SSD - object detection

[RanushMithila]

this is the course "[DesireCourse.Net] Udemy - Deep Learning and Computer Vision A-Z™ OpenCV, SSD & GANs" .I'm learning this course but I got this error..how to fi it

ValueError: not enough values to unpack (expected 2, got 0)

I'm run this code in spyder(python 3.6)

detection.py line 49 indtead "if scores.dim() == 0:" with " if scores.size(0)==0:"

detection.py line 49 indtead "if scores.dim() == 0:" with " if scores.size(0)==0:"

it is didn't work sir Now I come this error

The course you are doing requires these. So create a new environment and install these: python version 3.6.10 pytorch version 0.3.1 torchvision version 0.1.6 pillow version 7.1.1 opencv-contrib-python version 4.2.0.34 opencv-python 4.2.0.34

I tried these and it was working.
