HLearn [0] could be a difficult case: it depends on [1] which says it is deprecated in favour of [2]. Note that all three are by the same github user so the only way forward (for installation help) would be to ask him.
The detailed answer about running code etc. I will leave to the TA correcting your lab.
About the "re-lab" opportunity: Yes, there will be a possibility also in 2015. The dates have not been set yet but I include below the description from 2012 which should be similar this year.
For those of you who have tried but not passed the AFP labs I have
decided to offer a "re-lab" opportunity in August (around the time for the
written re-exam 2013-08-26 [1]). If you are interested, you need to hand
in your lab solution(s) by email and "book" a presentation / oral exam
time when I can make it.
The deadlines are B, D and D+2
* let B <= 2013-08-12 for "booking" a presentation slot
* pick 2011-08-12 <= D <= 2011-08-28 for handing in the lab(s)
* then D+2 is the day for the presentation slot
Or in words:
1. register your intent to do a re-lab no later than 2013-08-12
2. I will assign you an "oral lab-exam" slot
3. hand in your lab solutions no later than two days before the "oral lab exam"

PS. The re-exam 2012-08-26 follows the usual pattern with registration etc. handled by the central admin.
