Ipywidget选择框不打开
我有一个Jupyter笔记本,并且正在使用leafmap。我想添加一个文件选择器,这样可以打开一个小工具来选择本地文件。我在一个单元格里写了以下代码:
import ipywidgets as widgets
from ipyfilechooser import FileChooser
import os
padding = "0px 0px 0px 5px"
style = {"description_width": "initial"}
tool_output = widgets.Output(
layout=widgets.Layout(max_height="150px", max_width="500px", overflow="auto")
)
file_type = widgets.ToggleButtons(
options=["GeoTIFF", "COG", "STAC", "Microsoft"],
tooltips=[
"Open a local GeoTIFF file",
"Open a remote COG file",
"Open a remote STAC item",
"Create COG from Microsoft Planetary Computer",
],
)
file_type.style.button_width = "110px"
file_chooser = FileChooser(
os.getcwd(), sandbox_path=m.sandbox_path, layout=widgets.Layout(width="454px")
)
file_chooser.filter_pattern = ["*.tif", "*.tiff"]
file_chooser.use_dir_icons = True
source_widget = widgets.VBox([file_chooser])
但是当我运行这个单元格时,没有出现选择框。我哪里出错了呢?
