unable to build

[richardbedwell-imaginecurve]

I am unable to build an image with the dockerfile in this repo (specifically i am using the cpu version).

running the command

docker build -t sagemaker-inference-images .

ends at:

Step 20/29 : COPY lib/changehostname.c / COPY failed: stat /var/lib/docker/tmp/docker-builder354479123/lib/changehostname.c: no such file or directory

Hi @richardbedwell-imaginecurve,

Thank you for raising this issue. I believe the issue arises from the fact that the intended build context for dockerfiles in this repository is the base directory for the repo.

The base directory contains a directory named lib, with the changehostname.c file inside.

I believe running a command with the following template, once you have cloned the repository and entered its directory, should allow you to build successfully:

docker build -t <image_name>:<tag> -f docker/<PyTorch_version>/<Python_version>/Dockerfile.cpu .

For example, to build a CPU Py3 image for PyTorch 1.2.0 using the dockerfile at docker/1.2.0/py3/Dockerfile.cpu:

docker build -t preprod-pytorch:1.2.0-cpu-py3 -f docker/1.2.0/py3/Dockerfile.cpu  .

Could you please try this out and respond with the outcome?

Hi @saimidu, I'm not the OP but I tried to build the GPU version and it fails at step 36.

Step 36/40 : COPY dist/sagemaker_pytorch_container-1.2-py2.py3-none-any.whl /sagemaker_pytorch_container-1.2-py2.py3-none-any.whl
COPY failed: stat /var/lib/docker/tmp/docker-builder203823212/dist/sagemaker_pytorch_container-1.2-py2.py3-none-any.whl: no such file or directory

My build command was:

docker build -t pytorch-base:1.2.0-gpu-py3 -f docker/1.2.0/py3/Dockerfile.gpu .

I was able to build it by doing this:

cd sagemaker-pytorch-container
python setup.py bdist_wheel

Hi @domino14, Yes, that is the correct prerequisite step to be taken before the docker build is started. The build requires the sagemaker_pytorch_container-1.2-py2.py3-none-any.whl to be available in the dist/ directory in the build context.
