Question

我正在使用小部件来参数化一些数据的生成。我想捕获数据，而不输出它。这可能吗？在D/NuPlayerDriver( 1144): start(0xb6250ca0) I/GenericSource( 1144): start I/Process ( 1498): Sending signal. PID: 1588 SIG: 3 I/Process ( 1498): Sending signal.

interact()

Answer 1

您可以修改全局变量，而不是在generate_data()中返回值。它可以避免打印输出，您可以稍后在代码中使用val。

import ipywidgets as widgets
from ipywidgets import interact, interactive, fixed
import numpy as np

val = None
def generate_data(n, p, s):
    global val
    val = np.random.negative_binomial(n, p, s)

w_n = widgets.IntSlider(min=1, max=10000, step=1)
w_p = widgets.FloatSlider(min=0.01, max=1, step = 0.01)
w_s = widgets.IntSlider(min=500,max=10000,step=50)

interact(generate_data, n = w_n, p = w_p, s = w_s)

Answer 2

我已经向ipywidgets提交了解决此问题的拉取请求：

https://github.com/ipython/ipywidgets/pull/712

这些变化实际上非常简单。使用此版本，您只需将额外的kwarg传递给interact：

data = interact(generate_data, n = w_n, p = w_p, s = w_s,
                __output_result=False)

禁止来自interact（）小部件的输出
