Keras で高密度フィードフォワード ニューラル ネットワークを実行します。2 つの出力には class_weights があり、3 番目の出力には sample_weights があります。何らかの理由で、計算された各バッチの進行状況の詳細な表示を出力し、想定されているのと同じ行で出力を更新しません...これはあなたに起こりましたか? それはどのように修正されますか？シェルから:

@user11353683 と @Panos のソリューションは、ソースを変更せずに完了することができます (将来の問題を引き起こす可能性があります):ipykernelコードにインストールしてインポートするだけです:

pip install ipykernel それで import ipykernel

実際、Keras の generic_utils.py ファイルでは、probematic 行は次のとおりでした。

            if self._dynamic_display:
                sys.stdout.write('\b' * prev_total_width)
                sys.stdout.write('\r')
            else:
                sys.stdout.write('\n')

そして値 self._dynamic_display は次のように開始されました:

        self._dynamic_display = ((hasattr(sys.stdout, 'isatty') and
                                  sys.stdout.isatty()) or
                                 'ipykernel' in sys.

そのため、ロードするとipykernelそれが追加さsys.modulesれ、問題が修正されました。

同様の問題がありましたが、さらに調査する時間がありませんでした。この問題は、keras の generic_utils.py のクラス Progbar に関連しているようです。リンクを参照してください。おそらく Python >= 3.3.

次の行は、クラスの update 関数にあります。

107行目: sys.stdout.write('\b' * prev_total_width)
108行目:sys.stdout.write('\r')

簡単な修正として 107 行目を削除しただけなので、前の行をバックスペースしてから行頭にシフトする代わりに、シフトのみを実行します。ただし、ソースコードを変更するよりも良い方法がいくつかあると思います。
