ERROR: Unknown command: pair_styled deepmd

[Coldwater-fish]

I installed deepmd-kit via offline package deepmd-kit-2.1.5-cpu-Linux-x86_64.sh. When I run deepmd-kit/bin/lmp using a trained model, it leads to the following error:

ERROR: Unknown command: pair_styled deepmd graph-compress.pb (src/input.cpp:274)
Last command: pair_styled deepmd graph-compress.pb

I also tried the deepmd-kit-2.1.1-cpu version, and the same error occurred.
And when execute lmp -h , there is no deepmd under Pair styles.
(I have done it : source /path/to/deepmd-kit/bin/activate /path/to/deepmd-kit)

How to solve this problem? Thanks a lot!

Also tried conda activate /path/to/deepmd-kit. It still does't work.

The correct command is pair_style instead of pair_styled. You can refer to LAMMPS documentation - pair_style command is not provided by us.

Hello. I am having a similar problem. ERROR: Unrecognized pair style 'deepmd' (src/force.cpp:279). I used conda install lammps cudatoolkit=11.6 horovod -c https://conda.deepmodeling.com to install the lammps. I used conda activate deepmd to activate my deepmd env before I ran lmp -i in.lammps. So I think I've followed all the necessary steps. Do you know what could be the problem? Thank you so much!

Yes I did. I can find it in conda list. libdeepmd 2.0.3 0_cuda11.3_gpu https://conda.deepmodeling.com I also have libdeepmd_lmp.so and libdeepmd_lmp_low.so in deepmd/lib. deepmd is the name of my conda env.

2.0.3 does not match the latest lammps. You need to upgrade it to the latest version.

Thanks for the reply. What's the latest version of libdeepmd? I tried conda update libdeepmd still got 2.0.3

BTW, I am running GPU version of deepmd

The latest version is 2.1.5
