Error when using attention_memory_training equal to 0

RLlib Configure Algorithm, Training, Evaluation, Scaling
1

When I set a model with the following config:

model: { _disable_preprocessor_api: false,
use_attention: true,
attention_num_heads: 8,
attention_memory_inference: 0,
attention_memory_training: 0,}

I get the following error:
