Torch-Scope
A Toolkit for training pytorch models, which has three features:
- Tracking environments, dependency, implementations and checkpoints;
- Providing a logger wrapper with two handlers (to
stdandfile); - Supporting automatic device selection;
- Providing a tensorboard wrapper;
- Providing a spreadsheet writer to automatically summarizing notes and results;
We are in an early-release beta. Expect some adventures and rough edges.
Quick Links
Installation
To install via pypi:
pip install torch-scope
To build from source:
pip install git+https://github.com/LiyuanLucasLiu/Torch-Scope
or
git clone https://github.com/LiyuanLucasLiu/Torch-Scope.git
cd Torch-Scope
python setup.py install
Usage
An example is provided as below, please read the doc for a detailed api explaination.
- set up the git in the server & add all source file to the git
- use tensorboard to track the model stats (tensorboard --logdir PATH/log/ --port ####)
from torch_scope import wrapper
...
logger = logging.getLogger(__name__)
if __name__ == '__main__':
parser = argparse.ArgumentParser()
parser.add_argument('--checkpoint_path', type=str, ...)

...
args = parser.parse_args()
pw = wrapper(os.path.join(args.checkpoint_path, args.name), name = args.log_dir, enable_git_track = False)
# Or if the current folder is binded with git, you can turn on the git tracking as below
# pw = wrapper(os.path.join(args.checkpoint_path, args.name), name = args.log_dir, enable_git_track = True)
# if you properly set the path to credential_path and want to use spreadsheet writer, turn on sheet tracking as below
# pw = wrapper(os.path.join(args.checkpoint_path, args.name), name = args.log_dir, \

device = torch.device("cuda:" + str(gpu_index) if gpu_index >= 0 else "cpu")
pw.save_configue(args) # dump the config to config.json
# if the spreadsheet writer is enabled, you can add a description about the current model
# pw.add_description(args.description)
logger.info(str(args)) # would be plotted to std & file if level is 'info' or lower
