PyTorch vs baikal: What are the differences?
Developers describe PyTorch as "A deep learning framework that puts Python first". PyTorch is not a Python binding into a monolothic C++ framework. It is built to be deeply integrated into Python. You can use it naturally like you would use numpy / scipy / scikit-learn etc. On the other hand, baikal is detailed as "A graph-based functional API for building complex scikit-learn pipelines". It is a graph-based, functional API for building complex machine learning pipelines of objects that implement the scikit-learn API. It is mostly inspired on the excellent Keras API for Deep Learning, and borrows a few concepts from the TensorFlow framework and the (perhaps lesser known) graphkit package. It aims to provide an API that allows to build complex, non-linear machine learning pipelines.
PyTorch and baikal can be primarily classified as "Machine Learning" tools.
PyTorch and baikal are both open source tools. PyTorch with 37.3K GitHub stars and 9.47K forks on GitHub appears to be more popular than baikal with 553 GitHub stars and 23 GitHub forks.
