[Jeffwan]

em. I notice it's a simple change and file path are all correct.

@tenzen-y

training-operator/examples/pytorch/cpu-demo/Dockerfile

Line 7 in 6133600

COPY demo.py .

seems it copy files from current folder instead of the root folder. using examples/pytorch/cpu-demo/demo.py should resolve the issues. Let's cut a separate PR to fix it..

I guess that we need to specify context like this:

training-operator/.github/workflows/publish-example-images.yaml

Line 45 in 6133600

context: examples/xgboost/xgboost-dist

[Jeffwan]

@tenzen-y Yeah, changing the context works as well.

@tenzen-y Yeah, changing the context works as well.

I would change the context later. BTW, it seems that this PR has been merged automatically, should I pull a new one? @tenzen-y @Jeffwan
