ValueError: Key img_path is not in available keys.
2024/06/05 15:33:54 INFO mlflow.system_metrics.system_metrics_monitor: Stopping system metrics monitoring...
2024/06/05 15:33:54 INFO mlflow.system_metrics.system_metrics_monitor: Successfully terminated system metrics monitoring!

I hit this bug when I run a pipeline which is almost identical to the example in configs/

mmcv==2.1.0
mmdeploy==1.3.1
mmdet==3.3.0
mmengine==0.10.4
albumentations==1.4.8

The actual error message is coming from albumentations' Compose class, not MMDetection.

Would be great if a version of albumentations was specified with https://github.com/open-mmlab/mmdetection/tree/cfd5d3a985b0249de009b67d04f37263e11cdf3d/configs/albu_example

Thanks so much, that was super helpful! I found that I needed a feature released after 1.3.1 though, and it turns out that the issue seems to have been introduced in 1.4.7, so any version below that should work.

@Theelx thanks so much to you too. Looks like I now need that feature! Was just hitting a mysterious bug, and thought I'd try this. Working perfectly.

There's also this fix for empty images that it took me a bit too long to discover.

Oh thanks lol, I never noticed that! I had been working around that by just setting a single pixel per class on the image in the corners, so that every mask had at least one pixel of every class, but this seems way better!

Also, I believe 1.4.11 could work too if strict=False was passed to albumentations.Compose, as specified in the Core section of the 1.4.11 release notes, though I haven't tried it yet.

Ok, I can confirm that passing strict=False to mmsegmentation's codebase's initialization of albumentations.Compose results in it working with mmdeploy, so I'd think the same would happen with mmdetection.

@Theelx
Fix albu versions >= 1.4.11 (open-mmlab#11770)
79e35f8 
This commit introduces very basic version parsing for albumentations in order to know whether the strict parameter for albu.Compose is supported, and passes strict=False if it is. If it isn't supported, fall back to not passing the strict parameter, which only works on albu <= 1.4.6.
