Einsum Is All You Need: NumPy, PyTorch and TensorFlow

In this video I explain how Einstein Summation (einsum) works and why it is amazing, at the end of the video you too will realize that einsum is all you need. It works similar in all libraries with the following function call: torch.einsum, tf.einsum, numpy.einsum (pytorch, tensorflow, numpy).

Video title was recklessly stolen from the following blogpost which I was inspired by (read it!):
