Install DALI from source got error "file format not recognized" and "syntax error"

[NaufalRezkyA]

Describe the question.

Hi, I tried to install DALI from source but got an error while building it. Any Suggestions? Thank you.
Machine: Ubuntu20.04, CUDA 11.2, Docker 24.0.7

Command that I used:

git clone https://github.com/NVIDIA/DALI.git
git submodule sync --recursive
git submodule update --init --recursive
sudo ./build.sh

Error while install the DALI:

Hi @NaufalRezkyA,

Thank you for reporting this. This is an unfortunate implicit dependency of cv-cuda. Before cloning the DALI repo please install git lfs, as some cv-cuda source code artifacts are stored using this approach.

Hi @JanuszL , thanks it works now after i installed git lfs and clone the repository again.

But, how to access the system after the installation is finished?
I tried to access the image like this, but there is no dali or cuda in the image (i also tried tag cu123_x86_64.deps, cuda123_x86_64.toolkit, x86_64.deps ):

cc@naufal-gpufs-dali2-rtx:~$ docker container run -it nvidia/dali:cu123_x86_64.build /bin/bash

Hi @NaufalRezkyA,

By default, the build process mounts your DALI source code directory inside the container. The build artifacts should be placed inside build-docker-* if that is what you are looking for.
