Latest commit 6d5cdd7 Feb 17, History. Raw Blame. This network is used to predict the next frame of an artificially generated movie which contains moving squares.

The squares are of shape 1x1 or 2x2 pixels, which move linearly over time. For convenience we first create movies with bigger width and height 80x80 and at the end we select a 40x40 window.

The idea is that if during inference, the value of the pixel is not exactly one, we need to train the network to be robust and still consider it as a pixel belonging to a square. You signed in with another tab or window. Reload to refresh your session.

We create a layer which take as input movies of shape. Artificial data generation:. Generate movies with 3 to 7 moving squares inside.

The squares are of shape 1x1 or 2x2 pixels.So what do you think guys the problem is? Hy guys, please make sure your current tensorflow support tf. Data API for Keras. What is your current tf.

It must be greater than 1. Great snippet. Very precise and complete. Thank you. It worked, but the fit function doc still show fit x, y, Same error as was84san but I'm on:.

Update : The issue seems to come from using keras as a module instead of the tensorflow. Using tensorflow.

Model works as expected. I have userd tensorflow. And my versions of keras and tensorflow are 2. Hello, sorry if this is not directly related to this code sample. This is the most related post that I could find. I am trying to make tf. The code looks like that:.

Full shape received: [None, 1, 3].

The installation instructions can be found here. Then I fit the model with data of shape 52, 15,1. As I have an image per timestep, I am a bit stumped as to how I can format my data so it fits this input requirement. I tried adding a 5th dimension, with value 1, 1 samplemaking the input array of shape 1, 52, 15,1. Also added an extra dimension to the labels array. I thought that the layers figured out the dimensions in between them - and we are only supposed to be careful with the dimensions at the beginning - by the time we get to the last layer it should be all worked out.

It depends on the problem you are trying to solve. Your target y should be changed accordingly. Try to see if your problem is a many-to-one or many-to-many.

By your model definition seem that you are doing classification many-to-one. Which means, many time steps pointing to one class. By definition you need: samples,time, rows, cols, channels X: 1, 52, 15,1 means that you have only one sample that is a sequence of 52 images.

The batch size is always omitted since only the shape of each sample is specified. Here's the shape: """ inputs. In the code version, the connection arrows are replaced by the call operation. A "graph of layers" is an intuitive mental image for a deep learning model, and the functional API is a way to create models that closely mirrors this.

You can later recreate the same model from this file, even if the code that built the model is no longer available. That means that a single graph of layers can be used to generate multiple models. By calling a model you aren't just reusing the architecture of the model, you're also reusing its weights. Dense 1 inputs return keras. For example, if you're building a system for ranking customer issue tickets by priority and routing them to the correct department, then the model will have three inputs: - the title of the ticket text input- the text body of the ticket text inputand - any tags added by the user categorical input This model will have two outputs: - the priority score between 0 and 1 scalar sigmoid outputand - the department that should handle the ticket softmax output over the set of departments.

You can even assign different weights to each loss -- to modulate their contribution to the total training loss. A common use case for this is residual connections. Dropout 0.Compat aliases for migration See Migration guide for more details. It is similar to an LSTM layer, but the input transformations and recurrent transformations are both convolutional.

Specifying any stride value! The ordering of the dimensions in the inputs. By default hyperbolic tangent activation function is applied tanh x.

If True, add 1 to the bias of the forget gate at initialization. This is recommended in Jozefowicz et al. Whether to return the last output in the output sequence, or the full sequence. If True, process the input sequence backwards. If True, the last state for each sample at index i in a batch will be used as initial state for the sample of index i in the following batch. Fraction of the units to drop for the linear transformation of the inputs.

Fraction of the units to drop for the linear transformation of the recurrent state. ValueError in case of invalid constructor arguments. View source. Args: states: Numpy arrays that contains the value for the initial state, which will be feed to cell at the first time step.

When the value is None, zero filled numpy array will be created based on the cell state size. ValueError When the input numpy array is not compatible with the RNN layer state, either size wise or dtype wise.
