FileNotFoundError: [Errno 2] No such file or directory: '../annotations/person_keypoints_train2017.json'

[vishnukv64]

im getting this error, i followed all the steps properly and shifted everything to 80classes.

This error arises in:
raceback (most recent call last):
File "train.py", line 89, in
dataset = ListDataset(train_path, augment=opt.augment,use_mix=opt.mix_up, multiscale=opt.multiscale_training,normalized_labels=True)
File "/home/amvar/vishnu/YOLO_NANO/Yolo_Nano/utils/datasets.py", line 77, in init
self.annotations = COCO(json_root)
File "/home/amvar/vishnu/YOLO_NANO/venv/lib/python3.6/site-packages/pycocotools/coco.py", line 84, in init
dataset = json.load(open(annotation_file, 'r'))
FileNotFoundError: [Errno 2] No such file or directory: '../annotations/person_keypoints_train2017.json'

i really dont know where it went wrong, and why is it asking for a personkey train.json and not instance json.

Thanks in advance

you can modify it in config . it‘s traning set for human coco in 2017， espically for pose . of course pose means have human that’s why we use it to train our model.

the config youre talking about, is it the yolo-nano.cfg or yolo-nan-person.cfg...

coz i dont want only person, i want to train for the whole 80 classes, with coco 2014 dataset and not 2017 dataset..

btw thanks for your fast reply .

sorry, i can not find where to modify it...

Hi,
you can try to modify "data/default_path.py"->coco_train path.
ex:
"coco_train": {
"img_dir": "data/coco/images/train2014/",
"annotations":"data/coco/annotations/instances_train2014.json"
}

And the path of the dataset must be created in accordance with the coco-format.

data
|___coco
　　|__________annotations
　　　　 |____instances_train2014.json
　　　　|____instances_val2014.json 　　|__________images
　　　　 |____train2014
　　　　 |____val2014

It works for me.

我按照你的思路改了一下，在Evaluating Model时报错FileNotFoundError: [Errno 2] No such file or directory: '../annotations/person_keypoints_val2014.json'，但是我在default_path.py中更改了coco_test路径为"data/coco/annotations/person_keypoints_val2014.json"

Hi @Xerus-git
I did the same changes to train the model with all the 80 classes. But I end up with this error: RuntimeError: The size of tensor a (80) must match the size of tensor b (27) at non-singleton dimension 1 Do you know what might be causing this error? Thanks in advance.
