Creating these visuals is addictive, but getting out of hand. Had to see the difference between torch chunk and unbind, but this visual doesn't need to exist. #TensorViz

Not my best work. Created a visual of torch's transpose op over 3d tensors, but I don't know if the random coloring is instructive or confusing. #TensorViz

TIL `tensor[None]` is just a shorthand for `tensor.unsqueeze( 0)` in torch.

Started a visual explainer for the torch op, `chunk`. The full explainer will have different arg combinations for no. of chunks and dim.

whytorch.org is quietly addictive. It's been fun playing with pytorch tensors in a visual format. Not affiliated with the project. Just a fan.

Fed up with trying to imagine chains of tensor transformations in my head, wrote a library to relieve my pain: github.com/hardik-vala/.... Lets you visualize torch, jax, tf, numpy tensors in notebooks and other python contexts, for understanding and debugging. Enjoy.

is playground mode a new feature in colab? liking it for messing around with a notebook you authored that's also shared

JAX / TPU docs are incomplete. For anyone looking to run Pallas kernels (JAX's kernel lang) on TPUs, make sure you're running Python 3.10+.

Tensor Logic does not seem all that different from torch and tf, and don't see how it solves hallucinations. The unification of symbolic logic, database operations, and tensor transformations was intellectually instructive tho.
