Let's first run an unconditional sample:

#@title Step 11: Generating Unconditional Samples
import os # import after runtime is restarted
os.chdir("/content/gpt-2/src")
!python generate_unconditional_samples.py --model_name '117M'

You will not be prompted to enter context sentences since this is an unconditional sample generator.

To stop the cell, double-click on the run button of the cell or type Ctrl + M.
