PyOpenCL | Не удалось запустить Kernel

Question

Когда я использую PyOpenCL для запуска ядра «SIMPLE_JOIN», он терпит неудачу.

ЗАГОЛОВОК ядра В .cl FILE

void SIMPLE_JOIN(__global const int* a, int a_col, __global const int* a_valuesPic, 
       __global const int* b, int b_col, __global const int* b_valuesPic, 
       __global const int* join_valuesPic, __global int* current, const int maxVars, __global int* buffer, int joinVar) 

исполнение в PyOpenCL

program.SIMPLE_JOIN(context, (a_col, b_col), None, \ 
        buffer_a, np.int32(a_col), buffer_a_valPic, \ 
        buffer_b, np.int32(b_col), buffer_b_valPic, \ 
        buffer_join_valPic, buffer_current, np.int32(maxVars), \ 
        buffer_result, np.int32(joinList[0])) 

ОШИБКА в командной строке

Первый аргумент вашего ядра вызова должна быть очередь команд, а не контекст:

program.SIMPLE_JOIN(queue, (a_col, b_col), None, \...
