我是 plotly dash 的新手,并试图运行这个谷歌代码来理解输出。当我在 windows cmd 提示符下运行以下代码时,执行返回 URL-- http://127.0.0.1:3003 在 Chrome 浏览器中粘贴上述代码时,浏览器窗口中会显示错误加载依赖项。请在代码下方找到。

pv = pd.pivot_table(df, index=['Name'], columns=["Status"], values=['Quantity'], aggfunc=sum, fill_value=0)
trace1 = go.Bar(x=pv.index, y=pv[('Quantity', 'declined')], name='Declined')
