在构建warp-ctc-pytorch时收到一个生成错误

Question

我正在尝试构建https://github.com/SeanNaren/warp-ctc.git在谷歌Colab上，关注这个笔记本。我在Colab:上使用这些命令

!git clone https://github.com/SeanNaren/warp-ctc.git;
cd warp-ctc;
mkdir build;
cd build;
cmake ..;
make;

但我收到了一个构建错误：

[-11%] Building NVCC (Device) object CMakeFiles/warpctc.dir/src/warpctc_generated_ctc_entrypoint.cu.o

如何解决这一问题？

Answer 1

这篇文章记录了这个问题的明显修复，它也影响了原始的warp-ctc存储库：

[…]ctc_entrypoint.cu文件需要是符号链接。因此，转到src-dir并运行：

rm ctc_entrypoint.cu
ln -s ctc_entrypoint.cpp ctc_entrypoint.cu

然后，重新运行make，这将解决问题。
