Error in Building the Docker Container

[pramitd]

Hi, Thank you for the codebase. I am trying to run the model (https://github.com/isl-org/lang-seg) which requires torch-encoding. For my research I need to build a singularity container from a docker image and add any further dependencies to the singularity.

Currently, to ensure that I have correct environment I decided to compile the docker provided here and then convert it to the singularity.

When running bash scripts/build_docker.sh , I get the following error:

ninja: build stopped: subcommand failed. Traceback (most recent call last): File "/opt/conda/lib/python3.6/site-packages/torch/utils/cpp_extension.py", line 1471, in _run_ninja_build check=True) File "/opt/conda/lib/python3.6/subprocess.py", line 438, in run output=stdout, stderr=stderr) subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

During handling of the above exception, another exception occurred: Traceback (most recent call last): File "setup.py", line 125, in cmdclass={"build_ext": torch.utils.cpp_extension.BuildExtension}, File "/opt/conda/lib/python3.6/site-packages/setuptools/init.py", line 161, in setup return distutils.core.setup(**attrs) File "/opt/conda/lib/python3.6/distutils/core.py", line 148, in setup dist.run_commands() File "/opt/conda/lib/python3.6/distutils/dist.py", line 955, in run_commands self.run_command(cmd) File "/opt/conda/lib/python3.6/distutils/dist.py", line 974, in run_command cmd_obj.run() File "/opt/conda/lib/python3.6/site-packages/setuptools/command/develop.py", line 38, in run self.install_for_development() File "/opt/conda/lib/python3.6/site-packages/setuptools/command/develop.py", line 140, in install_for_development self.run_command('build_ext') File "/opt/conda/lib/python3.6/distutils/cmd.py", line 313, in run_command self.distribution.run_command(command) File "/opt/conda/lib/python3.6/distutils/dist.py", line 974, in run_command cmd_obj.run() File "/opt/conda/lib/python3.6/site-packages/setuptools/command/build_ext.py", line 87, in run _build_ext.run(self) File "/opt/conda/lib/python3.6/site-packages/Cython/Distutils/old_build_ext.py", line 186, in run _build_ext.build_ext.run(self) File "/opt/conda/lib/python3.6/distutils/command/build_ext.py", line 339, in run self.build_extensions() File "/opt/conda/lib/python3.6/site-packages/torch/utils/cpp_extension.py", line 633, in build_extensions build_ext.build_extensions(self) File "/opt/conda/lib/python3.6/site-packages/Cython/Distutils/old_build_ext.py", line 194, in build_extensions self.build_extension(ext) File "/opt/conda/lib/python3.6/site-packages/setuptools/command/build_ext.py", line 208, in build_extension _build_ext.build_extension(self, ext) File "/opt/conda/lib/python3.6/distutils/command/build_ext.py", line 533, in build_extension depends=ext.depends) File "/opt/conda/lib/python3.6/site-packages/torch/utils/cpp_extension.py", line 462, in unix_wrap_ninja_compile with_cuda=with_cuda) File "/opt/conda/lib/python3.6/site-packages/torch/utils/cpp_extension.py", line 1211, in _write_ninja_file_and_compile_objects error_prefix='Error compiling objects for extension') File "/opt/conda/lib/python3.6/site-packages/torch/utils/cpp_extension.py", line 1484, in _run_ninja_build raise RuntimeError(message) RuntimeError: Error compiling objects for extension

Any clue as to what am I missing here. Should I have some library on my system to build the docker ? I am stuck on this issue for more than a week!

Looking forward to your reply. Best Regards, Pramit

I have the same exact issue on docker as well, also coming here from lang-seg to try to get it to work. I've also tried regular pip install but "import encoding" would always generate an error. Hope this gets attention soon!

Is the docker in torch-encoding working? https://hangzhang.org/PyTorch-Encoding/notes/compile.html#using-docker

[zhanghang1989]

For issue related to lang-seg, it would be great to reach out to the original authors

Hi, Error posted above is coming during building the docker file in this repository and not lang-seg.

In my case, I solve this error by running the docker container using a command (not use run_docker.sh) and installing torch-encoding.

docker run -it -d -P --gpus all --name encoding nvcr.io/nvidia/pytorch:20.06-py3
docker exec -it encoding bash
pip install torch-encoding

Also, this error can occur when you use pip install git+https://github.com/zhanghang1989/PyTorch-Encoding/. So you should use pip install torch-encoding instead.
