Comment (by bump):
There are doctest failures in non_symmetric_macdonald_polynomials.py.
There are quite a few but for example:
{{{
Failed example:
for d in range(1,2): # long time
(41s)
for a,b,c,d in !IntegerVectors(d,4):
weight = a*La![1]+b*La![2]+c*La![3]+d*La![4]
weight0 = -a*omega![1]-b*omega![2]-c*omega![3]-d*omega![4]
LS = crystals.ProjectedLevelZeroLSPaths(weight)
assert E[weight0].map_coefficients(lambda !x:x.subs(t=0)) ==
LS.one_dimensional_configuration_sum(q)
Exception raised:
