は、コードの一部ですか？ 問題が2で除算されている可能性があります。 「h/2」と「w/2」をそれぞれ「h // 2」と「w // 2」に置き換えてください。

Answer 2

これは、スライスインデックスが浮動小数点型または2重型の場合、またはスライスの構文が正しくない場合に発生します。スライスのシンタックスまたはスライスインデックスのタイプを確認してください。

可能性のあるエラーの例は：

a = [1,2,3,4] 
a = a[1.2:] 
TypeError: slice indices must be integers or None or have an __index__ method 

a = a[1,2:] 
TypeError: slice indices must be integers or None or have an __index__ method 

a = a[1:2,3:4,:]
