I have installed pytorch_ctc，but got the import error.

from pytorch_ctc import CTCBeamDecoder as CTCBD
Traceback (most recent call last):

Can you tell me what compiler is used and which version of libstdc++?

[bliunlpr]

I used CC=/usr/bin/gcc-5 CXX=/usr/bin/g++-5 python setup.py install.
I have no idea which version of libstdc++. How can I check this ? Thanks!

I got a similar error but then I rebuilt using sudo and it worked. Not very insightful but give it a shot if you've not already done so.

I think the recent build changes should solve this.
