R package rTorch: R Bindings to ’PyTorch’. ’R’ implementation and interface of the Machine Learning platform ’PyTorch’ <https://pytorch.org/> developed in ’Python’. It requires a ’conda’ environment with ’torch’ and ’torchvision’ to provide ’PyTorch’ functions, methods and classes. The key object in ’PyTorch’ is the tensor which is in essence a multidimensional array. These tensors are fairly flexible to perform calculations in CPUs as well as ’GPUs’ to accelerate the process.
