HOW TO TRAIN DOPE
This is the DOPE training code.
It is provided as a convenience for researchers, but it is otherwise unsupported.
Please refer to `python3 train.py --help` for specific details about the
training code.
If you download the FAT dataset
(https://research.nvidia.com/publication/2018-06_Falling-Things)
you can train a YCB object DOPE detector as follows:
```
python3 train.py --data path/to/FAT --object soup --checkpoints soup
--gpuids 0 1 2 3 4 5 6 7
```
This will create a folder called `train_soup` where the weights will be saved
after each epoch. It will use the 8 gpus using pytorch data parallel.
