ValueError：形状は[ROIAlign/Crop]（op： 'CropAndResize'）の入力シェイプ：[2,360,475,3]、[1,4]、[]、[2]のランク1である必要があります。

Iこの関数にすべての入力を与えようとしましたが、以下のような問題が出てきます。空の[]が何であるかわかりません。 RGBに2つの画像イメージがあり、元のコードはhttps://github.com/CharlesShang/FastMaskRCNN/blob/master/libs/layers/crop.pyです。ValueError：形状は[ROIAlign/Crop]（op： 'CropAndResize'）の入力シェイプ：[2,360,475,3]、[1,4]、[]、[2]のランク1である必要があります。
