ZeroDivisionError: division by zero

I use my dataset，the text is short，but the shape is 10240, maybe where I should change?

The denominator is ZERO. Maybe u can set a proper batch size and small max_seq_length. Moreover, using cross-validation maybe another option.

the test acc is always about 60%,but the train is more than 90%,I do not konw why?

[jxy-001]

maybe test need some operate?

ur data will be divided into 70% train set and 30% test set. If ur data set is small, the result is basically wrong. All u can do is setting a proper proportion about set and test set.
