                Hi, I figured this one out; leaving a small note if you stumble on this issue yourself. All you need to do is add tokenizer_config.json file with additional configs for the tokenizer. I added a simple tokenizer_config.json with the following contents: 
{“model_max_length”: 512} 
That’s all. 
Cheers, …
