after training completion of all epochs , its crashing, not able to get final map,best.pt weight

[akashAD98]

i can able to do complete all training, once it reaches to last epoch its throwing an error & not able to get map,

also can we do testing of the trained model using detect.py?

the weight file size is 259 MB , I guess weight files are not downloading properly or they are corrupt.
i tested it with detect.py & getting
