Copy link shawnLang commented May 8, 2021 1)PaddlePaddle版本:paddlepaddle-gpu:2. There are some repos about it but these are complicated, INFO: 172. You signed in with another tab or window. Could be a bug (like some data is not deallocated properly) or perhaps the given frame actually needs more memory than available. My test env is Ubuntu 22. an illegal memory access would be something that doesn’t fall within a valid location/range in local, global, or shared space. py script from ultralytics/yolov5 Description Hi Team, Looking for some help please.

LogicError: cuStreamSynchronize failed: an illegal memory access was encountered Does anyone know why about this? (this can be easily revealed, I got same problem on a classification model and a detection model) The text was updated successfully, but these errors were encountered: 最关键的,也是我遇到的问题,这个错误没有表明和显存溢出存在着联系,因为 显存溢出 会报 out of memory, 所以没有往那一方面去想。 后来发现的确是显存的问题,因为在一些任务中尤其是目标检测任务中,会生成很多bbox这些bbox需要map到GPU上才能计算!
