The second input argument "agentBlk" must be a block path to a valid "RL Agent" block.

When I try to define environment for walking robot, I receive this error:

>> SACAgentForWalkingRobot

Error using rlSimulinkEnv (line 113)

The second input argument "agentBlk" must be a block path to a valid "RL Agent" block.

Error in SACAgentForWalkingRobot (line 16)

env = rlSimulinkEnv(mdl, blk, observationInfo, actionInfo);

This error is inside rlSimulinkEnv and it cannot validate RL Agent blocks.

I try to change Walking Robot -- DDPG Agent Training Script (2D) to SAC Agent Training.

Hi mustafa,

The error indicates that the input to the agentBlocks argument (path to the RL Agent block in the model) in the rlSimulinkEnv function is not correct. Can you share the code and model you are using?
