[lightninglarry]

Heres my code:
Pretty generic, but it cant get past 3

from pydfs_lineup_optimizer import get_optimizer, Site, Sport, CSVLineupExporter
from pydfs_lineup_optimizer.stacks import TeamStack, PositionsStack, PlayersGroup
from pydfs_lineup_optimizer import AfterEachExposureStrategy

optimizer = get_optimizer(Site.DRAFTKINGS_TIERS, Sport.FOOTBALL)

optimizer.load_players_from_csv(r"C:\Users\brand\Downloads\TiersWk3DKSalaries.csv")

lineups = optimizer.optimize(20,exposure_strategy=AfterEachExposureStrategy)
for lineup in lineups:
print(lineup)
optimizer.export(r"C:\Users\brand\Desktop\PYTHON\NFL\NFLFANDUEL.csv")
optimizer.print_statistic()

GenerateLineupException: Can't generate lineups. Following constraints are not valid: min_games

You have an error in min_games constraint, dk tiers settings have configs that at least 2 games must be used. How many games are in your csv?

[lightninglarry]

10 different games to choose from.
