QUESTION
Say I have an MLP that looks like:
...ANSWER
Answered 2021-Jun-15 at 02:43In your problem you are trying to use Sequential API to create the Model. There are Limitations to Sequential API, you can just create a layer by layer model. It can't handle multiple inputs/outputs. It can't be used for Branching also.
Below is the text from Keras official website: https://keras.io/guides/functional_api/
The functional API makes it easy to manipulate multiple inputs and outputs. This cannot be handled with the Sequential API.
Also this stack link will be useful for you: Keras' Sequential vs Functional API for Multi-Task Learning Neural Network
Now you can create a Model using Functional API or Model Sub Classing.
In case of functional API Your Model will be
Assuming Output_1 is classification with 17 classes Output_2 is calssification with 2 classes and Output_3 is regression
QUESTION
I have a NET like (exemple from here)
...ANSWER
Answered 2021-Jun-07 at 14:26The most naive way to do it would be to instantiate both models, sum the two predictions and compute the loss with it. This will backpropagate through both models:
QUESTION
If I need to freeze the output layer of this model which is doing the classification as I don't need it.
...ANSWER
Answered 2021-Jun-11 at 15:33You are confusing a few things here (I think)
Freezing layersYou freeze the layer if you don't want them to be trained (and don't want them to be part of the graph also).
Usually we freeze part of the network creating features, in your case it would be everything up to self.head
.
After that, we usually only train bottleneck (self.head
in this case) to fine-tune it for the task at hand.
In case of your model it would be:
QUESTION
İ am working on transfer learning for multiclass classification of image datasets that consists of 12 classes. As a result, İ am using VGG19. However, the accuracy of the model is as much lower than the expectation. İn addition train and valid accuracy do not increase. Besides that İ ma trying to decrease the batch size which is still 383
My code:
...ANSWER
Answered 2021-Jun-10 at 15:05383 on the log is not the batch size. It's the number of steps which is data_size / batch_size
.
The problem that training does not work properly is probably because of very low or high learning rate. Try adjusting the learning rate.
QUESTION
I have created and trained one very simple network in pytorch as shown below:

Answered 2021-Jun-11 at 09:55I suspect this is due to you not having set the model to inference mode with
QUESTION
İ am working on transfer learning for multiclass classification of image datasets that consists of 12 classes. As a result, İ am using VGG19. However, I am facing an error i.e. Facing ValueError: Shapes (None, None) and (None, 256, 256, 12) are incompatible. Moreover, İ have flaten layers too
My code:
...ANSWER
Answered 2021-Jun-10 at 10:22As @Frightera mentioned in the comments, you have defined Sequential 2 times.
And I have to add that you DON'T have to complicate the model from the first time, try to run a simple one because VGG19 will do all the work for you.
Adding many Dense layers after the VGG19 doesn't mean you get better scores, as the number of layers is a hyperparameter.
Also try to fix a small learning rate at the beginning as 0.1, 0.05, or 0.01.
QUESTION
The model.eval()
method modifies certain modules (layers) which are required to behave differently during training and inference. Some examples are listed in the docs:
This has [an] effect only on certain modules. See documentations of particular modules for details of their behaviors in training/evaluation mode, if they are affected, e.g.
Dropout
,BatchNorm
, etc.
Is there an exhaustive list of which modules are affected?
...ANSWER
Answered 2021-Mar-13 at 14:22Searching site:https://pytorch.org/docs/stable/generated/torch.nn. "during evaluation" on google, it would appear the following modules are affected:
Base class Modules Criteria_InstanceNorm
InstanceNorm1dInstanceNorm2d
InstanceNorm3d
track_running_stats=True
_BatchNorm
BatchNorm1d BatchNorm2d
BatchNorm3d
SyncBatchNorm
_DropoutNd

QUESTION
I am trying to implement GoogleNet inception network to classify images for classification project that I am working on, I used the same code before but with AlexNet network and the training was fine, but once I changed the network to GoogleNet architecture the code kept throwing the following error:
...ANSWER
Answered 2021-Jun-08 at 08:22GoogleNet is different than Alexnet, in GoogleNet your model has 3 outputs, 1 main and 2 auxiliary outputs connected in intermediate layers during training:

I am working on a project for pneumonia detection. I have looked over kaggle for notebooks on the same. there was a user who stacked two pretrained model densenet169 and mobilenet. I copies whole kaggle notebook from the user where he didn't get any error, but when I ran it in google colab I get this error in this part:

Here is a fixed version of your code
QUESTION
I have modified VGG16 in pytorch to insert things like BN and dropout within the feature extractor. By chance I now noticed something strange when I changed the definition of the forward method from:
...ANSWER
Answered 2021-Jun-07 at 14:13I can't run your code, but I believe the issue is because linear layers expect 2d data input (as it is really a matrix multiplication), while you provide 4d input (with dims 2 and 3 of size 1).
