nvblox_torch in conda env: installation fails [Solved] #6

Closed sjauhri closed 4 months ago

How are you using nvblox_torch (docker/native/conda/?): conda, PRECXX11_ABI

Issue Details: When installing nvblox_torch (after successfully installing nvblox with PRECXX11_ABI), I get the following Cmake error when running the install sh install.sh $(python -c 'import torch.utils; print(torch.utils.cmake_prefix_path)'):

CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: LIBNVTOOLSEXT linked by target "py_nvblox" in directory /home/sjauhri/IAS_WS/isaac/ov/pkg/nvblox_torch/src/nvblox_torch/cpp

Seems like it can't link to libnvToolsExt? It does correctly find CUDA because it first outputs: -- Caffe2: CUDA detected: 11.8 -- Caffe2: CUDA nvcc is: /home/sjauhri/miniconda3/envs/isaac-sim-2023-try/bin/nvcc -- Caffe2: CUDA toolkit directory: /home/sjauhri/miniconda3/envs/isaac-sim-2023-try -- Caffe2: Header version is: 11.8 -- /home/sjauhri/miniconda3/envs/isaac-sim-2023-try/lib/libnvrtc.so shorthash is c993a6f1 -- USE_CUDNN is set to 0. Compiling without cuDNN support -- Autodetected CUDA architecture(s): 8.6 -- Added CUDA NVCC flags for: -gencode;arch=compute_86,code=sm_86

Also, libnvtoolsext.so exists in my conda env path at /lib//libnvToolsExt.so

Is the path for libnvToolsExt.so in $LD_LIBRARY_PATH ?

Thanks for the hint. Modifying the LD_LIBRARY_PATH did not change anything but changing PATH did. Fixed this issue by explicitly adding the 'lib' directory where libnvToolsExt.so exists to PATH: export PATH=/home/sjauhri/miniconda3/envs/isaac-sim-2023-new/lib:$PATH
