ADD:
I download http://www.webpagepublicity.com/free-fonts/x/Xerox%20Sans%20Serif%20Narrow%20Bold.ttf to mxnet/data/Xerox.ttf , and then run the command.Mxnet is build with CUDA enabled.

Have you build baidu-warpctc and include warpctc plugin?

[piiswrong]

This maybe relevent baidu-research/warp-ctc#40

[xylcbd]

mxnet is built with baidu-warpctc , and the warpctc library is loaded success.

YES , it is built with CUDA 8.0. And I will try the solution of baidu-research/warp-ctc#40. thx!
