Here is a bash script I have written which automates submissions to daily tournaments from home machines, without using Compute or web hooks or any other complications. If you want to learn to write similar scripts yourself, you may like to buy my e-book Bash for Fun
Edit:
-
Now an updated version that executes Tuesdays till Saturdays inclusive (can be changed).
-
Simplified version that uses sleep instead of rewriting crontab.
It is assumed that your script does all else that is necessary: that is check for new validations and live data, download them when necessary, do the processing and send the predictions to the server.
#!/bin/bash
# Sets up cron checks for new numerai rounds TUE-FRI, from 13:01 UTC.
# Local timezone is taken care of, as long as it is not sub-hourly.
# Activate only once, verify with crontab -l, deactivate with crontab -r
# Make sure that your computer and internet connection are on at the target time
# days of the week to be checking for new tournaments - no spaces!
FIRSTDAY=Tue
LASTDAY=Sat
# hours in UTC to be checking from
HRS=13
# at MINS minutes intervals after the initial attempt at $HRS:01
MINS=5
# name of bash script here that downloads live data, generates predictions and uploads them
PREDICT=numbatch
# full path/name of fully installed numerapi CLI (python) script
NAPI=/home/l/.local/bin/numerapi
# name of log file here
LOG=cronlog

# crontab expects by default local time, so convert from UTC
LHRS=`date -d "$HRS UTC" +%H`
DAYS=`date -d "$HRS next $FIRSTDAY UTC" +%w`-`date -d "$HRS next $LASTDAY UTC" +%w`
# no argument given means first time manual startup to initiate crontab

[ $1 ] || {
printf "1 $LHRS * * $DAYS $SCRIPT r >> $PD/$LOG\n" | crontab - && {
printf "$0: `date` crontab initiated:\n`crontab -l`\n" | tee -a $PD/$LOG

I have now also multithreaded my Rust back end and it runs like the wind
Thank you for posting this. Trying to get this to work. I have a few questions.
PREDICT=numbatch # bash script in this directory that does all the dowloading, processing and uploading
Is this my own .py script (model)? Should I have a standalone python or can i reference utils?
NAPI=/home/l/.local/bin/numerapi # absolute path/name of fully installed numerapi CLI (python) script
Is this the python package or my own .py script?
Thank you sir.

Thank you very much. Fingers crossed. It appears to be properly set up.

You are welcome. It works well for me.
The problem I have are the unpredictable times of the tournament start.
I could leave cron running and it would do it at the right time but
it is around midnight here and I want to switch my big computer off and go to bed.
If it at least was at the originally promised 13:00 UTC, it would not be so bad.
It has been a while, so here is my latest version with some improvements:
#!/bin/bash
# Sets up crontab that checks for and runs numerai tournaments.
# Local timezones are automatically taken care of.
# `./cronrun d` sets up crontab for daily runs (Tue-Fri, 13:00 UTC).
# `./cronrun w` sets up crontab for weekly runs (Saturdays, 18:00 UTC).
# `./cronrun b` sets up crontab entries for both daily and weekly runs.
# Can also be activated immediately manually, with `./cronrun daily` or
# `./cronrun weekly`, when crontab was not previously set up.
# After the activation, will be waking up at the specified MINS intervals,
# checking for new tournament and then running the processing script.
# Tue-Fri runs script named `daily`,
# on Saturdays runs script named `weekly`.
# Both `daily` and `weekly` scripts must be present in the same directory.
# Activate only once, verify with `crontab -l`, cancel with `crontab -r`.
# Your computer and internet connection must be on at the local target time.
