AP=0 and AR=0 in COCO datasets

[Kangzf1996]

During the training, AP is always 0. btw, I use the COCO datasets.

And I use this command, python tools/train.py -f exps/example/yolox_s.py -b 64 --fp16 -o

Is this the result for 10th epoch?

yes @Joker316701882

@kikyoyang Please check your data. We can get proper training results using the current code.

I used the COCO datasets. The data is ok.

请问你解决这个问题了吗？我也遇到这个问题。

@kikyoyang I meet the same problem. I fix this by delete the cache data and rerun the experiments, which works for me!

cache data path: path_to_coco/img_resized_cache_train2017.array

please be aware of the following logs:

thanks, your answer is exactly for what I encountered. what if after I deleted it, it still ask to cache again?
