i have meet the same problem, and i have use this repo for a long time, but it occur today

A few days ago, I had no problem. Today, I suddenly appeared. I found a lot of solutions, but I couldn't solve them

[zhangfengyo]

yes, why it occur?

[zhangfengyo]

i am curious. i use the warp-ctc for hundreds times, but it occur before i submit the project to my boss.

[zhangfengyo]

did you run it on colab? maybe some update is done by google

[Luna-yu]

I changed the GCC version because there was an error in the next make step. After that, cmake made an error

Yes I have tried it on colab, it through below error

i change warpCTC to pytorch ctc module, there is just a bit to be changed, and the output was great too.

maybe you can find a repo using pytorch'CTC, maybe what you should do is just adding a softmax function.
