result index in show of test.py

https://github.com/open-mmlab/mmfewshot/blob/main/mmfewshot/detection/apis/test.py#L72
```
if is_module_wrapper(model):
    model.module.show_result(
        img_show,
        result[i],
        show=show,
        out_file=out_file,
        score_thr=show_score_thr)
```
should the index of result is j? result[j]?
I get an error: IndexError: list index out of range
