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).
