YOLOv4-CSP Average Precision

[tkbchan]

I'm using this Scaled YOLOv4 to train a customized model. I followed the command for test.py but all I got was P, R, mAP .5 and .95.

In the readMe file of your repository, I saw that your test.py showed this:

Average Precision  (AP) @[ IoU=0.50:0.95 | area=   all | maxDets=100 ] = 0.51244
 Average Precision  (AP) @[ IoU=0.50      | area=   all | maxDets=100 ] = 0.69771
 Average Precision  (AP) @[ IoU=0.75      | area=   all | maxDets=100 ] = 0.56180
 Average Precision  (AP) @[ IoU=0.50:0.95 | area= small | maxDets=100 ] = 0.35021
 Average Precision  (AP) @[ IoU=0.50:0.95 | area=medium | maxDets=100 ] = 0.56247
 Average Precision  (AP) @[ IoU=0.50:0.95 | area= large | maxDets=100 ] = 0.63983
 Average Recall     (AR) @[ IoU=0.50:0.95 | area=   all | maxDets=  1 ] = 0.38530
 Average Recall     (AR) @[ IoU=0.50:0.95 | area=   all | maxDets= 10 ] = 0.64048
 Average Recall     (AR) @[ IoU=0.50:0.95 | area=   all | maxDets=100 ] = 0.69801
 Average Recall     (AR) @[ IoU=0.50:0.95 | area= small | maxDets=100 ] = 0.55487
 Average Recall     (AR) @[ IoU=0.50:0.95 | area=medium | maxDets=100 ] = 0.74368
 Average Recall     (AR) @[ IoU=0.50:0.95 | area= large | maxDets=100 ] = 0.82826

which I don't get when I use the test.py. All I get is

Class	Images	Targets	P	R	mAP@.5	mAP@.5:.95:
all	80	170	0.0143	0.0824	0.00593	0.00102

please install pycocotools and put coco style gt file as https://github.com/WongKinYiu/ScaledYOLOv4/blob/yolov4-large/test.py#L228

If I install pycocotools with this

!pip install pycocotools-windows 

Then what should I do next? I'm using google colab

This is what happened when I used test.py

I still didn't get this

set opt.save_json = True https://github.com/WongKinYiu/ScaledYOLOv4/blob/yolov4-large/test.py#L264

[tkbchan]

I got a JSON file. What should I do with it?

I'm still not getting this

hey @WongKinYiu thank you for your great work I have followed your directions and i am getting coco style results byt the AP values are way less than the ones without --save-json command.

i am getting APs , APm, APl in decimals like 0.0001 which is not right.

Can you please guide

my mAP is 0.66 without save-json= true. I need coco format results for my APs(average precision small)
