Repo Build Failed on `ObjectDetectionTest` and `TfSsdTest` using Codespaces due to the lost package `fontconfig`. #2256

Closed Noricks closed 1 year ago

Noricks commented 1 year ago

Description

Hi, when I try to build the repo using the provided Codespaces environment, the following two tests FAILED:

  1. ai.djl.examples.inference.ObjectDetectionTest
  2. ai.djl.tensorflow.integration.modality.cv.TfSsdTest

The problem originated from java.desktop/sun.awt.X11FontManager.

It could be solved by adding the package fontconfig to the Codespaces Dockerfile or it can be skipped using TestRequirments.

The problem may have some relationship with the OpenJDK Dockerfile problem: https://gitlab.alpinelinux.org/alpine/aports/-/issues/7372

I am more than happy to submit a pull request if this approach is acceptable.

Expected Behavior

The tests should PASS or SKIP.

How to Reproduce?

Environment

Open the repo in the Codespaces, which will use the Docker environment provided along with DJL repo.

It is worth noting that the 8GB memory might not be sufficient to execute some of the tests.

Steps to reproduce

Single Command

Dedicated Commands

What have you tried to solve it?

Approaches that DO work

Approach 1: Install package fontconfig in the provided Dockerfile (.devcontainer/Dockerfile)

RUN apt-get update && export DEBIAN_FRONTEND=noninteractive \
     && apt-get -y install --no-install-recommends fontconfig

Approach 2: SKIP the tests using TestRequirments

Add the following lines in the TestRequirments:

    /** Requires that the test runs on a machine with a display. */
    public static void display() {
        if (System.getenv("DISPLAY") == null) {
            throw new SkipException("This test requires a display.");
        }
    }

Approaches that do not work

  1. Run with headless -Djava.awt.headless=true
  2. unset DISPLAY

@Noricks Thanks so much for your investigation. I think we should do both.

Please go ahead and create a PR to address this issue.
