I've got same error when train the model.

1. I've checked the 'torch.cuda.**' and there's nothing wrong happend. ONLY at this happend. 2.I also have right cuda version

Any helps?

USED: cd python3 tools/train.py -f exps/example/mot/yolox_x_ablation.py -d 8 -b 48 --fp16 -o -c pretrained/yolox_x.pth

Check your machine has GPU OR make sure your pytorch has cuda version

[Melikamuliyih]

I've had got this problem too, and I had solved by downloading pytorch with cuda version and aslo try the with gpu device 0. instead of -d use -d 0

Thx a lot. I've tried following you. and I could see the "exp value" table. but still get an error as bellow. did this happend to you ?

Sorry, I didnt got this

Guess this was the problem. Thx. good day :)

Good

But I've got this problem

"yolox/data/datasets/mot.py", line 102, in pull_item assert img is not None AssertionError

[Dev-ori]

As for my experience, those 'AsserstionError's occured by 'yolox' version or packages. So, I'd solved by deleting yolox and packages. or simply just delelting the whole 'Bytetrack' folder and re-download and re install by the following steps noted at the 'readme.md'.

I guess there could be some collision between install steps.

and beaware that this 'Bytetrack' uses the old version of yolox

I also ran into this problem, were you able to solve it?

If you get warnnings, try to solve them

[forever208]

it is generally the issue of wrong image directoies, you can print out the dir for debugging.

[parthmalpathak]

Any other update on Solving this problem? I have tried pytorch with cuda version and it still doesn't work. Any other way round it or should I simply reinstall ByteTrack.

[TheMadScientiist]

@parthmalpathak In the dataset directory(../Bytetrack/datasets) , name your folder for your dataset “mot”

[parthmalpathak]

@TheMadScientiist just to confirm, the datasets folder already has 'mot' which contains MOT17- train, test and annotations. Apart from that can you tell me where to store mix_det, mix_mot_20_ch and mix_mot_ch? Because I have just kept them as directories along with ETHZ, cityscapes and other datasets

[TheMadScientiist]

@parthmalpathak In the ETHZ and cityscapes directories are there train, test, and annotations like the “mot” folder?

[parthmalpathak]

datasets |——————mot | └——————train | └——————test └——————crowdhuman | └——————Crowdhuman_train | └——————Crowdhuman_val | └——————annotation_train.odgt | └——————annotation_val.odgt └——————MOT20 | └——————train | └——————test └——————Cityscapes | └——————images | └——————labels_with_ids └——————ETHZ └——————eth01 └——————... └——————eth07

The folders are made the same way as suggested in the README. They have the same content. Each folder has annotations extra when you convert to COCO by running the .py files.

l change the d to 0, but l get this problem No such file or directory: 'pretrained/yolox_x.pth' , how to fix it

[5211314whb]

You can create a new folder in your root directory. Name it pretrained, and put yolox_x.pth in it

I also have the same problem, which has not been solved. Is there a bug in the original code?

any result? l have assert img is not None too

[silverAugustine]

maybe you can change the command line (e.g. from "python train_net.py --num-gpus 8(this num is too big) " to "python train_net.py --num-gpus 2(the number is up to your num of gpus, I recommand you to rise it from 1)")
