Start in main.py at line 124, where the exception reports the configured checkpoint directory. Check the referenced ./out/20200424.235443 - data - ag/checkpoint path and the preceding checkpoint-reading output. Done means identifying why the expected checkpoint is not found and confirming that the reported checkpoint directory is recognized.
