how i can fix internal change in number of elements in yolo v4 network while training

Error using reshape

Number of elements must not change. Use [] as one of the size inputs to automatically calculate the appropriate size for that dimension.

I have single class dataset withy class name person and this is error i am facing a time of training, i have gpu compute capacity 5.2 with gpu Nvidia M400

what could be issue here , i am cofuse that is it with preprocessing or compute capacity

Clearly this error is happening deep inside an internal function which the user cannot edit.

Maaz, what is your training data and responses? My guess is that your training targets do not match the data. You will need to provide more code.

i got it, it was the issue in My training Data.. Thanks !
