TypeError: sequence index must be integer, not 'slice' The TypeError shows that a deque can only be indexed using an integer, and a slice can’t be used in the square brackets. Deques are optimized to provide e
1、sequence是定义了__getitem__()和__len__()函数的可迭代对象,内置序列有list、str、tuple、bytes,dict虽然也实现了__getitem__()和__len__()函数,但它是映射类型。 2、抽象基类collections.abc.Sequence中定义了许多接口如count(), index(), __contains__(), and __reversed__()可用于扩展。 coll...
通过这种方式,我们成功地解决了TypeError: new(): data must be a sequence (got float)错误。现在我们可以将数据用于训练机器学习模型,实现图像分类的任务。 总结: 在实际应用中,当遇到TypeError: new(): data must be a sequence (got float)错误时,我们可以根据具体的应用场景,...

Aniterablewhich supports efficient element access using integer indices via the__getitem__() special method and defines a__len__()method that returns the length of the sequence. 从定义里可以看出,sequence首先是iterable。如果这个iterable可以通过整数索引来访问其元素并可以获 ...
It shows how to use an integer_sequence to create a std::tuple from a std::array<T,N>, and how to use an integer_sequence to get at the tuple members.In the a2t function, an index_sequence is an alias of integer_sequence based on the size_t integral type. make_index_sequence ...
…ors. (apache#13880) * Adding integer index support to Sequence* family of operators. Adding ability to use int32 arrays, or any castable-to-int type, as the sequence_length array to SequenceMask, SequenceLast, and SequenceReverse. Previously these operaters all requred sequence_length to be...
