安装到最后，Test CTC-CRF installation时出错

Test CTC-CRF installation:

可以帮忙看一下是什么原因吗

请问使用的 torch 版本是什么？

你好，torch 1.13.0+cu117

抱歉，这个问题我也没遇到过，我使用的 torch / cuda 和你是一致的。能否尝试手动重新安装

cd src/ctc_crf
python setup.py develop

然后再测试

# under src/ctc_crf
cd test
python main.py

你好，我试了试下还是不可以

可能需要重新安装libtorch，我再手动安装一下试试吧
