Can I train a neural network model using PyTorch and then use it in Keras, and vice versa?
Are PyTorch and Keras Neural Network models 100% compatible with each other?
The Short answer is Not
Pytorch by facebook and Keras by google are two different frameworks for deep learning.
PyTorch and is known for its dynamic computation graph, while Keras is a neural networks API that runs on top of multiple deep learning frameworks such as TensorFlow
But it is always nice to build all your deep learning models using both (for learning purpose) and eventually you will choose your own framework.
Good Luck
