Sample random genotypes

[bknyaz]

Hi,
I would like to just sample random genotypes using your code without learning alphas_normal, alphas_reduce.
I'm using the following code and it seems to work fine. Just wanted to check in if you can notice any caveats with using it or suggest a simpler approach.

set_random_seed(111)  # some function to set seed everywhere
steps = np.random.randint(1,5)
model = cnn.model_search.Network(n_ch, n_classes, n_layers, criterion,
                                 steps=steps, multiplier=steps)  # multiplier seems to be required to be equal steps
genotype = model.genotype()  # random genotype
