From 9242498970f57573702ccf75fcce6980288439a1 Mon Sep 17 00:00:00 2001 From: jichuanh Date: Wed, 20 May 2026 23:11:54 +0000 Subject: [PATCH 01/40] [CI] Add Windows + ARM pytest markers and shared scaffolding Foundation for cross-platform CI. Registers four pytest markers (windows, windows_ci, arm, arm_ci), teaches AppLauncher to recognize them in argv so they do not leak into Isaac Sim's argparse, and moves the AssetConverterBase USD scratch directory from a hardcoded /tmp/IsaacLab to tempfile.gettempdir() for cross-platform compatibility. Tags source/isaaclab/test/deps/test_torch.py and test_scipy.py with the new markers so they are selectable by future cross-platform jobs.

Why: 1. Single venv create + single isaacsim install shared across all test steps. Saves ~5 venv setups (~3 min each = ~15 min wall). 2. The runner gets ONE allocation, stays continuously busy, never sees an inter-job idle gap. Autoscaler can't tear it down and strand queued siblings (the cancellation cascade we kept hitting). 3. Same affinity guarantee as Linux/ARM single-job model — every test step touches the same runner's filesystem and Sim install. Each test step has continue-on-error: true and writes its own JUnit XML. A final aggregate step parses outcomes and fails the job iff any non-perception step failed. perception is gated as 'warning, not failure' until the runner pool fixes TCC->WDDM, so the workflow doesn't lie about overall status while still surfacing the failure clearly. --- .github/workflows/windows-ci.yaml | 602 ++++++++++-------------------- 1 file changed, 190 insertions(+), 412 deletions(-) diff --git a/.github/workflows/windows-ci.yaml b/.github/workflows/windows-ci.yaml index fa428e3b22c6..fef683697b58 100644 --- a/.github/workflows/windows-ci.yaml +++ b/.github/workflows/windows-ci.yaml @@ -4,16 +4,25 @@ # SPDX-License-Identifier: BSD-3-Clause # Windows CI — exercises Isaac Lab on Windows GPU self-hosted runners. -# Same shape as arm-ci.yaml but the install path is native pip + uv on the -# host (no Docker on Windows for Linux-based Isaac Sim wheels). -# Tier 1 (smoke + install): general-windows, install-windows, kit-launch-windows -# Tier 2 (meaningful, marker-filtered): path-io-windows, perception-windows +# Single consolidated job to dodge runner-pool autoscaler idle-down (which +# would tear the runner between multiple smaller jobs and starve any queued +# siblings; observed repeatedly in the per-tier split). +# Same coverage as the previous per-tier layout: +# deps smoke (general) -> path-IO tests -> Kit headless boot -> +# cartpole training smoke (state rsl_rl + perception rl_games) -> +# perception smoke (cartpole RGB-Camera, needs Vulkan/WDDM) -> +# wheel build + reinstall. +# Setup chain (uv venv, editable installs, isaacsim, Sim path resolution) is +# done once and shared.

On bare-metal Windows, NVIDIA's data-center driver does not expose graphics APIs (OpenGL/Vulkan/DirectX) for these SKUs regardless of TCC vs WDDM driver mode; per the Data Center GPU driver release notes, vGPU is required to expose them. Kit's boot path reflects this exactly: vkEnumeratePhysicalDevices returns no devices, gpu.foundation logs "TCC is not supported. GPU(s) should be in WDDM mode.", and Kit then hangs in omni.gpu_foundation_factory until the OS-level watchdog fires. Comment out the perception step (preserve verbatim for restoration), drop the now-dangling perception_smoke.py artifact path and the steps.test-perception.outcome reference in the Aggregate step, and note in the file header that perception is disabled. The disabled-step context block lists the three independent unblock criteria (vGPU on L40S, swap runner SKU, or move perception coverage to Linux) so the next maintainer can pick whichever lands first. --- .github/workflows/windows-ci.yaml | 147 +++++++++++++++++------------- 1 file changed, 86 insertions(+), 61 deletions(-) diff --git a/.github/workflows/windows-ci.yaml b/.github/workflows/windows-ci.yaml index fef683697b58..644152a03db9 100644 --- a/.github/workflows/windows-ci.yaml +++ b/.github/workflows/windows-ci.yaml @@ -7,16 +7,16 @@ # Single consolidated job to dodge runner-pool autoscaler idle-down (which # would tear the runner between multiple smaller jobs and starve any queued # siblings; observed repeatedly in the per-tier split). -# Same coverage as the previous per-tier layout: +# Active coverage: # deps smoke (general) -> path-IO tests -> Kit headless boot -> # cartpole training smoke (state rsl_rl + perception rl_games) -> -# perception smoke (cartpole RGB-Camera, needs Vulkan/WDDM) -> # wheel build + reinstall. +# The Cartpole-RGB-Camera perception smoke is commented out below; see the +# disabled-step context block for the reason and the unblock criterion. # Setup chain (uv venv, editable installs, isaacsim, Sim path resolution) is # done once and shared.

The new order mirrors install.py (_install_isaacsim() then _ensure_cuda_torch()). * Install `source/isaaclab_newton` with `--no-deps`. cartpole_env_cfg.py imports `isaaclab_newton.physics` at module load, so every cartpole task fails with `ModuleNotFoundError: No module named 'isaaclab_newton'` without it. Same `--no-deps` reason as isaaclab_physx (both declare a bare-name dep on isaaclab_ppisp that's not yet on this branch nor on any index; the ppisp import is lazy at runtime). The smoke-import line is extended so this regression fails fast in setup, not in a later test step. * Replace the em-dash in the Aggregate step's `Write-Host "::error::"` with an ASCII hyphen. PowerShell 5.1 reads the temp .ps1 as cp1252, so the 3-byte UTF-8 em-dash mis-decodes inside the string and the closing quote is mis-detected, raising "The string is missing the terminator". The path was never executed before because `$failed` was always empty (only perception had failed, and it was excluded from the gating set). --- .github/workflows/windows-ci.yaml | 34 +++++++++++++++++++------------ 1 file changed, 21 insertions(+), 13 deletions(-) diff --git a/.github/workflows/windows-ci.yaml b/.github/workflows/windows-ci.yaml index 644152a03db9..af97d07d8b6b 100644 --- a/.github/workflows/windows-ci.yaml +++ b/.github/workflows/windows-ci.yaml @@ -168,30 +168,38 @@ jobs: uv venv --python 3.12 --seed env_isaaclab_uv & "env_isaaclab_uv\Scripts\Activate.ps1" uv pip install -e source/isaaclab - # isaaclab_physx is a runtime dep of isaaclab_tasks (the - # GroundPlaneCfg.physics_material forwarding shim imports it eagerly - # when isaaclab_tasks is walked at import time). --no-deps because - # isaaclab-physx==1.1.0 declares a hard dep on isaaclab-ppisp, - # which is not on any index nor in source/.

On Windows, h5py's libhdf5 keeps an internal handle to the file briefly after `.close()`, so `rmtree` races with the handle release and raises `PermissionError [WinError 32]` on teardown of `test_write_and_load_episode[cuda:0]`. The assertions had already passed; only the cleanup was failing. Switch to `tempfile.TemporaryDirectory(ignore_cleanup_errors=True)` (Python 3.10+). On Linux/macOS this flag is a no-op since no cleanup error is raised; on Windows it absorbs the libhdf5 handle-release race without masking real failures (the test body still asserts via the explicit `dataset_file_handler.close()` calls).

The hand-rolled sequence had grown three latent issues, all of which the canonical install.py path avoids: * Install order — `_install_isaacsim()` runs before `_ensure_cuda_torch()` inside install.py, so isaacsim's transitive CPU torch can't shadow the cu128 wheel. The previous hand-rolled order had the cu128 upgrade first and broke `[cuda:0]`-parametrized tests. * Missing isaaclab_newton — install.py walks CORE_ISAACLAB_SUBMODULES, so isaaclab_newton is installed automatically. cartpole_env_cfg.py's import of `isaaclab_newton.physics` no longer fails. * No more --no-deps workarounds — with `source/isaaclab_ppisp/` present the renderer-backend bare-name dep resolves through the local editable install. The workflow keeps the test-only `pytest pytest-timeout h5py` install (install.py doesn't carry pytest plumbing) and the post-install smoke import. Setup-step body shrinks from ~25 lines to ~3 substantive lines. Matches the "Mirror Linux CI setup for new platforms" rule: same entry point as Linux CI (`./isaaclab.sh -i`), so install-order bugs and new core submodules are picked up automatically when install.py changes. --- .github/workflows/windows-ci.yaml | 64 +++++++++++++------------------ 1 file changed, 26 insertions(+), 38 deletions(-) diff --git a/.github/workflows/windows-ci.yaml b/.github/workflows/windows-ci.yaml index af97d07d8b6b..5d770d564aea 100644 --- a/.github/workflows/windows-ci.yaml +++ b/.github/workflows/windows-ci.yaml @@ -152,54 +152,42 @@ jobs: # uv installs into $HOME\.local\bin on Windows; add to PATH for next steps.

Move the ctypes Vulkan loader probe out of the workflow into a standalone tools/vulkan_probe.py: * Loads vulkan-1.dll / libvulkan.so.1 via ctypes. * Calls vkCreateInstance + vkEnumeratePhysicalDevices. * Reports loader-load, instance-create, and physical-device count. * No dependencies beyond the OS Vulkan loader; cross-platform. The workflow now invokes it with system Python on the runner. Probe moves to the first runnable step (right after instance-state report) so diagnostic data appears in ~30 seconds instead of after the 15-min isaaclab.bat -i install. All other test steps gated off (`if: false`) for now while we iterate; aggregate gates the job purely on the probe's outcome.

Windows therefore tested a different, older Sim than the rest of the matrix. Resolve the develop-aligned build from the internal Artifactory index and pin it, verifying the build's commit is on omni_isaac_sim develop when a gitlab token is available and falling back to the newest 6.0.0 build with a warning otherwise. Install Isaac Sim from that index, then install IsaacLab without the isaacsim/all extras that would re-pin the public release. Add tools/resolve_isaacsim_develop.py and its unit tests.
