尝试使用 Dash 运行简单仪表板时出现错误。我将 Spyder 与 Python 3.4 一起使用。我已经pip installed
dash, dash_core_components, dash_html_compenents
..
我的代码:
import dash
import dash_core_components as dcc
import dash_html_components as html
app = dash.Dash()
app.layout = html.Div(children=[
html.H1(children='Hello Dash'),
html.Div(children='''
Dash: A web application framework for Python.
'''),
dcc.Graph(
id='example-graph',
figure={
'data': [
{'x': [1, 2, 3], 'y': [4, 1, 2], 'type': 'bar', 'name': 'SF'},
{'x': [1, 2, 3], 'y': [2, 4, 5], 'type': 'bar', 'name': u'Montréal'},
],
'layout': {
'title': 'Dash Data Visualization'
}
}
)
])
if __name__ == '__main__':
app.run_server(debug=True)
我收到以下错误:

尝试查看示例仪表板时,它不会加载。
我已经尝试过此操作以解决此问题,但无法使其正常工作。
