Reading Tensorflow Dataset changes bahaviour of `take()` and `skip()`
I am trying to inspect the labels inside my tensorflow dataset. However, the values of the labels change to something unexpected after using take() and skip(), depending on whether I inspect the data or not. (It looks like within the labels some ones changed to zeros.) I do not see any way that my inspection …
How to remove first N layers from a Keras Model?
I would like to remove the first N layers from the pretrained Keras model. For example, an EfficientNetB0, whose first 3 layers are responsible only for preprocessing: As M.Innat mentioned, the first layer is an Input Layer, which should be either spared or re-attached. I would like to remove those layers, bu…
Getting the number of words from tf.Tokenizer after fitting
I initially tried making an RNN that can predict Shakespeare text, and I did it successfully using character level-encoding. But when I switched to word level encoding, I ran into a multitude of issues. Specifically, I am having a hard time getting the total number of characters (I was told it was just datase…
How is the Tensorflow documentation created? (Especially the Jupyter notebook parts)
Here is an example page of the Tensorflow documentation: https://www.tensorflow.org/probability/examples/A_Tour_of_TensorFlow_Probability Here is the source of that page: Link How is the Jupyter notebook converted into the HTML website? I think the collapsible code blocks and the table of contents on the righ…
how do I fit a time-series multi head model?
I try to create a model by concatenating 2 models together. The models I want to use, shall handle time series, and I’m experimenting with Conv1D layers. As these have an 3D input shape batch_shape + (steps, input_dim) and the Keras TimeseriesGenerator is providing such, I’m happy being able to ma…
VGG16 Network for Multiple Inputs Images
I am trying to use the VGG16 network for multiple input images. Training this model using a simple CNN with 2 inputs gave me an acc. of about 50 %, which is why I wanted to try it using an established model like VGG16. Here is what I have tried out: I get this error while calling the Model function.
Getting attribute error when using AUTOTUNE in Tensorflow?
I am using AUTOTUNE for audio processing. But i am getting attribute error which said “module ‘tensorflow._api.v2.data’ has no attribute ‘AUTOTUNE’”. Tensorflow version is 2.3.0. How to solve this? Answer According to the TensorFlow 2.3 documentation, AUTOTUNE lies under the tens…
tf.train.Checkpoint is restoring or not?
I am running tensorflow 2.4 on colab. I tried to save the model using tf.train.Checkpoint() since it includes model subclassing, but after restoration I saw It didn’t restored any weights of my model. Here are few snippets: When I later restored it I didn’t get any gru weights: I also tried checkp…
Reshaping MNIST for ResNet50
I am trying to train the mnist dataset on ResNet50 using the Keras library. The shape of mnist is (28, 28, 1) however resnet50 required the shape to be (32, 32, 3) How can I convert the mnist dataset to the required shape? Answer You need to resize the MNIST data set. Note that minimum size actually depends o…
