【问题描述】

在鲲鹏环境（openEuler 20.03 LTS SP3）编译wenet 2.0.1报undefined reference to `at::_ops::zeros::call(c10:ArrayRef<long>, c10::optional<c10::ScalarType>, c10::optional<c10::Layout>, c10::optional<c10::Device>, c10::optional<bool>)'和undefined reference to `at::_ops::cat::call(c10::ArrayRef<at::Tensor>, long)'错误，详细报错信息如下：

【解决方法】

手动下载获取libtorch-shared-with-deps-1.13.0%2Bcpu.zip解压并替换../fc_base/路径下的libtorch-src文件夹

cd ../fc_base/

wget cid:link_0

rm -rf libtorch-src

mv libtorch libtorch-src

然后再次执行cmake --build .编译。
