I think the reason is your ram is not enough, I used a desktop with 32g ram, and it works fine. I think there are 2 ways: 1) change to another computer 2) modify the code to stream read the data.

There are too many unique characters(6000+) in qun_tang_shi.txt. I delete it to 4000+, then it works for me.

@hx364 By the way, there are some errors in your repository because of carelessness.

1. Missing 'return model' in the definition of function train_model
2. Forget to define 'char_to_index' and 'index_to_char' as global names, which will be used in function 'make_poem_index'. Define them outside the main function or pass it to function 'make_poem_index' as a parameter.
