hi, I also appear this problem when train a new model. But I can't solve this problem. Could you help to introduce the details about this problem? So mach thanks.

I've come across the same problem and solved it by compiling MXNet@(commit 62ecb60). Here are some notes from my experience:

• MXNet@(commit 62ecb60) uses submodule cub from https://github.com/NVlabs/cub, instead of https://github.com/dmlc/cub for later versions. I had trouble fetching cub@89de7ab with a git error: Server does not allow request for unadvertised object or reference is not a tree. It seems that the commit 89de7ab of cub is no longer reachable, probably caused by a force push. As a workaround, I clone the cub repo at https://github.com/NVlabs/cub manually and checkout to branch 1.6.4 with command git checkout 1.6.4. It works.
• MXNet@(commit 62ecb60) does not have psroi_pooling operator implemented, so you should copy the operator source files together with channel_operator in README 3.4. That is, do cp -r $(FCIS_ROOT)/fcis/operator_cxx/* $(MXNET_ROOT)/src/operator/contrib/.

Hope these will be helpful!
