I try to load a saved SAC model but the model load have a problem like this.

Model generation;

model = SAC(‘MultiInputPolicy’, vec_env, gamma=best_params[‘gamma’], learning_rate=best_params[‘learning_rate’], buffer_size=best_params[‘buffer_size’], batch_size=best_params[‘batch_size’], ent_coef=”auto_0.1″, policy_kwargs=policy_kwargs, verbose=1, tensorboard_log=tensorboard_log_dir+”TRY_2_”)

model.save(location)

model.load(location)
