Following up on the discussion here, it would be good to document how to get reproducible results with UMAP.

I think we should consider changing random_state in the UMAP constructor to a seed (e.g. 42, like the new transform_seed default) so that UMAP is reproducible by default.

We should document that users can set `ran

Test code:

from sklearn.datasets import load_digits
from gtda.homology import CubicalPersistence
from gtda.diagrams import PairwiseDistance

X, _ = load_digits(return_X_y=True) 
nb_samples = 100
CP = CubicalPersistence(homology_dimensions=(0, 1))
X_diag = CP.fit_transform(X[:nb_samples].reshape(nb_samples, 8, 8))
PD = PairwiseDistance(
    metric='bottleneck', metric_params={'delta'

In Representative Cocycles tutorial, this code block

result = ripser(x, coeff=17, do_cocycles=True)
diagrams = result['dgms']
cocycles = result['cocycles']
D = result['dm']

raises a KeyError: 'dm' since returned object doesn't have the key. The available keys are:

result.keys()
# ['dgms', 'cocycles', 'num_edges', 'dperm2all', 'idx_perm', 'r_cover']

Magnus Botnan is running RIVET on OS X in dark mode and reports that the numbers in the GUI's text boxes (for example, for slope and offset) are shown as white; but that background for the boxes is also white, so that the numbers are invisible.
