I can't load pictures

❓ Questions and Help

When I try train_net.py with COCO datasets according to the README.
I can't load pictures like below. The pic exists in val_2014 directory.
Do you have idea about it ?
So I'm sorry if I asked questions about strange things.
Thank you for in advance.

Did you do the symlinks as explained in the README? And are you running the code from the maskrcnn-benchmark folder?
