Segmentation fault #55

Closed redredraccoon closed 3 years ago

redredraccoon commented 3 years ago

您好，在使用pre-trained weight 做 train的步驟時，出現Segmentation fault的錯誤訊息(如下所示) 已使用cuda 10.0、並使用gpu來跑，想請問能否給提示呢? 謝謝

你好 redredraccoon，

感谢你的提问！建议你试着用pdb单步跟踪一下错误具体出现在哪行。

redredraccoon commented 3 years ago

您好，我使用pdb後，發現HybridPose/trainers/coretrainer.py的572行出現error(如下圖所示) image 想請問您是使用gcc 4.9(或以上)的版本嗎? python版本是使用3.7.4嗎? 謝謝~

你可以单步跟到vote_keypoints这个函数里看一下吗？

redredraccoon commented 3 years ago

您好， 從HybridPose/src/train_core.py追蹤到HybridPose/trainers/coretrainer.py的vote_keypoints函數， 再追蹤到HybridPose/lib/ransac_voting_gpu_layer/ransac_voting_gpu.py， 發現是cur_hyp_pts = ransac_voting.generate_hypothesis(direct, coords, idxs)這行出現error message(如下圖所示) 進去ransac_voting_gpu.py查看後，並無查到generate_hypothesis的函式， 我認為此函式是源自"/home/ubuntu/HybridPose/lib/ransac_voting_gpu_layer/src/ransac_voting.cpp"，猜測無法順利啟用此函式的原因是gcc/g++版本與作者不同，所以想請問您是使用gcc 4.9(或以上)的版本嗎? python版本是使用3.7.4嗎? 謝謝 image image

python 的版本是 3.7.4 。我猜测是 nvcc 没有配置好，你可以再试试。实在不行的话，可以发邮件给我，约个时间远程用 zoom 看一下。
