使用带有选项 manual=True 的 ipywidget interactive()

Question

我正在将带有交互式小部件的 jupyter 笔记本更新到更新的版本（ipywidgets 7.2.1）。

它曾经有interactive() 功能，通过单击按钮手动执行（功能__manual=True）。但是现在我无法重现相同的行为。

这是一个最小的例子：

from ipywidgets import interactive, interact_manual
import ipywidgets as widgets

def do_sth(x):
    #do sth with the argument passed
    print("done "+str(x))

nb = widgets.BoundedIntText(description='Number:')

#Interaction in accordion nested in a tab
tab = widgets.Tab()
tab.set_title(0, 'Page 1')

#old method 
#problem: it is not manual anymore
w = interactive(do_sth, x=nb, __manual=True)

#new solution 1
#problem: the widget appears also outside the tab/accordion
w1 = interact_manual(do_sth, x=nb)
w1.widget.children[1].description = 'do sth' #seems a bit of a hack

#new solution 2
w2 = interactive(do_sth, x=nb, manual=True) #does no pass the manual option
#if I set it manually with:
#w2.manual = True 
#It generates an error (AttributeError: 'interactive' object has no attribute 'manual_button')

accordion = widgets.Accordion(children=[w, w1.widget, w2])
accordion.set_title(0, 'old interaction 0')
accordion.set_title(1, 'new interaction 1')
accordion.set_title(2, 'new interaction 2')

tab.children = [accordion]

tab

是否可以使用解决方案 1 并防止小部件出现两次？否则，还有其他方法吗？

Answer 1

似乎他们在添加重新标记按钮的功能时已将其移动到字典中。

试试

w2 = interactive(do_sth, {'manual' : True, 'manual_name' : 'Do Something'}, x=nb)
