Hi there,
I am just a newbie in Pytorch. I cloned prajjwal1’s repository from here https://github.com/prajjwal1/autonomous-object-detection 1 and was trying to run it for bdd100k dataset. However, I keep getting this below error. It might be a simple error but I could not fix it. It is appreciated if you could help me.
