Sanity-test failed with WSLg

[BravoFr0st]

Sanity-test failed

SMARTS version：0.4.18

Operating System：Ubuntu 18.04 LTS on WSL2(Windows 11)
WSLg has enabled

Problems
After make sanity-test, all tests passed EXCEPT test_smarts_doesnt_leak_tasks_after_reset

 A renderer is required to test smarts_doesnt_leak_tasks_after_reset. You may not have installed the [camera-obs] dependencies required to render the camera sensor observations. Install them first using the command `pip install -e .[camera-obs]` at the source directory.

However, my WSL has already enabled WSLg , and other program (such as sumo) can open a GUI.

After that I try to run scl scenario build --clean scenarios/loop and scl run --envision examples/single_agent.py scenarios/loop and
no error occurs.

Hello @BravoFr0st , thank you for reaching out. I believe it is promising that sumo-gui is working so I am going to take a look into WSLg compatibility.

Otherwise, the rest of SMARTS will work even without rendering until you have need to use image based observations. Envision will still work since it is rendered through the browser.

Thanks a lot.

@BravoFr0st I have put up some improved tests. If you have the time could you do the following:

git checkout tucker/bugfix-wslg_rendering_failure
scl scneario build --clean scenarios/loop
pytest -vv --renderer-debug-mode info smarts/core/tests/test_renderers.py::test_optional_renderer

It would help greatly towards solving the issue.

I have also enabled some rendering fallbacks on the wslg bug branch so it is also possible the test may pass.

Hello, I had the same issue with the sanity-test. Since the other person didn't reply, I'm just letting you know that I ran the commands you listed and the test passed. Hope it helps.
