I don't use Docker. If it is so mandatory, recommend me an image :)

Docker is not necessary. But it is helpful to setup the environment. I guess the problem you encounter is you don't install the MPI, or the make file cannot find the MPI successfully.

We have recommend some docker images in the guides of different models. You can choose one by your requirement.

Thank you. I'll try to run it in the docker.

ok, your driver and gpu are both too old to use the docker. Try to build the repo in your previous environment, but add -DBUILD_MULTI_GPU=OFF.

@byshiue I need a gpt-j inference with two tesla k80s. Is this even possible?
I have tried so many things. Nowhere works because the Tesla K80 is too old.

You can try the suggestion in this issue #69.

Besides, you can try to add -lmpi into CMakeLists.txt of gptj_example.

I had the same problem in a non-docker environment too. Adding mpi_cxx to the link dependency of mpi_utils solved it.

Got the same problem, I installed openmpi==4.0.2 from anaconda
