With larger datasets I get an accuracy of Infinity with each decision tree

When I run this code on data sets of size 10000 and up I get an accuracy of Infinity and when the rules are printed Infinity is displayed instead of a decimal eg:

IF Outlook IS Sunny AND Temperature IS Mild AND Humidity IS Humid THEN Volleyball (Infinity)

After more testing it seems like the 'Infinity' error happens with certain data sets regardless of their size. It is most likely something to do with the values in the data set
