Others, like Tensorflow or Pytorch give user control over almost every knob during the process of model designing and training. There are cases, when ease-of-use will be more important and others, where we will need full control over our pipeline. Whenever a model will be designed and an experiment performed, one question will still remain - what is the speed of model training and whether it can be trained faster. This aspect is especially important, when we are training big models or have a big amount of data.

Personally, I Kaggle a lot, so more often than not I have to use ensembles of various models. When a lot of models are trained, training time is the key - the quicker they can be trained, the bigger amount of them can be put into my ensemble. That is why I decided to pick three currently post popular frameworks for Deep Learning:.

Keras is a wrapper around Tensorflowso I thought it will be even more interesting to compare speed of theoretically the same models but with different implementations and different training API.

Dataset: Kaggle Dog Breed Identification. In theory, with more parameters in a model, more operations will be needed to perform each gradient update, therefore we expect that with growing number of parameters, training time will also grow.

We can see that InceptionV3 and ResNet50 have the lowest amount of parameters, 22 and 23 millions each. InceptionResNetV2 has around 55 millions of parameters. InceptionResNet V2 takes longest time for epoch, the difference can be seen especially for batch size of 4 left facet. Now, we group frameworks by models to see, which models were fastest using which framework.

In case of Inception models, only TF can be compared to Keras and in both cases Tensorflow is faster. ResNet50 achieves lowest training time when Tensorflow is used. VGG models stand in opposition to that, because both are trained quickest in Pytorch.

Finally, all model runs per framework were averaged to show just a simple plot, which can conclude the whole experiment. In addition to that, every Keras user has probably noticed that first epoch during model training is usually longer, sometimes by a significant amount of time. I wanted to capture this behavior by plotting averaged time of 10 epochs versus time of just the first epoch.

But there is one, which will be felt, when Keras is chosen over those ones. Like everywhere, there must be a trade-off, simplicity comes at a cost. If your data is not very big or you need to focus mostly on rapid experimentation and want a framework that will be elastic and let you perform easy model training, pick Keras.

On the other hand, when you need high-performance models, which can probably be further optimized and speed is of the utmost importance, consider spending some time on developing your Tensorflow or Pytorch pipeline. Number of parameters does in fact increase training time of a model in most cases. VGGs need more time to train than Inception or ResNet with the exception of InceptionResNet in Keras, which needs more time than the rest, altough it has lower number of parameters. Two Deep Learning frameworks gather biggest attention - Tensorflow and Pytorch.

Kaggle is the biggest Data Science community with over 2 million users.
