Error while importing VGG16 h5 file ValueError: No model found in config file

I tried to import vgg16 which I downloaded from google storage import keras import cv2 from keras.models import Sequential, load_model But I got th

How should the output of my embedding layer look? Keras to PyTorch

I am in the process of translating a Keras implementation to a PyTorch one. After the full conversion my model was not converging fast enough, although the loss

use part of Keras Sequential model to predict

In the following code I have defined a Sequential model, that contains two parts conv_encoder and conv_decoder. After training the model I want to use conv_enco

In keras/ tensorflow, Is there a way to add a preprocessing layer to the output, similar to TargetTransformRegressor in sklearn?

I want to use keras to build a neural network regression model from X_train -> Y_train. In this example, however, I need to perform a preprocessing transform

No dimension mismatch for Keras sequential model?

I created a sequential neural network with Keras that has an input of 4 and an output of 8. I realize what I did was incorrect but I'm not sure as to why the co

How to do atrous convolution in tensorflow 2 (tf.keras)

I am trying to convert some code from tensorflow 1.x to tensorflow 2.x. It's been going well so far, but I'm stuck on atrous convolution. Unlike other layers, t

Input 0 of layer "conv2d_transpose_4" is incompatible with the layer: expected ndim=4, found ndim=2. Full shape received: (None, 100)

I am trying to develop a GAN, I have created the generator and the discriminator and now I am trying to train it. I am using the Mnist dataset but I plan to use

How to fix LSTM Layer Error - Image Classification

Currently I'm working on an image classification issue and created the following code based on a tutorial online - Image Classification using Keras. The code w

Using datagen.flow_from_directory with image segmination and number of classes

I used "flow_from_directory" but my "lose" is not decreasing. I notice When I run "fit_generator". Its says there is 1 classes, even though my mask have 3 class

Keras: difference of InputLayer and Input

I made a model using Keras with Tensorflow. I use Inputlayer with these lines of code: img1 = tf.placeholder(tf.float32, shape=(None, img_width, img_heigh, i

Keras LSTM fit underfitting

I have time series training data of about 5000 numbers. For each 100 numbers, I am trying to predict the 101st. At the end of the series, I would put in the pre

assertion failed: [Condition x == y did not hold element-wise:]

I have built a BiLSTM model with an attention layer for sentence classification task but I am getting an error that my assertion has failed due to mismatch in n

Incremental learning in keras

I am looking for a keras equivalent of scikit-learn's partial_fit : https://scikit-learn.org/0.15/modules/scaling_strategies.html#incremental-learning for incre

ValueError: logits and labels must have the same shape ((None, 328, 328, 3) vs (None, 1)) with autoencoder

I am trying to build an autoencoder with the following code import matplotlib.pyplot as plt import numpy as np import pandas as pd import seaborn as sns import

Input 0 of layer sequential is incompatible with the layer expected ndim=3, found ndim=2. Full shape received: [None, 1]

I am working with keras for text classification. After pre-processing and vectorization my train and validation data details is like bellow: print(X_train.shape

TFA BeamSearchDecoder Clarification Request

If the question seems to dumb, it is because I am new to TensorFlow. I was implementing a toy endocer-decoder problem using TensorFlow 2’s TFA seq2seq imp

Keras - no good way to stop and resume training?

After a lot of research, it seems like there is no good way to properly stop and resume training using a Tensorflow 2 / Keras model. This is true whether you ar

Keras: the difference between LSTM dropout and LSTM recurrent dropout

From the Keras documentation: dropout: Float between 0 and 1. Fraction of the units to drop for the linear transformation of the inputs. recurrent_dropout: F

What does keras 'accuracy' mean in seq2seq model?

I'm trying to build a seq2seq model to predict sequence. The most basic model was built, but I'm having trouble with understanding what 'metric=['accuracy']' me
