How to download dynamic files created during work on Google Colab?

Question

I have two different files and on the first, I tried to save data to file as:

np.save(open(Q1_TRAINING_DATA_FILE, 'wb'), q1_data)

On second file, i'm trying to load it the same way using:

q1_data = np.load(open(Q1_TRAINING_DATA_FILE, 'rb'))

I then get the error:

FileNotFoundError: [Errno 2] No such file or directory: 'q1_train.npy'

I searched my google drive but couldn't find this file.

Platform: https://research.google.com

Edit: I'm trying to run below Kaggle problem on Colab platform. The author has two files (Jupyter and nbs) - one to prepare and 2nd to train. The step on nb1 where it's creating some files - which later to be consumed by file 2 is where I'm struck.
