Hi everyone, I've been trying to figure out what is this error is about since there is no reference of the object/node where this happens. For me it only happens when I'm training my Reinforcement Learning agent, on each episode of training excluding the first episode. When I'm running the model manually it runs perfectly. I don't know why it happens, as I tried changing the modeling on my process flow.
Attached is my model as well as the python script to train the Agent.
The model's logic is simple. It is a remanufacturing line composed of 2 stages, Inspection and Disassembly. The agent decision is to decided which operator does the next task. The observation is done as soon as the item is available.
I would really appreciate your help in this issue. I've spent too many hours on it.
