【问题描述】：
我正在创建一个仪表板并使用 xlsx 文件作为数据源。 Dashbaord 有两个输入和一个输出。 输入是
- 下拉菜单
- 单选按钮
输出是
- 树形图
某些下拉选项的输出效果很好，但少数选项会引发以下错误
ValueError: invalid literal for int() with base 10: '(?)'
我的代码如下。
import dash
import dash_core_components as dcc
import dash_html_components as html
import plotly.express as px
import pandas as pd
from dash.dependencies import Input, Output
vault= pd.read_excel('Single Date BNV & CNV.xlsx')
vault['Deposit Date']= vault['Deposit Date'].dt.date
app = dash.Dash()
head = html.H1('WELCOME TO DASHBOARD')
head_style ={'textAlign':'center'}
c_bank = vault['Bank'].unique()
cb_banks = dcc.Dropdown(id='bank_dd',
options=[{"label": bank, "value": bank} for bank in c_bank],
multi=True,
placeholder="Select a Bank",
style={'width':'500px','margin':'5px'})
color_options = ['Deposit Date','Denom']
color_option = dcc.RadioItems(id='color_option1',
options=[{"label": color, "value": color} for color in color_options],
value='Denom',
style={'width':'500px','margin':'5px','label':'Color by'},
labelStyle={'display': 'inline-block'},)
tm1 = dcc.Graph(id='tm1')
@app.callback(
Output(component_id='tm1', component_property='figure'),
[Input(component_id='bank_dd', component_property='value'),
Input(component_id='color_option1', component_property='value')])
def update_figure(selected_bank,color):
filtered_bank = vault[vault['Bank'].isin(selected_bank)]
fig = px.treemap(filtered_bank, path=['Vault', 'Bank', 'Category','Denom','Design','Safe ID','Value'], values='Pieces',
color=color,title='Deep Dive')
return fig
app.layout = html.Div([
html.Div([head],style=head_style),
html.Div([cb_banks,
html.Label(['Color By:']),
color_option]),
html.Div([tm1]),
],)
if __name__ == "__main__":
app.run_server(debug=False)
.info() 命令产生以下结果。

该应用程序保持运行状态并适用于少数选项。
【问题讨论】：
-
您在一个应该包含整数的字段中有字符串
(?)。 -
我不知道具体在哪里
-
发布错误的完整回溯。你能在没有那些空行和无用的
# In[XX]cmets 的情况下格式化代码吗？ -
我已更新代码并粘贴回溯。由于长度限制，无法完全添加 Traceback
-
假设你的 DataFrame 是
df，那么你可以在哪里找到(?)[df[df[col]=='(?)'] for col in df.columns]
