ImageNet Large Scale Visual Recognition Challenge dataset Updated 2025-07-16
Subset of ImageNet. About 167.62 GB in size according to www.kaggle.com/competitions/imagenet-object-localization-challenge/data.
Contains 1,281,167 images and exactly 1k categories which is why this dataset is also known as ImageNet1k: datascience.stackexchange.com/questions/47458/what-is-the-difference-between-imagenet-and-imagenet1k-how-to-download-it
www.kaggle.com/competitions/imagenet-object-localization-challenge/overview clarifies a bit further how the categories are inter-related according to WordNet relationships:
The 1000 object categories contain both internal nodes and leaf nodes of ImageNet, but do not overlap with each other.
image-net.org/challenges/LSVRC/2012/browse-synsets.php lists all 1k labels with their WordNet IDs.There is a bug on that page however towards the middle:and there is one missing label if we ignore that dummy

Git tips Oh, but there are 2 trees: local and remote Updated 2025-07-16
Oh but there are usually 2 trees: local and remote.
So you also have to learn how to observe and modify and sync with the remote tree!
But basically:to update the remote tree. And then you can use it exactly like any other branch, except you prefix them with the remote (usually
git fetchorigin/*), e.g.:origin/masteris the latest fetch of the remote version ofmasterorigin/my-featureis the latest fetch of the remote version ofmy-feature

Git tips How to visualize the commit tree Updated 2025-07-16
Generate a minimal test repo. You should get in the habit of doing this to test stuff out.
#!/usr/bin/env bash
mkdir git-tips
cd git-tips
git init
for i in 1 2 3 4 5; do
echo $i > f
git add f
git commit -m $i
done
git checkout HEAD~2
git checkout -b my-feature
for i in 6 7; do
echo $i > f
git add f
git commit -m $i
done Git tips Linear history vs branching Updated 2025-07-16
Some people like merges, but they are ugly and stupid. Rebase instead and keep linear history.
Linear history:
5 master

1 first commitBranched history:
7 master

1/ first commitWhich type of tree do you think will be easier to understand and maintain?
????
????????????
You may disconnect now if you still like branched history.
Git tips Why is Git a DAG? Updated 2025-07-16
Git tips It's not a tree, it's actually a DAG Updated 2025-07-16
But not every directed acyclic graph is a tree.
