+# Usage
+Create a virtual environment using the `requirements.txt` file:
+```
+virtualenv -p python3 venv
+source venv/bin/activate
+pip install -r learning_embeddings/requirements_3.6.txt
+pip install opencv-python
+pip install gitpython
+```  
+
+Use branch `Adam1x` to run experiments with the ETHEC dataset:  
+`git checkout Adam1x`  
+
+Splits for the ETHEC dataset can be found in `splits` folder. Experiments in this repository were conducted using **v0.1** of the ETHEC dataset.  
+
+Sample command:  
+`python learning_embeddings/network/ethec_experiments.py --experiment_name exp_test --experiment_dir exp --image_dir ETHEC_dataset_v0.1/ETHEC_dataset/IMAGO_build_test_resized/ --n_epochs 1 --model resnet18 --loss multi_level --set_mode train`
