Tools to download phoenix replays from tenhou.net.
For example, these logs can be useful for machine learning.
This repo contains two main scripts:
- Download and store log IDs. It can both obtain game IDs from year archive (e.g., http://tenhou.net/sc/raw/scraw2009.zip) or from latest phoenix games page (http://tenhou.net/sc/raw/list.cgi).
- Download logs content for already collected log IDs.
Just install requirements with command pip install -r requirements.txt
For example, we want to download game IDs for the 2009 year (keep in mind that phoenix games started to appear only from the 2009 year).
Input command:
python main.py -a id -y 2009
If the script is doing download really slow, you can download the archive with wget or your browser and put it in the temp folder.
Example: Download http://tenhou.net/sc/raw/scraw2009.zip and put it to the temp/scraw2009.zip. In that case, the script will skip the downloading step.
Output:
Set up new database /path/to/db/2009.db
Downloading... scraw2009.zip

To download games from 1 January (current year) until (current day - 7 days) specify -s flag:
python main.py -a id -s -p db/2021.db
To download just log IDs from the latest 7 days:
python main.py -a id -p db/2021.db
You can add this command to the cron (for example to run each one hour) and it will add new log IDs to the DB.
You can download hanchans where yakuman was collected for past months with this command:
python download_yakuman_game_ids.py -y 2020 -m 11 -p /path/to/db.db
To download log content for already downloaded IDs use this command:
python main.py -a content -y 2009 -l 50 -t 3
Where is -l is how many items to download and -t is the number of threads to use.
It will create N threads and parallel downloads.
You can choose that -l and -t numbers to download logs that will take ~one minute and add this command to a cron job.
I used -l 180 -t 5 for my downloads.
Sometimes log content can't be downloaded because of different reasons (e.g., internet connection issues, tenhou server responsibility).
And sometimes tenhou returns for log A content from log B and it causes the same log content for different log IDs in our DB.
For example for the 2009 year (with total 80156 logs) I had ~1500 not downloaded logs and ~800 logs with double content. So, ~2.9% of records had issues at the end of the downloading process.
To fix these issues run this command:
python debug.py -y 2009
It will detect and add all broken records to the download queue again and you can redownload them as usual.
