Unrecognized function `getCurrentJob` when running `imtool`

Open remo-pillat opened this issue 1 year ago • 1 comments

Describe the bug I recently ran all of our RVC3 book tests (running the MLX chapter files) with 24b. There was an error complaining about getCurrentJob (Parallel Computing Toolbox) not being found in chapter11.mlx.

Error snippet:

To Reproduce Run chapter11.mlx in MATLAB 24b

remo-pillat avatar Dec 02 '24 13:12 remo-pillat

This doesn't seem to be a problem in a proper MATLAB installation, but related to how tests are run through GitHub Actions. In particular, the failure occurs in parallel.internal.pool.isPoolWorker when system_dependent('isdmlworker') returns true. Note that parallel.internal.pool.isPoolWorker ships with base MATLAB, but the code path that's using getCurrentJob (only shipping in Parallel Computing Toolbox) is executed when running the unit test with the GitHub Action.

The code snippet that causes the failure in the unit test can be simplified to:

street = imread("street.png");
imtool(street)

Here are the things I tried that WORKED:

(1) Installed MATLAB 24b with all products that are indicated in RVC3 p706. Parallel Computing Toolbox is not part of that list.

  • Executed that code snippet without a problem
  • Created an MLX file with that code snippet and lightweight TestCase to run that MLX file (to emulate the MLX test in GitHub)
  • Ran test successfully with runtests

(2) Ran code snippet in MATLAB Online 24b (https://matlab.mathworks.com/)

  • Also run without a problem
  • The MATLAB Online environment has all products available (including Parallel Computing Toolbox)

Next steps: (a) Find a smaller reproduction that doesn't rely on "street.png". imtool(zeros(480,640,"uint8")) should work. (b) Verify with a GitHub Action run_command that system_dependent('isdmlworker') indeed returns true when running. (c) Create a new custom GitHub Action run_tests that only installs MATLAB + Image Processing Toolbox and still shows the same failure.

With these next steps, I should be able to further narrow down where the failure is coming from.
