--no_gui auto      No GUI mode. (headless mode) Acceleration for full_resolution mode, but unstable on thumbnail mode.
                   Default: "auto" - false if full=false, true if full=true
                   (can be used for docker linux system)

                   Every thread will randomly choose one from the list.

Full Resolution Mode

You can download full resolution image of JPG, GIF, PNG files by specifying --full true

Data Imbalance Detection

Detects data imbalance based on number of files.

When crawling ends, the message show you what directory has under 50% of average files.

I recommend you to remove those directories and re-download.

Remote crawling through SSH on your server

sudo apt-get install xvfb <- This is virtual display

sudo apt-get install screen <- This will allow you to close SSH terminal while running.

screen -S s1

Xvfb :99 -ac & DISPLAY=:99 python3 main.py

Customize

You can make your own crawler by changing collect_links.py
