Server Errors on Friday

I am getting nothing but server errors today (Friday), when trying to download data with ‘numerapi’.

The competitions opened about half an hour late. That happens once in a while. If that was your problem, just put a loop in your script to check if the round is open, if not, wait 5 or 10 minutes and try again.

I have that already but after half an hour of failed attempts I thought the problem was perhaps in my script, so I turned the check off. My fault, I guess.

Other things to check when there’s a problem like this:

  • The Tournament or Signals web page. If there’s no submission panel showing, then it usually means there’s a problem on the Numerai end.
  • The support channel on the Chat. Numerai generally puts up notices there about what’s wrong and how long before it’ll be working again pretty quickly after a failure. See @pshork’s comment there at 13:08 UTC.

On the bright side, they do say the round will always be open for a full hour, regardless of when it starts.

Piece of code I have added to my script on Friday (while waiting for round openning):

from numerapi import NumerAPI
from time import sleep
from datetime import datetime

napi = NumerAPI(public_id="your_public_id", secret_key="your_secret_key")

# wait until current round is open and get current_round number
current_round = 0
while current_round == 0:
    print("Waiting for openning of current round at", datetime.now())
    try:
        if napi.check_round_open():
            current_round = napi.get_current_round() 
        else:
            sleep(60)
        
    except:
        sleep(60)

As I do not use Python, I have a Bash script:

#!/bin/bash
# Sets up cron checks for new numerai rounds TUE-FRI, from 13:05 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
