Association rule troubles and mitigation ideas

[rasbt]

Hi all,

I received many emails about the association rule function in recent weeks. It seems to cause some various issues for some, and my apologies for that. I was also out for almost 2 months due to a travel injury and there are many other priorities I have to catch up on at the moment, so I am not sure when I will have the time to investigate this.

My suspicion is that the discrepancies you are getting (higher memory usage etc) has something to do with the 2 recent releases:

thanks for the email and note. Unfortunately, I currently don’t have the capacity to investigate further, but I suspect it had something to do with the improvements that have been made to the association rule function in the 2 recent releases in 0.23.2 and 0.23.3. (For reference, you can see there were some changes introduced in 0.23.2 and 0.23.3: https://github.com/rasbt/mlxtend/releases)

I am not sure when I will have the time to investigate more, but for an immediate solution, I suggest you try an older version. For example,

pip install mlxtend==0.23.1 -U

and see if this addresses the issue and reproduces your previous results.

I would definitely appreciate any PRs that would help mitigate potential problems here. In the worst case, I can also see if I can roll back some of the changes in the upcoming weeks or so.

I think this is the commit introducing the issue #1106.

Thanks, I think you may be right. If I have the time in a few days, it would be good to re-roll back this PR to fix the common user issues. And then maybe revisit this PR more carefully. Maybe it should be a separate

If you have time and would like to contribute, PRs are always supported and appreciated, since I unfortunately have very limited time to maintain this package.

I think the issues should be fixed now as of the latest release :)
