I have managed to implement early stopping into my Keras model, but I am not sure how I can view the loss of the best epoch. The way I have defined the loss score, means that the returned score comes from the final epoch, not the best epoch. Example: So in this example, I would like to see the loss

Are there IEC 61131 / IEC 61499 PLC function blocks that use OPA UA to transport data?
I have a machine learning and advanced control application in Python (TensorFlow + Gekko) that I need to integrate with a Programmable Logic Controller (PLC) that provides the data acquisition and final element control. Can I use a rack-mounted Linux (preferred) or Windows Server as the computational engine, …
ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none) ERROR: No matching distribution found for tensorflow)
I want to install tensorflow to use Keras LSTM I installed Keras, and i import this lines to my code. Error is when runnig the code: Cmd error when i write “pip install tensorflow” : Pip version is 19.3 , python version 3.7 Answer On Windows, you must use Python 3.7.6 (64 bits) (or later version, …
Why is TensorFlow 2 much slower than TensorFlow 1?
It’s been cited by many users as the reason for switching to Pytorch, but I’ve yet to find a justification/explanation for sacrificing the most important practical quality, speed, for eager execution. Below is code benchmarking performance, TF1 vs. TF2 – with TF1 running anywhere from 47% to…
How to load models trained on GPU into CPU (system) memory?
I trained a model on a GPU and now I am trying to evaluate it on CPU (GPU is being used for a different train run). However when I try to load it using: I am getting a CUDA_ERROR_OUT_OF_MEMORY: (I tried also setting compile=True with the same result.) It seems that the model is being loaded into GPU which is
How to generate CNN heatmaps using built-in Keras in TF2.0 (tf.keras)
I used to generate heatmaps for my Convolutional Neural Networks, based on the stand-alone Keras library on top of TensorFlow 1. That worked fine, however, after my switch to TF2.0 and built-in tf.keras implementation (with eager execution) I cannot use my old heatmap generation code any longer. So I re-wrote…
Keras image generator keep giving different number of labels
I am trying to make a simple fine turned Resnet50 model using the Market1501 dataset and keras. So the data set contains images (12000 or so) and 751 labels that I want to use (0-750). I can fit the data into a single go so I have to use a image generator for this. So my base model is like
keras apply threshold for loss function
I am developing a Keras model. My dataset is badly unbalanced, so I want to set a threshold for training and testing. If I’m not mistaken, when doing a backward propagation, neural network checks the predicted values with the original ones and calculate the error and based on the error, set new weights …
Concatenate two models with tensorflow.keras
I’m currently studying neural network models for image analysis, with the MNIST dataset. I first used only the image to build a first model. Then I created a additionnal variable, which is : 0 when the digit is actually between 0 and 4, and 1 when it’s greater or equal than 5. Therefore, I want to…
During creating VAE model throws exception “you should implement a `call` method.”
I want to create VAE(variational autoencoder). During model creating it throws exception. When subclassing the Model class, you should implement a call method. I am using Tensorflow 2.0 Models with names I want to get model. Answer The problem is here: You are passing three arguments to the construction, wher…
