Question

我试图在本地运行示例dash应用程序代码，但在打开窗口时总是会出错。

我正在使用Jupyter Notebook，有时使用PyCharm进行测试。我正在运行的代码是这样的：

import dash
import dash_core_components as dcc
import dash_html_components as html
import dash_bootstrap_components as dbc
import plotly
import plotly.graph_objs as go                # for making plot.ly graph objects
from dash.dependencies import Input, Output
from collections import deque
import random

X = deque(maxlen = 20)
X.append(1)
Y = deque(maxlen = 20)
Y.append(1)

app = dash.Dash(__name__) 

# Layout
app.layout = html.Div([
    dcc.Graph(id = 'live-graph', animate = True),
    dcc.Interval(id = 'graph-update', interval = 1000)
])

# Callbacks
@app.callback(Output('live-graph', 'figure'),
              [Input('graph-update', 'n_intervals')])

def update_graph(input_data):             
    
    X.append(X[X[-1] + 1])                                  
    Y.append(Y[Y[-1] + (Y[-1]*random.uniform[-0.1, 0.1])])  
               
    data = gp.Scatter(
        x = list(X),               
        y = list(Y),               
        name = 'Temperature',      
        mode = 'lines + markers'   
    )
               
    return {'data':[data], 'layout':go.Layout(xaxis = dict(range = [min(X), max(X)]),
                                              yaxis = dict(range = [min(Y), max(Y)])
                                              )}

if __name__ == "__main__":
    app.run_server(host = '0.0.0.0', port = 8050, debug = True)

我已经尝试将端口更改为8050并调试= False。 Image Error

Answer 1

如果您使用的是0.0.0.0:8050，则应该访问localhost:8050上的站点。

在本地运行Dash应用时出错，“无法访问此网站”
