次のエラーコードを修正するにはどうすればいいですか？ValueError：テンソル 'InputData/X：0'の形状（ '、？、16,1）'の形状値（64,15）を入力できません

Question

予測を実行するためにLSTMニューラルネットワークを使用する。データセットはすべてのY値に対して16個のX値を持ちます。私が知る限り、列X &YアレイまたはテストX &Yアレイまたはその両方の形状に問題があることがわかります。私は再形成しようとしました、それは私の調整が正しくないようです。以下はJupyter Notebookのwith出力に沿ったコードです。あなたの洞察を事前にありがとうございます。

Answer 1

問題は、あなたがtrainXを作成しているとき、あなたは唯一の15個の値を取り、16

trainX = csvData[0:3360,0:15]を書いていないことだけで、あなたに二次元での最初の15個のチャンネルを与えることです。それをtrainX = csvData[0:3360,0:16]と交換してください。

あなたのテストデータには同じ問題があり、ボーナスはreshape dではありません。その結果、適切な次元数も存在しなくなります。
