Keras custom layer not returning weights, unlike normal layer

I am trying to get weights of the layer. It seems to work properly when keras layer is used and the input is connected to it. However, while wrapping it into my custom layer, that does not work anymore. Is that a bug or what am I missing? Edit:…

Select specific features in a Tensorflow 1 layer

I followed this tutorial and used the ipynb notebook from the Github page to generate deepdream images in Google Colaboratory. The tutorial uses the Inception5h network. 12 layers in this model are commonly used for generating images. Each layer…

How to save Tf.contrib model pruning?

I have built a model and I am successfully able to prune it using tf.contrib's model pruning module with default params and sparsity as 90%, but the problem is when I run the model it still takes the same amount of execution time as of the original…

Alternative to arg_scope when using tf.layers

I'm rewriting tf.contrib.slim.nets.inception_v3 using tf.layers. Unfortunately the new tf.layers module does not work with arg_scope, as it does not have the necessary decorators. Is there better mechanism in place that I should use to set default…

Are there alternatives to constant_initializer when assigning weights in tf.contrib.layers

I want to pass weights to tensorflow.contrib.layers.conv2d. The layers have the parameter weights_initializer. When passing the tensor via weights_initializer=tf.constant_initializer(tensor), the tensor is additionally added as a node to the graph,…

Tensorflow convolution layers have strange artefacts

Could anyone explain me what I'm doing wrong that my tensorboard graphs have additional groups when I use tf.layers.conv1d ? For sake of simplicity I've created one tf.name_scope 'conv_block1' that contains: conv1d -> max_pool -> batch_norm, yet my…

Is there a way to add preprocessing functions into a ScaNN model?

I have a ScaNN object and I am capable of loading data and building it. I can also save the model and extract it to my python environment, but I need to give a tf.Tensor variable as the input. If I want to call my model through RestAPI, I need to…

Easy way to set pre-trained weights in tensorflow?

Is there an easy way to set pretrained weights to a tensorflow layer? (w/o keras) In keras it's easy as model.set_weights(...) or layer.set_weights(...) - but I'm breaking my head around this for more than a day in tf, and can't seem to find…
