How to run the benchmarks

1. Download datasets and put them in the following directory structure:
2. Clone this repository.
3. Run the run.sh script that will build a Docker image and train models using the following command:

./run.sh </path/to/data/directory> </path/to/outputs/directory>

e.g. ./run.sh ~/data ~/outputs

where

• </path/to/data/directory> is a path to a directory that contains datasets (e.g., a directory that contains folders imagenet, pascal_voc, etc)
• </path/to/outputs/directory> is a path to a directory that should contain outputs from a training pipeline, such as a CSV log with metrics and a checkpoint with the best model.
