Dear,
I have run several tests on similar dataset usps, and no error occurred.
Could you please provide more details or zip your dataset and put it here if available?
Make sure that your dataset is in a LibSVM format.
Thanks.

亲爱的，
我在类似的数据集usps上运行了几次测试，没有发生错误。
您能否提供更多详细信息或压缩您的数据集并将其放在此处（如果有）？
确保您的数据集采用LibSVM格式。
谢谢。
hello,this is my dataset:
1.txt

waiting for your advice,thanks!

Hi there,
We found that your dataset is zero_based (the first index of feature is 0).
The newest version is able to handle zero_based dataset.
You can use the newest code or turn your dataset into one-based.
Thanks.

hello,Running the original code after changing my dataset succeeded.but i use the newest code,This has a new problem.
my thundergbm-train:

my dataset is always 1.txt,

i use the newest code,When my dataset is 1.txt running thundergbm-predict file succeeds, but when the dataset is 2.txt thundergbm-predict file fails ,this is a new problem

my dataset is 2.txt,2.txt file size is 1.43GB,I don't know if it is because the file is too big.

It should work.
You should check your dataset, or share it through the cloud (Baidu Yun?)

this my dataset(Baidu Yun):

thank you very much!

hello ,thank you very much for your help.
but my Configuration is:
max_depth=6 num_round=40 n_gpus=1 verbosity=0 profiling=0 data=C:\Users\Administrator\Desktop\2\2.txt max_bin=255 colsample=1 bagging=1 num_parallel_tree=1 eta=1.0 objective=multi:softmax num_class=8 min_child_weight=1 lambda=1 gamma=1 tree_method=auto
when building thundergbm-train is ok,
when building thundergbm-predict is failed.

Yes, the same configuration as yours.
I ran the test via command line, editing the machine.conf. It works fine for me.

@lvpinrui

thank you very much for your help these days.
I tried it a few times or not, I succeeded after changing my dataset.

Since the issue is solved, I will close it.
