when I run main_crnn.py I court this issue:
#error -- unsupported GNU version! gcc versions later than 6 are not supported!

Now,I work it out! just uninstall all the cuda ,cudnn,gcc .cmake
reinstall cuda(it contains cudnn,gcc,cmake)

Instead of uninstalling/reinstalling gcc, I found this more useful.

I have tried this solution on colab but still not working!!

!pwd
%cd /content
!git clone -b pytorch_bindings https://github.com/SeanNaren/warp-ctc.git
%cd /content/warp-ctc
!mkdir build
%cd /content/warp-ctc/build
#!cmake ..
!cmake -D CMAKE_C_COMPILER:string=gcc-5 -D CMAKE_CXX_COMPILER=g++-5 ../
!make
