Closed nnzhan closed 5 years ago

nnzhan commented 5 years ago

Could you please help me fix the error. When I run 

python -m scripts.generate_training_data --output_dir=data/METR-LA

I get the following logs

I think this is a problem caused by the division syntax of the Python 2.7 version. You can run this code in Python 3.5.
