GREW pretreatment to_pickle has size 0

[gosiqueira]

I'm trying to run GREW pretreatment code but it generates no GREW-pkl folder at the end of the process.
I debugged myself and checked if the --dataset flag is set properly and the to_pickle list size before saving the pickle file.
The flag is well set but the size of the list is always 0.

I downloaded the GREW dataset from the link you guys sent me and made de GREW-rearranged folder using the code provided.
I'll keep investigating what is causing such an error and if I find I'll set a fixing PR.

Hi~ I guess you are using the newer OpneGait code.
If you want to run GREW successfully, you have two options:

1. Please download the source code for this repo and run sh misc/run_pretreatment_grew.sh with the original directory structure that GREW decompressed.
   Then, please refer to the train /test file and rewrite the command as follows:
   For training:
   CUDA_VISIBLE_DEVICES=0,1,2,3 python -m torch.distributed.launch --nproc_per_node=4 lib/main.py --cfgs ./config/gaitset_64pixel_GREW_office_split.yaml --phase train
   For testing:
   CUDA_VISIBLE_DEVICES=0,1,2,3 python -m torch.distributed.launch --nproc_per_node=4 lib/main.py --cfgs ./config/gaitset_64pixel_GREW_office_split.yaml --phase test
   In addition, you can change the config file to gaitset_64pixel_GREW_our_split.yaml to implement localization testing, as used in our paper.
2. Download the latest OpneGait source code and follow their tutorial.
