How to integrate DeePMD-kit v3 with third-party packages such as ABACUS

[YuLiu98]

Summary

DeePMD-kit v2 can be integrated with third-party packages such as ABACUS according to the doc: https://github.com/deepmodeling/deepmd-kit/blob/master/doc/inference/cxx.md

DeePMD-kit v3 can also do it and can be used to run MD with *.pb models. However, it will report the following error:

terminate called after throwing an instance of 'deepmd::hpp::deepmd_exception'
  what():  DeePMD-kit C API Error: DeePMD-kit Error: PyTorch backend is not built

How to solve this problem?

DeePMD-kit Version

v3.0.0b3

Backend and its version

TensorFlow

Python Version, CUDA Version, GCC Version, LAMMPS Version, etc

No response

Details

Note that the libdeepmd_c.tar.gz of DeePMD-kit v3.0.0b3 is integrated with abacus in this issue.
It seems to lack the torch library in the lib folder:

libdeepmd_cc.so  libdeepmd_dyn_cudart.so  libdeepmd_op.so  libtensorflow_cc.so.2
libdeepmd_c.so   libdeepmd_op_cuda.so     libdeepmd.so     libtensorflow_framework.so.2

For the reasons listed in #3120 (comment), the pre-compiled package is not compiled against PyTorch.
Please tell me if you have any idea.

---

Anyway, you can compile by yourself.

Thank you. I have compile it by off-line packages. However, it reports the error:

Thank you. I have compile it by off-line packages. However, it reports the error:
