我有一個不同植物物種的數據集，並且我將每個物種分爲不同的np.array。 當試圖從這些物種中生成高斯模型時，我必須計算每個不同標籤的平均值和協方差矩陣。 問題是：在其中一個標籤中使用np.cov()時，該函數引發錯誤「'float'對象沒有'shape'屬性，我無法確定問題來自何處。

06.12.2021 · You can eliminate the AttributeError: ‘NoneType’ object has no attribute ‘something’ by using the- if and else statements. The idea here is to check if the object has been assigned a None value. If it is None then just print a statement stating that the value is Nonetype which might hamper the execution of the program.
