Please edit the documentation for the sections How to train and Inference

Correct commands:
How to train
python3 main.py --model_path='save_models' --experiment='english' --epochs=70 --batch_size=75 --training=True

Inference should be
python3 main.py --model_path='save_models' --experiment='english' --training=False (there is an additional space after the "=" which was removed)
