scipy?

[themaddoctor]

scipy wasn't listed in requirements.txt, but although I was able to compile (had to run aclocal and autoconf before autoreconf), and although there were no complaints about it when building g6k, this is the result:

$bkz.py 180 --bkz/betas 60:95:1 --bkz/pre_beta 59 --trials 8 --workers 8
Traceback (most recent call last):
  File "/usr/bin/bkz.py", line 39, in <module>
    from g6k.algorithms.bkz import naive_bkz_tour, pump_n_jump_bkz_tour, slide_tour
  File "/usr/lib/python3.7/site-packages/g6k/__init__.py", line 24, in <module>
    from .siever import Siever  # noqa
  File "g6k/siever.pyx", line 29, in init g6k.siever
ModuleNotFoundError: No module named 'scipy'

So while I am no longer getting any "illegal instruction" errors, I cannot test any further at this time.

That's very bizarre. The requirements.txt file hasn't changed in the last 9 months, and even the version on the avx2-fix branch has scipy listed (see https://github.com/fplll/g6k/blob/f65e3a2db58ca876ddaa4b9d201a20a50702b8b2/requirements.txt#L9).

In any case: you should be able to fix this by running python -m pip install scipy inside your virtual environment.
