@fangxu622 ,How do you solve the problem of git checkout 62ecb60?

[fangxu622]

@xingbowei 还没解决呢..运行python demo.py 也有问题l..

[xingbowei]

@fangxu622 好吧，有结果了互相帮帮忙，我也再查查

[fangxu622]

@xingbowei python demo.py 已经跑通了，这个错误好像对后面的运行没什么影响

[xingbowei]

@fangxu622 mxnet你编译了吗？

[liyi14]

just because the mxnet has change the submodule cub from NVlabs' repo to dmlc's snapshot

[xingbowei]

@fangxu622 Have you been training and testing there?

[kyeshmz]

@liyi14 So quickfix would be to change the .git/modules/cub/config to point to the NVlabs repo? What would be future fixes that could happen

@fangxu622 这个错误没影响？

[liqiang311]

@niuhaoyu16 没有影响，你可以用git submodule update || true来忽略这个错误，在某些脚本里。

[niuhaoyu16]

@liqiang311 谢谢，貌似还是不行，有时间帮忙看一下 #99

I found this error and continued to run demo.py. It runs indeed with no errors.

Dear colleagues,

Does this error in the checkout/submodule step have a final resolution? I got the headless warning on checkout, plus the error at the top of this page on the submodule update.

Thanks
