私はスライダー、ユーザー入力とテーブルの間の依存関係を取得しようとしています。データを出力し、コールバックを使用して更新しました。私はコールバックでテーブルを作成し、「div」を使用するだけで勧められました。ディスプレイ内の位置を定義するには。
他の情報:
threshold
がユーザー入力(スライダまたは入力)によって調整された値です。誰かが私がテーブルが表示されていない理由を見つけるのを助けることができるならば、私は感謝するでしょうか?
これが私のコードです:

import dash_table

私はこれを試してみましたが、上記のわずかに変更されたコードがわかりやすいようです。私が作らなければならなかった変化は次のとおりです。
table_data
をデータフレームに変換する(これにより、PD.DataFrameメソッドである.to_dict()
メソッドが機能します。) table_data = pd.DataFrame.from_dict(
{
"AUC": [threshold * 0.8, threshold * 0.83],
"Accuracy": [threshold * 0.85, threshold * 0.86],
"Kappa": [threshold * 0.66, threshold * 0.69],

"Precision": [threshold * 0.78, threshold * 0.79],
"F1": [threshold * 0.81, threshold * 0.82],
}
)
update_output
コールバックFXNでも:
id
ダッシュパラメータの使用を取り除く、B/Cはすでにレイアウトにあります return html.Div(

dash_table.DataTable(
