Tensorflow 2 + Ubuntu 18.04

pip3 install tensorflow-gpu==2.0.0-alpha0

or

pip3 install tensorflow==2.0.0-alpha0

if no nvidia cudo gpu.

jupyter notebook

import tensorflow as tf
print(tf.__version__)

Image annotation

This one is very simple and fast:

https://github.com/Cartucho/OpenLabeling

Would like to have a mode where square is assumed (or some fixed aspect ratio) and the only thing to do is click in the center then scale the square, default would be last scaling.

It would be a good imgui project to make own custom one.

google drive / google photos annotation?

Standalone opengl3 + imgui based annotation https://github.com/lucasw/imgui_test - not a lot of features yet.

image preprocessing

Need a script that will take an image and chop it up into sub images of a given aspect ratio, then resize to desired output resolution/.
Overlap is okay, especially at different resolutions.

May need to manually browse output images and delete those that aren't desired (don't contain the desired content).

Better to do in colab/jupyter, or manually on local disk then upload? Probably the latter.

for i in *jpg; do convert $i -resize 25% ../small/$i; done
