There is a bug in detection_map_op.

[qingqing01]

Paddle/paddle/fluid/operators/detection_map_op.h

Lines 282 to 294 in 928730b

	auto SetData = [](const framework::LoDTensor& pos_tensor,
	std::map<int, std::vector<std::pair<T, int>>>& pos) {
	const T* pos_data = pos_tensor.data<T>();
	auto pos_data_lod = pos_tensor.lod();
	for (size_t i = 0; i < pos_data_lod.size(); ++i) {
	for (size_t j = pos_data_lod[0][i]; j < pos_data_lod[0][i + 1]; ++j) {
	T score = pos_data[j * 2];
	int flag = 1;
	if (pos_data[j * 2 + 1] < kEPS) flag = 0;
	pos[i].push_back(std::make_pair(score, flag));
	}
	}
	};

The line 286 should be:

for (size_t i = 0; i < pos_data_lod[0].size(); ++i) {

not

for (size_t i = 0; i < pos_data_lod.size(); ++i) {
