from prefixspan import PrefixSpan

db = [ [0, 1, 2, 3, 4], [1, 1, 1, 3, 4], [2, 1, 2, 2, 0], [1, 1, 1, 2, 2], ]

ps = PrefixSpan(db)

print(ps.topk(5, generator=True))

using Ipython notebook.

Issue in upstream dependence extratools. Will fix soon. Thank you for reporting.

Wow you are fast! Just wanted to report the same, thanks for going after it!

chuanconggao commented 6 years ago

Updated extratools to 0.8.1 and bumped PrefixSpan-py to 0.5.2. The issue should be fixed. Please update your local versions.

Thank you. Please let me know if there is any further issue.
