Hii, I am new to mmdetection and want to get the validation loss. I found this #505.
I added workflow = [('train', 1), ('val', 1)] but then I get this error
File "tools/train.py", line 247, in <module>
main()
File "tools/train.py", line 226, in main
'pipeline', cfg.data.train.dataset.get('pipeline'))
File "/home/mm/miniconda3/envs/mmdet/lib/python3.8/site-packages/mmcv/utils/config.py", line 52, in __getattr__
raise ex
AttributeError: 'ConfigDict' object has no attribute 'dataset'
I am also not sure how to set this "Also you need to modify the data_loaders in this line, your need to append your valset_loader at the end of data_loaders", because in version 2.28.2 the data_loaders looks different. In version 2.28.2 there is no _dist_train function, here it looks like this:
def train_detector(model,
dataset,
cfg,
distributed=False,
validate=False,
timestamp=None,
meta=None):
cfg = compat_cfg(cfg)
logger = get_root_logger(log_level=cfg.log_level)
# prepare data loaders
dataset = dataset if isinstance(dataset, (list, tuple)) else [dataset]
runner_type = 'EpochBasedRunner' if 'runner' not in cfg else cfg.runner[
'type']
train_dataloader_default_args = dict(
samples_per_gpu=2,
workers_per_gpu=2,
# `num_gpus` will be ignored if distributed
num_gpus=len(cfg.gpu_ids),
dist=distributed,
seed=cfg.seed,
runner_type=runner_type,
persistent_workers=False)
train_loader_cfg = {
**train_dataloader_default_args,
**cfg.data.get('train_dataloader', {})
}
data_loaders = [build_dataloader(ds, **train_loader_cfg) for ds in dataset]
Can somebody help me to get the validation loss in mmdetection version 2.28.2?
