I need a widget that takes in an array as input, i.e. something like a hundred sliders (that I don't want to create manually).
How can I achieve this?
I thought the answer would be widgets.Box, but then I get the error Box(...) cannot be transformed to a widget.
Got it -- the trick is to use **kwargs. My code looks something like this.
seed = np.zeros(100)
kwargs = {'seed[{}]'.format(i) :
widgets.FloatSlider(
min = -1.0,
max = 1.0,
step = 0.01,
value = seed[i])
for i in range(100)}
@interact(**kwargs)
def Generate(**kwargs):
return seed
A better solution will nonetheless be appreciated, because I don't know how to change the layout and stuff with this solution.
I think you need HBox or VBox, not just Box for a container.
import ipywidgets as widgets
from ipywidgets import interact
n = 10
seed = np.zeros(n)
sliders = list(widgets.FloatSlider(
description = 'seed[{}]'.format(i),
min = -1.0,
max = 1.0,
step = 0.01,
value = seed[i])
for i in range(n))
widgets.VBox(children = sliders)
