What Are The Key Differences Between TensorFlow And PyTorch ?
Let us now understand some key differences between Tensorflow & PyTorch based on some important parameters.
Research Paper Implementations
It’s evident that PyTorch is the preferred choice of the majority of researchers. Data from Paperswithcode shows that in June 2023 95% of all published papers utilize PyTorch framework compared to about 5% for TensorFlow.
Accuracy & Training Time
Let’s take a closer look at the accuracy and training time comparison between TensorFlow and PyTorch. The graphs illustrating accuracy reveal a striking similarity in the performance of both frameworks. As the models undergo training, their accuracy steadily climbs, a sign that they’re learning from the data they’re being exposed to.
Validation accuracy, a vital measure of how well a model learns during training, sheds light on the effectiveness of the learning process. Impressively, both TensorFlow and PyTorch models showcase an average validation accuracy of around 78% after 20 training epochs. This striking resemblance underscores the fact that both frameworks excel in implementing neural networks accurately.
When it comes to accuracy, it’s clear that TensorFlow and PyTorch are on par, consistently producing comparable results. This further reaffirms that, armed with the same model and dataset, both frameworks possess the capability to yield identical outcomes, highlighting their robustness and reliability.
In the quest for optimal performance, both TensorFlow and PyTorch stand strong, promising accurate and consistent results in a side-by-side comparison.
Performance Comparison
The provided table offers insights into the training speed of the two models utilizing 32-bit floating-point precision. The benchmark quantifies throughput in different units – images per second for models like AlexNet, VGG-19, ResNet-50, and MobileNet, tokens per second for the GNMTv2 model, and samples per second for the NCF model.
Notably, the benchmark data indicates that PyTorch outperforms TensorFlow in terms of training speed. This distinction can be attributed to a crucial factor: both frameworks leverage the same version of cuDNN and cuBLAS libraries, offloading a substantial portion of computations to these libraries. This strategic utilization of optimized libraries contributes significantly to the superior training speed exhibited by PyTorch.
The data showcased in the benchmark reinforces PyTorch’s efficacy in rapidly training models, making it a compelling choice for practitioners seeking efficient and accelerated training processes
