invalid device ordinal

[gingerhead22]

Error happened when I tried to run train_lsp.sh file, it said cuda error or invalid device: invalid device ordinal

I use Cygwin on windows 10. GPU is GTX 1070, and both cuda and cudnn works well.

Do I need 2 GPU to run alexnet?

Thank you very much.

I'm having the same problem, have you found a solution?

[ThorJonsson]

You can try to reset the 'gpus' number in the sh file pertaining to the dataset you're training on. This file is in the 'bash' folder.

Thank you for your suggestion. Yep, I reset my gpus as 0 and problem solved. However, there are more problem with pickle() command happened then.

@gingerhead22 Hi,I want to ask, if I just have one GPU GTX 1070 , 'gpus' number is '0' or '1'? I don't what is my GPU number. I didn't find the explain of 'gpus number'.

@ShaoNeilz Hey, u should set it as 0, since the ordinal starts from 0

@gingerhead22 thanks for your answer!
May I ask one another question ?
When I run 'train_flic.sh' , I haven't gotten any extention about the trainning, and system will be halted.
here is my terminal's context. This makes me really confused.
OS: ubuntu 14.04 amd_64;python 2.7.x;
