I ran into a tricky problem when running train_segmentation.py

I am getting an error for libffi.so.7:cannot open shared object file: No such file or directory；By the way, my environment is python38 and pytorch1.12, ubuntu system is 18.04, and my libffi version is 3.4.2；I‘m sorry to bother you.

Hmmm this looks like more of a pytorch install problem than a problem with the code. Try doing a simple smoke test with pytorch to debug your installion. Also try reinstalling pytorch according to the latest instructions for your machine d NVIDIA driver versions
