DNNを使用してテンソルボードを使用して画像分類子を視覚化しようとしました。ディレクトリパスが正しいとは確信していますが、データは表示されません。私は私のコーディングに何かがなければならないと思っています「PATH /」にtensorboardがイベントファイルを見つけることができません
をLOGDIR内が見つかりませんイベントファイル：私は tensorboard --inspect --logdir='PATH/' 戻りを試してみました 。

私にとっては、「Go to X：\ first part」でした。 私はC：\でcmdを開きましたが、データはD：\にありました。明らかにその問題 – JBSnorro
