3 months ago Hi everyone. I really need help to solve this error. I have spent a lot of time on this error, and I can not solve the project without solving the error, so if anyone knows how solve it, kindly provide the answer.
Hi, I am facing the following error, while trying to simulate and generate dialogues between the user and the system:
To replicate the error, here is the code that I am using:
user_nlu = BERTNLU() user_dst = RuleDST() user_policy = RulePolicy(character='usr') user_nlg = TemplateNLG(is_user=True) user_agent = PipelineAgent(user_nlu, user_dst, user_policy, user_nlg, name='user')
sys_nlu = BERTNLU() sys_nlg = TemplateNLG(is_user=False) sys_dst = RuleDST() policy_sys = PPO(is_train=True, seed=conf['model']['seed'], vectorizer=conf['vectorizer_sys_activated']) sys_policy = PPO(is_train=True, seed=0, dataset_name='multiwoz21') sys_agent = PipelineAgent(sys_nlu, sys_dst, policy_sys, sys_nlg, name="sys")
evaluator = MultiWozEvaluator() session = BiSession(sys_agent, user_agent, kb_query=None, evaluator=evaluator) simulator = PipelineAgent(user_nlu, user_dst, user_policy, user_nlg, name='user') env = Environment(sys_nlg, simulator, sys_nlu, sys_dst, evaluator=evaluator)
def set_seed(r_seed): random.seed(r_seed) np.random.seed(r_seed) torch.manual_seed(r_seed)
set_seed(20200131)
num_dialogues = 30 dialog_data = []
sys_response = '' success_threshold = 0 success_labels = []
for i in range(num_dialogues): session.init_session() dialog = [] session_over = False cumulative_reward = 0 print(f"Turn round {i}") print() while not session_over: response = session.next_turn(sys_response) system_response, user_response, session_over, reward = response dialog.append((system_response, user_response)) cumulative_reward += reward print(f"User: {user_response}") print(f"System: {system_response}") print(f" Reward: {reward}") print() success_label = determine_success(cumulative_reward, success_threshold) dialog_data.append((dialog, success_label))
success = session.evaluator.task_success() success_labels.append(success)
Here is the full error that I am getting after running executing the code:
