How to delete element from Vector How to delete element from Vector: There is tricky thing for deleting in vector loop. The erase method returns the next element after the one you just erased. So you can use that to continue in your loop. vector c; iterator i = c.begin(); while(i ...
std::inplace_vectoriterator invalidation guarantees differ fromstd::vector: moving aninplace_vectorinvalidates all iterators; swapping twoinplace_vectors invalidates all iterators (during swap, the iterator will continue to point to the same array element, and may thus change its value). ...
ggml_mul_mat:矩阵乘加运算,如果未被转置,则拆解src0的行使用vector_add,否则拆解src1的列使用vec_mad,使用多线程的方式进行计算,在GGML_TASK_FINALIZE阶段将所有线程计算的部分和累加在一起。 ggml_scale:tensor放缩运算,z = y*scale ggml_cpy:对tensor拷贝,背后调用的tensor_dup函数 ...

Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: std::string for strings, int64_t, uint64_t or double for numbers, std::map for objects, std::vector for ...
