We think it may be caused by the machine having too little memory, we tried using your code but did not reproduce the problem. You can try it by shortening the training data, or you can try a different machine with more memory.
I 'm running 1min data ,the script as below, swap mem is 128G, It will be killed by OOM, why? start time:2020-09-14 end_time: 2021-06-21
and all.txt contains 4067 stocks. I attached all.txt at the end. I downloaded these 1min data from yahoo by: python scripts/get_data.py qlib_data --target_dir ~/.qlib/qlib_data/cn_data_1min --region cn --interval 1min
I used 8 kernels
how should I configure?
