hey help when runnig the first sample test

[cyrstem]

▶ python jukebox/sample.py --model=5b_lyrics --name=sample_5b --levels=3 --sample_length_in_seconds=20 --total_sample_length_in_seconds=180 --sr=44100 --n_samples=6 --hop_fraction=0.5,0.5,0.125

i get this error

Make sure the model fully downloaded from GCE to ~/.cache/jukebox_assets/.

Yes, sometimes the download fails silently (we used quiet flag in wget so it doesnt show you an error), causing the restoring of the checkpoint to fail. You'll need to redownload.
