Replying to [comment:4 kcrisman]:
> I did `./sage -ba` to get rid of the erroneous errors (that would
include the file you refer to). I'll upload an updated version of that
part of the log. Also, there *was* internet connection (had to have it to
download it, and also to get the gap package I didn't realize I needed
until it told me so), but it is true I have never computed these before or
used the spkg before.
Yes, probably that's why. I moved my old data out of the way, and then I
got a couple of errors. It turned out that this could be resolved by doing
{{{CohomologyRing.user_db(...)}}} when I did {{{CohomologyRing(...)}}}
(the latter did access old data).
> As far as I can tell, the second run had the same failures, but I
didn't bother to check all of them by hand.
Yes, no surprise. My erroneous tests assumed that you had data on your
computer obtained by ''previous'' versions of the package.
> Finally, here is one of the typical failures replicated. I can check
some other stuff (possibly not until rather later, though) if you give
very explicit instructions as to what commands to run.
Thank you! I'll see if I can somehow replicate the error.
Does the error also occur if you do
{{{
sage: from pGroupCohomology import CohomologyRing
sage: tmp = tmp_filename()
sage: CohomologyRing.set_user_db(tmp)
sage: G = gap('AlternatingGroup(8)')
sage: H = CohomologyRing.user_db(G,prime=2,GroupName='A8')
}}}
?
Best regards,
Simon
