Error during running yolov4_publisher.launch
Hi! Got new OAK-D-Lite today, must say you guys did a great job! But faced error when launch yolov4_publisher.launch on ROS Noetic:
Error says:
Stack trace (most recent call last) in thread 3105: #5 Object "[", at 0, in nil #4 Object "/lib/x86_64-linux-gnu/libpthread.so.0", at 0x7f2047feb3bf, in #3 Object "/usr/local/lib/libdepthai-core.so", at 0x7f204744c76e, in backward::SignalHandling::sig_handler(int, siginfo_t*, void*) #2 Object "/usr/local/lib/libdepthai-core.so", at 0x7f204744c67d, in backward::SignalHandling::handleSignal(int, siginfo_t*, void*) #1 Object "/usr/local/lib/libdepthai-core.so", at 0x7f2047449e5f, in backward::StackTraceImpl<backward::system_tag::linux_tag>::load_here(unsigned long, void*, void*) #0 Object "/usr/local/lib/libdepthai-core.so", at 0x7f204744cb97, in unsigned long backward::details::unwind<backward::StackTraceImpl<backward::system_tag::linux_tag>::callback>(backward::StackTraceImpl<backward::system_tag::linux_tag>::callback, unsigned long) Segmentation fault (Address not mapped to object [(nil)])
Every launch of yolo ends with this, or with freezing when no image and no data in topic with detected objects.
Hi! I'm trying to reproduce the error on my system, and I couldn't make it. Do you use other OAK-D cameras on that system? Do you use an USB2 port? If so, can you try on USB3? Did you tried to change the cable?
Hi! Just tried on different OAK-D-Lite, cable and PC - no such behavior. Will try again on first one and with different cable. Hope problem is not in device itself.
