ema? I've never seen that.
You should have ...best.weights, ...last.weights, and ...final.weights.
"best" is the best one. You'll get that if you train with a valid.txt file and -map
. See: https://www.ccoderun.ca/programming/darknet_faq/#training_command
Last is the most recent (last) one to be written to disk.
Final is the one that comes at the very end training. If you md5 last and final, you'll see they are the same once you finish training.

hmm.. i trained yolov4-csp-custom. Then i got like this.
Never seen that before. But I stick mostly to YOLOvX.cfg and YOLOvX-tiny.cfg. Looking at the code, I do see functions like save_convolutional_weights_ema()
and is_ema_initialized()
.
Must be specific to some of the newer configs, because looking through the 40 or so neural network directories on this computer, I don't have a single instance of a "ema" file.
stephane@2004-dev ~/nn> find . | grep ema
stephane@2004-dev ~/nn [0|1]> find . | grep weights | wc -l
95
i found this line in darknet.c file
and explain about ema is this link https://pytorch.org/blog/pytorch-1.6-now-includes-stochastic-weight-averaging/
@stephanecharette @Wooks-git when you train yolov4-csp-swish model you will get that ema weight, The best model having highest MAP compared last,ema weight , inside cfg of csp-swish you will get this ema parameter, but im not sure whats the purpose of ema
when i trained model, i get model-[iter].weights, model-ema.weights, model-last.weights, model-final.weights.
what is different between ema, last, final??
