Keras use only single thread · Issue #1245 · keras-team/keras
I have installed keras on a redhat 6 server, it is really a attractive framework cause it is really easy to build a deep neural network. However, I found my keras use only single thread(or single core). I ran examples given in the source code package, such as "mnist_mlp.py", and used "top" command, found the usage of CPU is 100%, never more than CPU, I have 6 cores, each with four threads, no GPU,
Keras 2.0 release notes
The nb_epoch argument has been renamed epochs everywhere. The methods fit_generator, evaluate_generator and predict_generator now work by drawing a number of batches from a generator (number of training steps), rather than a number of samples. samples_per_epoch was changed to steps_per_epoch in fit_generator. It now refers to the number of batches an epoch is considered as done. nb_val_samples was

A concrete example for using data generator for large datasets such as ImageNet · Issue #1627 · keras-team/keras
I am already aware of some discussions on how to use Keras for very large datasets (>1,000,000 images) such as this and this. However, for my scenario, I can't figure out the appropriate way to use the ImageDataGenerator or write my own dataGenerator. Specifically, I have the following four questions: From this link: when we do datagen.fit(X_sample), do we assume that X_sample is a big enough chun
fit_generator converges slower and tensorboard's OOM problem · Issue #4797 · keras-team/keras
problem 1: i changed my code from fit to fit_generator, however, i found it converged slower than using fit. Using fit it converges at 5th epoch, however, it doesn't converge even at 10th epoch when i change to fit_generator. Moreover, when validation_data also uses fit_generator, the performance becomes much worse. Is my generator function has errors? def batch_iter(x, y, batch_size): """ Generat
Precision, Recall and f1 score for multiclass classification · Issue #6507 · keras-team/keras
Hi! Keras: 2.0.4 I recently spent some time trying to build metrics for multi-class classification outputting a per class precision, recall and f1 score. I want to have a metric that's correctly aggregating the values out of the different batches and gives me a result on the global training process with a per class granularity. The way I understand it is currently working is by calling the functio
