由表示数组的 dtypes 或可转换为 dtype 的对象组成的列表。 scalar_types序列 由表示标量的 dtypes 或可转换为 dtype 的对象组成的列表。 返回: datatypedtype 共同的数据类型,即array_types中的最大值,忽略scalar_types,除非scalar_types的最大值属于不同种类(dtype.kind)。如果该种类不被理解,则返回 None。 另...

If the (deprecated)NPY_ARRAY_UPDATEIFCOPYor theNPY_ARRAY_WRITEBACKIFCOPYflags are set, it has a different meaning, namely base is the array into which the current array will be copied upon copy resolution. This overloading of the base property for two functions is likely to change in a ...
