Linking error to pangolin

[loveforeverLi]

Hi,

Thanks for making this great work open source.

My compilation env: Ubuntu18.04 + cmake 3.22.1 + cuda 11.3 + Pangolin (0.6)

The compilation was done, but when linking to pangolin, the following error was reported:
[100%] Linking CXX executable bin/tandem_dataset CMakeFiles/tandem_dataset.dir/src/main_tandem_pangolin.cpp.o: In functionmain::{lambda()#1}::operator()() const':

I can compile dso successfully, so I compare the CMakeLists.txt between dso and tandem, but nothing was found. And I tried different version of pangolin, the above error reported.

I have no idea about this error, any comments will be appreciated.

solved. The libtorch abi is not compatiable with pangolin. just reinstall another abi version of libtorch
