Block diagonal matrix in PyTorch - vectorized
"""A part of the pylabyk library: numpytorch.py at https://github.com/yulkang/pylabyk"""
import torch
def block_diag(m):
"""
Make a block diagonal matrix along dim=-3
EXAMPLE:
block_diag(torch.ones(4,3,2))
should give a 12 x 8 matrix with blocks of 3 x 2 ones.
Prepend batch dimensions if needed.
You can also give a list of matrices.

Global gitignore

There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules directory) as well as files that are generated (and regenerated) as artifacts of a build process.

All other files should be in your own global gitignore file:

  • Create a file called .gitignore in your home directory and add any filepath patterns you want to ignore.
  • Tell git where your global gitignore file is.

Note: The specific name and path you choose aren't important as long as you configure git to find it, as shown below. You could substitute .config/git/ignore for .gitignore in your home directory, if you prefer.

Gross hack to add presenter notes to the HTML export of a keynote presentation.
"""
Export your keynote file to HTML. Pass the keynote file (to extract the
presentation notes) and the extracted HTML directory to this script, and it
will attempt to inject the presenter notes it extracted from the Keynote file
into the HTML.
Only tested on Keynote '09, Chrome 24.0.1312.56
