GPT2 chat-bot single interaction… Attribute Error: 'NoneType' object has no attribute 'multiprocessing_chunksize' issue:2

[chkshahin]

GPT2 custom chat-bot single interaction. I am not using any thread in this implementation but still it says 'multiprocessing_chunksize'. Here we try to build chatbot using gpt2 and interact with our custom model which is trained by custom dataset(type : persona).

`#from bot_make.utils import helper import shutil from simpletransformers.conv_ai import ConvAIModel import os import pickle from termcolor import colored import requests

def cache_select(cache_name): shutil.unpack_archive('base_model/'+cache_name,'./single_interact/cache_dir','zip') print('done')

def cache_down(url): try: r = requests.get(url, allow_redirects=True) open('single_interact/cache_dir.zip', 'wb').write(r.content) shutil.unpack_archive('single_interact/cache_dir.zip','./single_interact/cache_dir','zip') os.remove(f"single_interact/cache_dir.zip") return True except: return False

#cache_select('base_model_small_cache_dir.zip') my_model = model_load('for_load.tar.gz')

#my_model.interact() os.chdir('single_interact/') a = ['hello'] def single_response(user_input): reply, history = my_model.interact_single(message=user_input, history=a) for i in history : a.append(i)

return reply

print("\n===============================================") print("================= Conv AI.V ===================") print("===============================================\n") while 1: talk = input(colored("You: ",'green')) if talk=='exit':break response = single_response(talk)

myset = set(a)
a = list(myset)
#print('Bot : ',response)
print(colored("Bot:",'red'),response)
#print('History of re : ',a)`
