I'm working on a discord bot and one of the functions I want to implement responds with text generated by the gpt-2-simple library. I want to have more then one model loaded to have multiple models available to respond to messages from my users.

However I get the following error when i run the `load_gpt2()` function in the second model 

```

    main()

```

I've tried to find a way to keep the gpt2 instances seperate between modules but i can't find anything that achieves this sandboxing effect, or any other advice for seperating the models or their instances. Does anyone have any ideas?
