Err: only integer scalar arrays can be converted to a scalar index!

[LiuZhihhxx]

I received an error message "only integer scalar arrays can be converted to a scalar index"(following picture) but not clear what it means.

I tried to dubug on my local machine by establishing an environment like "Backend Files for Evaluation"(https://github.com/PaddlePaddle/PaddleSpatial/tree/main/apps/wpf_baseline_gru/kddcup22-sdwpf-evaluation)

However another error occured:

I've got it through that it's because NUM_MAX_RUNS = 196 (defalt setting in evaluation.py) but only 1 pair of "test_x" and "test_y" in the environment. And when I set NUM_MAX_RUNS = 1 and ignored the std error(line 273-278 in evaluation.py), everything went well and it yielded final MAE, RMSE, and Final Score.

I'm confused that:
(1) What lead to the first error?
(2) Why different errors occured online and locally?
(3) To locally debug, is it necessary to prepare 196 pairs of test_x and test_y in the local environment?

Any help will be appreciated.
