@lunalulu it expects some env variables to be set, to successfully import, here is the snippet that solves the import issue.

conda activate oneposeplus
cd $CONDA_PREFIX
mkdir -p ./etc/conda/activate.d
mkdir -p ./etc/conda/deactivate.d
touch ./etc/conda/activate.d/env_vars.sh
touch ./etc/conda/deactivate.d/env_vars.sh

Edit ./etc/conda/activate.d/env_vars.sh as

#!/bin/sh
export TORCH_USE_RTLD_GLOBAL=YES
export OLD_PYTHONPATH=$PYTHONPATH
export PYTHONPATH=$PYTHONPATH:${REPO_ROOT}/submodules/DeepLM/build

Edit ./etc/conda/deactivate.d/env_vars.sh as

#!/bin/sh
unset TORCH_USE_RTLD_GLOBAL
export PYTHONPATH=$OLD_PYTHONPATH
unset OLD_PYTHONPATH

Hi @lunalulu ans @krishna-esrlabs, I'm facing a similar issue except when i get the error ModuleNotFoundError: No module named 'BACore' The terminal looks like this:

I tried what you have said @krishna-esrlabs, but I get the same error...

-- The CUDA compiler identification is unknown
CMake Error at /home/linux/miniconda3/envs/oppp/lib/python3.8/site-packages/cmake/data/share/cmake-3.25/Modules/CMakeDetermineCUDACompiler.cmake:603 (message):
Failed to detect a default CUDA architecture.

Your compilation failed because of this reason. Either the Cuda compiler is missing or the CMake is unable to find it. Check nvcc --version, if it is there add the cuda path so that CMake can find it.
