@13121283123 不好意思。距离写这份代码的时间太长了，加上 pytorch_lightning 版本迭代了太多次，不太清楚如何解决这个问题。如果实在想使用，建议自行把 pytorch_lightning 的部分剥离然后写一个训练的过程。其实应该我来做这个事情的，但是最近实在是太忙，希望之后有时间能上传一份重写的代码。

@bighuang624 i followed this: https://www.kaggle.com/kirichenko17roman/dsanet-approach#New-confirmed-cases-prediction
using the last version of pytorch_lightning return the error of this issue but with 0.7.3 its working.

also the kaggle version use the a gpu version so im wondering if you release also the .py for the gpu because im having an hard time using their code, i dont understand all the conversion from dataframe to np array for the training data and how to get test the model at the end
