There was a problem hiding this comment.
这里不应该将int64_t改为int。因为对于大Tensor而言，任何一个维度的大小都有可能超过int的上限。

Description
roi_align函数输出Tensor的shape为 [box[0], input[1], pooled_height, pooled_width]，其中pooled_height, pooled_width 是都要大于0，所以需要对 input和box的numel为0时进行特殊处理。
修复前，存在cuda error(9) 问题，需要进行修复。
修复：
cuda error(9) 报错修复：
使用--paddle_only 和 --accuracy 选项时，出现numpy error错误（不做处理）
