# Runtime Warnings & Errors Analysis
|
||
|
||
Pipeline: `python launcher.py --config configs/simbox/de_plan_and_render_template.yaml`
|
||
Environment: IS 5.0.0, RTX PRO 6000 Blackwell, conda `banana500`
|
||
Date: 2026-04-03

|
||
## Errors
|
||
|
||
### 1. PhysicsUSD: triangle mesh collision on dynamic body
|
||
|
||
```
|
||
[Error] PhysicsUSD: Parse collision - triangle mesh collision (approximation None/MeshSimplification)
|
||
cannot be a part of a dynamic body, falling back to convexHull approximation:
|
||
/World/task_0/split_aloha/.../lifting_link/collisions
|
||
```
|
||
|
||
**Severity:** Medium (PhysX auto-fallback, but logs error every reset)
|
||
**Root cause:** Robot USD `lifting_link/collisions` mesh 使用 `meshSimplification` 碰撞近似，PhysX 不支持动态物体使用 triangle mesh collision。
|
||
**Fix:** 修改 robot USD 将 `MeshCollisionAPI.approximation` 从 `meshSimplification` 改为 `convexHull`。
|
||
|
||
```python
|
||
from pxr import Usd, UsdPhysics
|
||
stage = Usd.Stage.Open('workflows/simbox/example_assets/split_aloha_mid_360/robot.usd')
|
||
prim = stage.GetPrimAtPath('/Root/.../lifting_link/collisions')
|
||
UsdPhysics.MeshCollisionAPI(prim).GetApproximationAttr().Set('convexHull')
|
||
stage.GetRootLayer().Save()
|
||
```
|
||
|
||
**Status:** FIXED. Backup: `robot.usd.bak`
|
||
|
||

|
||
|
||
### 2. Physics scenes stepping mismatch
|
||
|
||
```
|
||
[Error] Physics scenes stepping is not the same, step subscription will be send with later step,
|
||
per scene step is not yet supported.
|
||
```
|
||
|
||
**Severity:** Low (仅首次 reset 时出现一次)
|
||
**Root cause:** IS 5.0.0 内部 physics scene 步进调度问题。physics_dt 和 rendering_dt 均为 1/30，配置一致。
|
||
**Status:** IGNORED. IS 内部行为，不影响仿真结果。
|
||
|
||
---
|
||
|
||
## Warnings — Fixed
|
||
|
||
### 3. Camera aperture inconsistent with resolution
|
||
|
||
```
|
||
[Warning] 'verticalAperture' (1.529) and 'horizontalAperture' (2.095) are inconsistent with
|
||
the pixel resolution aspect ratio (1.333). Setting 'verticalAperture' to 1.572 to ensure square pixels.
|
||
```
|
||
|
||
**Severity:** Low (IS 自动修正，但每个相机打 2 条 warning)
|
||
**Root cause:** `custom_camera.py` 在 `self.initialize()` 之后才设置 aperture/focal_length，但 `initialize()` 时就用默认 aperture 做一致性检查。
|
||
**Fix:** 重构 `custom_camera.py`，将 aperture/focal_length 设置移到 `initialize()` 之前。
|
||
|
||
```python
|
||
# Before (wrong order):
|
||
super().__init__(...)
|
||
self.initialize() # <-- checks aperture here with default values
|
||
# ... later ...
|
||
self.set_horizontal_aperture(...) # too late, warning already printed
|
||
|
||
# After (correct order):
|
||
super().__init__(...)
|
||
self.set_horizontal_aperture(...) # set aperture first
|
||
self.set_vertical_aperture(...)
|
||
self.set_focal_length(...)
|
||
self.initialize() # now checks with correct values
|
||
```
|
||
|
||
**Status:** FIXED in `workflows/simbox/core/cameras/custom_camera.py`
|
||
|
||
---
|
||
|
||
### 4. Camera.set_projection_type deprecated
|
||
|
||
```
|
||
[Warning] Camera.set_projection_type is deprecated and will be removed in a future release.
|
||
Please use Camera.set_lens_distortion_model instead.
|
||
```
|
||
|
||
**Severity:** Low
|
||
**Fix:** 替换 API 调用，带 fallback 兼容旧版本。
|
||
|
||
```python
|
||
# Before:
|
||
self.set_projection_type("pinhole")
|
||
# After:
|
||
try:
|
||
self.set_lens_distortion_model("pinhole")
|
||
except AttributeError:
|
||
self.set_projection_type("pinhole")
|
||
```
|
||
|
||
**Status:** FIXED in `workflows/simbox/core/cameras/custom_camera.py`
|
||
|
||

|
||
|
||
## Warnings — Requires Manual Action
|
||
|
||
### 5. CPU powersave mode
|
||
|
||
```
|
||
[Warning] CPU performance profile is set to powersave. This profile sets the CPU to the
|
||
lowest frequency reducing performance.
|
||
```
|
||
|
||
**Severity:** Medium (影响整体性能)
|
||
**Fix:** 需要 sudo 权限手动设置。
|
||
|
||
```bash
|
||
# 临时切换到 performance 模式 (重启后恢复)
|
||
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
|
||
|
||
# 永久设置 (Ubuntu)
|
||
sudo apt install cpufrequtils
|
||
echo 'GOVERNOR="performance"' | sudo tee /etc/default/cpufrequtils
|
||
sudo systemctl restart cpufrequtils
|
||
```
|
||
|
||
**Status:** MANUAL. 需要用户自行设置。
|
||

|
||
|
||
## Warnings — Ignored (Safe)
|
||
|
||
### 6. IS 5.0 API deprecation warnings (~100 条)
|
||
|
||
```
|
||
[Warning] omni.isaac.core has been deprecated in favor of isaacsim.core.api.
|
||
Please update your code accordingly.
|
||
```
|
||
|
||
**Severity:** None
|
||
**说明:** IS 5.0 对所有 `omni.isaac.*` 模块重命名为 `isaacsim.*`。旧 API 仍然可用，仅打印 deprecation 提示。不影响功能，无需修改。如果将来升级到 IS 6.x 可能需要迁移。
|
||

|
||
|
||
### 7. Curobo warp cache warnings
|
||
|
||
```
|
||
[Warning] [curobo] Object already in warp cache, using existing instance for:
|
||
/World/task_0/pick_object_left/Aligned/mesh
|
||
```
|
||
|
||
**Severity:** None
|
||
**说明:** Curobo 内部 warp kernel 缓存机制。同一 mesh 在多次 world update 中被重复加载时复用缓存。完全正常，无害。
|
||
|
||
---
|
||
|
||
### 8. Robot dummy_base inertia tensor warnings
|
||
|
||
```
|
||
[Warning] The rigid body at .../dummy_base_rotate has a possibly invalid inertia tensor of
|
||
{1.0, 1.0, 1.0} and a negative mass, small sphere approximated inertia was used.
|
||
```
|
||
|
||
**Severity:** None
|
||
**说明:** Robot USD 中 `dummy_base_rotate/x/y` 是虚拟关节（用于全局位移），不需要真实质量属性。PhysX 自动使用球体近似惯性张量，功能正常。
|
||
|
||
---
|
||
|
||
### 9. Table mesh corrupted normal primvar
|
||
|
||
```
|
||
[Warning] Mesh '/World/task_0/table/Instance/Group_default_00/SM_08_component6_0' has corrupted
|
||
data in primvar 'normal': buffer size 14880 doesn't match expected size 2482
|
||
```
|
||
|
||
**Severity:** Low
|
||
**说明:** Table USD 中一个子网格的 normal 数据大小不匹配。IS 会忽略损坏的 normal 并自动计算。不影响渲染和物理。如需修复，需在 DCC 工具（Blender/Maya）中重新导出 table USD。
|
||
|

|
||
|
||
### 10. GPU / Hardware warnings
|
||
|
||
```
|
||
[Warning] Skipping unsupported non-NVIDIA GPU: AMD Ryzen 7 9800X3D (RADV RAPHAEL_MENDOCINO)
|
||
[Warning] ECC is enabled on physical device 0
|
||
[Warning] IOMMU is enabled.
|
||
```
|
||
|
||
**Severity:** None
|
||
**说明:** 系统有 AMD 集显（跳过正常）。RTX PRO 6000 默认开启 ECC（牺牲约 6% 显存带宽换数据可靠性）。IOMMU 已启用。均为信息提示。
|
||
|
||

|
||
|
||
### 11. SdRenderVarPtr missing LdrColorSDhost
|
||
|
||
```
|
||
[Warning] SdRenderVarPtr missing valid input renderVar LdrColorSDhost
|
||
```
|
||
|
||
**Severity:** None
|
||
**说明:** Synthetic data pipeline 中 LDR color 渲染变量在 headless 模式下首帧未就绪。后续帧正常。不影响输出。
|
||
|
||
---
|
||
|
||
### 12. trimesh sampling warning
|
||
|
||
```
|
||
[Warning] [trimesh] only got 3/4 samples!
|
||
```
|
||
|
||
**Severity:** Low
|
||
**说明:** Grasp pose 采样时某个物体只获得 3 个（期望 4 个）抓取采样点。不影响功能，pipeline 会使用获得的采样继续运行。
