The required packages can be found in config/env_files/traffic_sign_recognition_env.yml. Dependencies could be installed by running:
conda env create -f config/env_files/traffic_sign_recognition_env.yml
The experiments are run according to configurations. The config files for those can be found in config/config_files. Configurations can be based on each other. This way the code will use the parameters of the specified base config and only the newly specified parameters will be overwritten.
The base config file is base.yaml. A hpo example can be found in base_hpo.yaml which is based on base.yaml and does hyperparameter optimization only on the specified parameters. An example for test based on base.yaml can be found in test.yaml.
The code should be run with arguments:
--id_tag specifies the name under the config where the results will be saved
--config specifies the config name to use (eg. config "base" for config/config_files/base.yaml)
--mode can be 'train', 'val', 'test' or 'hpo'
The required data's path should be specified inside the config file like:
data:
params:
dataset_path: '/home/data/R-jpg' \
During train, val and hpo the files should be under their class subdirectory (eg. /home/data/R-jpg/stop_table).
During test the files should all be in the specified directory.
The save folder for the experiment outputs can be set in the config file like:
id: "base"
env:
result_dir: 'results'
All the experiment will be saved under the given results dir: {result_dir}/{config_id}/{id_tag arg}
- tensorboard files
- train and val metric csv
- the best model
- confusion matrices and by class metrics
If the result dir already exists and contains a model file then the experiment will automatically resume (either resume the training or use the trained model for inference.)
To train the model use:
python run.py --config base --mode train
For eval the results dir ({result_dir}/{config_id}/{id_tag arg}) should contain a model as model_best.pth.tar. During eval the validation files will be inferenced and the metrics will be calculated.
python run.py --config base --mode val
For test the results dir ({result_dir}/{config_id}/{id_tag arg}) should contain a model as
model_best.pth.tar. During test the predictions will be saved along with the filepaths in a csv file.
A pretrained model can be found in here.
For simplicity it is recommended to copy it under results/base/base and just change the dataset path to yours in config/config_files/test.yaml.
python run.py --config test --mode test
For hpo use:
python run.py --config base_hpo --mode hpo
HPO result:
Confusion matrix:
By class F1 score:
