop at the beginning lets us fix the error quickly, since its obvious now that line 65 should read. Training loss not changing at all while training LSTM (PyTorch) Training loss not changing at all while training LSTM (PyTorch) No Active Events. Try training your network by removing last relu from conv5 and keeping lr=0.01 and momentum=0.9. Then I tried to train hmdb51 without pretrained, the evaluation accuracy is as follows: I think the dataset is primary cause, and the data processing method(one clip or multiple clips sampled from one video) is second cause. Well occasionally send you account related emails. If you look at the documentation of CrossEntropyLoss, there is an advice: The input is expected to contain raw, unnormalized scores for each Thanks for contributing an answer to Stack Overflow! With the learningrate of 0.01 it's stuck at 2.303. So I am currently trying to implement an LSTM on Pytorch, but for some reason the loss is not decreasing. If the letter V occurs in a few native words, why isn't it included in the Irish Alphabet? If I trained Movinet not using pretrained Kinetics with HMDB51 in the notebook sample and my own dataset (i did not save a log of the training), both losses had not decreased. neural-networks Hi, I am trying to reproduce your results, but validation regression loss is infinte. How many characters/pages could WordStar hold on a typical CP/M machine? If loss decreases, means its a hyper parameter problem with SGD. The notebook functions correctly, also I use the networks daily. Learn on the go with our new app. 2018-12-01 12:38:16,778 - root - INFO - Epoch: 0, Step: 100, Average Loss: 12.1986, Average Regression Loss 2.7535, Average Classification Loss: 9.4451 Whats wrong? What does puncturing in cryptography mean. Train the model on the training data. Funny we noticed the other problem at the same time. Find centralized, trusted content and collaborate around the technologies you use most. Love podcasts or audiobooks? The loss I have written in the post was created with adam. This is not a good solution, because it pollutes the code unnecessarily, fills the terminal and overall takes too much time to repeat it later on should we need to. Say you have some complex surface with countless peaks and valleys. Pytorch identifying batch size as number of channels in Conv2d layer. Best way to get consistent results when baking a purposely underbaked mud cake. Better: Write a Callback class that does it for us! 2022 Moderator Election Q&A Question Collection. I changed the learningrate but this doesn't seem to be the problem. For your own datasets you would have to compute it yourself. Here is the rest of the code. A small contrived . It seems that if validation loss increase, accuracy should decrease. Below is the implementation for n = 3: And here is the same in a Lightning Callback: Applying this test to the LitClassifer immediately reveals that it is mixing data. Loss is nan while validation accuracy stays consistent in Loss doesn't decrease substantially using Flux.jl Loss of all automation data and audiofx of the dmd when Loss of lines when converting from SketchUp to .GLB. Press question mark to learn the rest of the keyboard shortcuts. Not the answer you're looking for?

Sign up for a free GitHub account to open an issue and contact its maintainers and the community. class. Batchsize is 4 and image resolution is 32*32 so inputsize is 4,32,32,3 : I am using PyTorch weights and not Caffe weights. Why did it happened? Surprisingly, much of this can be automated. Symptoms: validation loss is consistently lower than the training loss, the gap between them remains more or less the same size and training loss has fluctuations. For example, in PyTorch I would mix up the NLLLoss and CrossEntropyLoss as the former requires a softmax input and the latter doesn't. 20. Instead of scaling within range (-1,1), I choose (0,1), this right there reduced my validation loss by the magnitude of one order When I trained Movinet with my own dataset. Code, training, and validation graphs are below. Make sure the feature map size used for prior generation is the same as feature maps from CNN used for SSD. This can be diagnosed from a plot where the training loss is lower than the validation loss, and the validation loss has a trend that suggests further improvements are possible. to your account. Why is the loss function not decreasing in PyTorch? In this post I will show you how you can. Adjust loss weights. How to help a successful high schooler who is failing in college? https://pytorch.org/docs/stable/nn.html#torch.nn.SmoothL1Loss, Got nan Regression loss and inf Classification loss on pytorch 1.5. Before we debug this code, we will organize it into the Lightning format. I checked and found while I was using LSTM: I simplified the model - instead of 20 layers, I opted for 8 layers. Loss is not decreasing. PyTorch Lightning takes care of that part by removing the boilerplate code surrounding training loop engineering, checkpoint saving, logging etc. Sign in PyTorch Lightning has logging to TensorBoard built in. ( see the below image ) If I trained Movinet not using pretrained Kinetics with HMDB51 in the notebook sample and my own dataset (i did not save a log of the training), both losses had not decreased. Well, I rewrote most of the SSD code from here: You can find my implementation here and see if it helps: Thanks for your reply, could you tell me what caused the inf loss? I've managed to get the model to train but my loss is not decreasing over time. Can be extended by subclassing or be combined with other callbacks. What is left is the actual research code: the model, the optimization and the data loading. Some help would really be appreciated. If you noticed, Lightning runs two validation steps before the training begins. Because I used the same function for my own dataset and got the same problem. Share Follow Each of the last filters should predict it's corresponding class. Anyone an idea why this might happen? One of my nets is a good old fashioned autoencoder I use for anomaly detection . Problem is that my loss is doesn't decrease and is stuck around the same point. Now knowing what we are looking for, we quickly find a mistake in the forward method. I reproduced your example (tweaking a bit the code, there are typos here and there), and I don't even see a change in the loss: it is stuck at 2.303. Does it make sense to say that if someone was hired for an academic position, that means they were the "best"? Model compelxity: Check if the model is too complex. Why don't we consider drain-bulk voltage instead of source-bulk voltage in body effect? Hi, I am new to deeplearning and pytorch, I write a very simple demo, but the loss can't decreasing when training. 2018-12-01 12:39:10,253 - root - INFO - Epoch: 0, Step: 400, Average Loss: 6.8956, Average Regression Loss 2.1017, Average Classification Loss: 4.7939 By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy.

The curve of loss are shown in the following figure: It also seems that the validation loss will keep going up if I train the model for more epochs. 2018-12-01 12:38:51,741 - root - INFO - Epoch: 0, Step: 300, Average Loss: 7.1205, Average Regression Loss 2.2209, Average Classification Loss: 4.8996 Try training your network by removing last relu from conv5 and keeping lr=0.01 and momentum=0.9. If your loss is composed of several smaller loss functions, make sure their magnitude relative to each is correct. 4. At this moment, I have a Variable of BATCH_SIZE*PAD_LENGTH*EMBEDDING_LEN and another Variable of the real length of each. Increase the size of the training data set. When taken at dim=1, the loss hovers around 4.15x, Use Adam optim. The training loss decreased but the validation loss increased from the first epoch. Would be great if you can provide some insights into this issue? if not, its a problem with code or data. Error in training PyTorch classifier from the 60 minute blitz in GPU, Output of the model depends on the shape of the weights tensor. Every Deep Learning project is different. save valuable debugging time with PyTorch Lightning. Something is still wrong. @sacmehta I have the same issues with you, not only validation loss, sometimes the training loss occurs inf of Average Loss, Average Regression Loss, but the classification loss continues to decline how do you solve it? The text was updated successfully, but these errors were encountered: Hi @sacmehta , are you using your own dataset? So far I've found pytorch to be different but MUCH more intuitive. When these functions are applied on the wrong dimensions or in the wrong order, we usually get a shape mismatch error, but this is not always the case! When I train I am getting a constant loss value and no change. When the validation loss is not decreasing, that means the model might be overfitting to the training data. I am training it to overfit on 20 samples, now theoretically training loss should decrease and validation loss should increase. Validation Loss did not decrease in the HMDB51 notebook? But I want to use a different model. The idea is simple: If we change the n-th input sample, it should only have an effect on the n-th output. Any idea what might go wrong? No matter how much experience you bring with you, there will always be new challenges and unexpected behavior you will struggle with. Regex: Delete all lines before STRING, except one particular line. I met the same problem in my own dataset. Hi did you solve the problem? The skill- and mindset that you bring to the project will determine how quickly you discover and adapt to the obstacles that stand in the way of success. After a day of racking my brain trying to figure this out. This is not a bug, its a feature! It is important that you always check the range of the input data. Pytorch LSTM not training. Reddit and its partners use cookies and similar technologies to provide you with a better experience. If these conditions are met, the model passes the test. There could be many reasons for this: wrong optimizer, poorly chosen learning rate or learning rate schedule, bug in the loss function, problem with the data etc. I don't think it can converges from the first epoch with many datasets. I am trying to reproduce your results, but validation regression loss is infinte. Relu before cross entropy loss throws away information about class scores. Because the model should not be learning anything but both my train & val loss are decreasing here Validation accuracy is also following a non-random pattern, Is my assertion for performance . Reason #3: Your validation set may be easier than your training set or . Its been a while. Then I tried to train hmdb51 without pretrained, the evaluation accuracy is as follows: Did I miss any key points during finetuning or could you give any clues about this? I changed the optimizer to, and now the loss is decreasing as expected (way faster than the tutorial with the same amount of parameters). Here is my network: class MyNN(nn.Module): def __init__(self, input_size=3, seq_len=107, . In fact, I have already done it for you in this repository. Organizing it is easy in the beginning, but as the project grows in complexity, more and more time is spent in debugging and sanity checking. find out why your training loss does not decrease. It is separate from your research code; there is no need to modify your LightningModule! Any comments are highly appreciated! lr= [0.1,0.001,0.0001,0.007,0.0009,0.00001] , weight_decay=0.1 . Now I use filtersize 2 and no padding to get a resolution of 1*1. Asking for help, clarification, or responding to other answers. Models often benefit from reducing the learning rate by a factor of 2-10 once learning stagnates. Reason #2: Training loss is measured during each epoch while validation loss is measured after each epoch. rev2022.11.3.43005. I am able to fix the above issue, but now I am getting another issue. Making statements based on opinion; back them up with references or personal experience. I trained your HMDB51 notebook in 10 epochs but the validation loss did not decrease? We should be able to find out by printing the min- and max values. P.S. Would be great if you can provide s. You can optionally divide by its length in order to normalize the loss, so the scale will be the same if you increase the validation set one day. I had this issue - while training loss was decreasing, the validation loss was not decreasing. If you've done the previous step of this tutorial, you've handled this already. If other outputs i n also change, the model mixes data and thats not good! A common source of error are operations that manipulate the shape of tensors, e.g., permute, reshape, view, flatten, etc., or operations that are applied to a single dimension, e.g., softmax. I dont remember it. There are a few ways to reduce validation loss: 1. loss: 2.270 loss: 2.260 loss: 2.253 loss: 2.250 loss: 2.232 while in the tutorial the loss decreases way faster. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. But wait! Dropout penalizes model variance by randomly freezing neurons in a layer during model training. It might be helpful if you check out some input data and intermediate values. 2018-12-01 12:39:45,364 - root - INFO - Epoch: 0, Step: 600, Average Loss: 6.5128, Average Regression Loss 1.8923, Average Classification Loss: 4.6204 The shape of the output is now (4,1,1,10). The model verification is a bit more sophisticated and also works with multiple in- and outputs. The log says the regression loss is Inf. This is identical to the code in the tutorial but I have to reshape the output so it fits. I will run your notebook with HMDB51 for 10 epochs and show to you a log of the training. Let's say that we observe that the validation loss has not decreased for 5 consecutive epochs. Extending TorchVisions Transforms to Object Detection Getting Started with Facial Keypoint Detection using Deep is it possible to use several different pytorch models on Press J to jump to the feed. In addition, there is a ModuleDataMonitor which can even log the inputs and outputs of each layer in the network. Is this the case in our example? How to distinguish it-cleft and extraposition? These nasty bugs are hard to track down. I am reimplementing the pytorch tutorial of the Pytorch cifar10 tutorial. Add dropout, reduce number of layers or number of neurons in each layer. Hi, I am taking the output from my final convolutional transpose layer into a softmax layer and then trying to measure the mse loss with my target. In this blog post, we implemented two callbacks that help us 1) monitor the data that goes into the model; and 2) verify that the layers in our network do not mix data across the batch dimension. 2018-12-01 12:39:27,837 - root - INFO - Epoch: 0, Step: 500, Average Loss: 6.6482, Average Regression Loss 1.9754, Average Classification Loss: 4.6728 THIS was the reason my loss was not decreasing. Pytorch tutorial loss is not decreasing as expected, Making location easier for developers with new data primitives, Stop requiring only one assertion per unit test: Multiple assertions are fine, Mobile app infrastructure being decommissioned. The problem is that for a very simple test sample case, the loss function is not decreasing. But the most commonly used method is when the validation loss does not improve for a few epochs. After the normalization is applied, the pixels will have mean 0 and standard deviation 1, just like the weights of the classifier. When you train Movinet with your dataset, the validation loss decreases or not? Ask Question Asked 2 years ago. Plz also reference the implementation is PyTorch.
