+READ FIRST BEFORE MAKING CHANGES
+-  Create a convention for resources created from vertex-ai-samples GH. We already have one IIRC
+- Only delete those objects as part of our clean-up script.
+- Don't run any tests on python-docs-samples-tests project, especially ones that affect resources created outside of our purview
+- Add --dry-run option to the clean-up script. This option will just output the list of resources the script will delete instead of actually deleting the resources.
+- Have a larger conversation in DEE before touching any resources that were not created as part of vertex-ai-samples

+The VCN inference algorithm is as follows:
+1. Find all video frames within the given clip according to the sampling FPS.
+2. Create possibly overlapping sliding windows according to the num_frames and
+overlap_frames parameters. The last window might have a larger overlap if it
+doesn't exactly fit.
+3. Run model inference on each sliding window and compute softmax to obtain
+probabilities.
+4. Average the probabilities over all sliding windows.
+
+The VAR inference algorithm is very similar to VCN, with a few differences:
+1. The last sliding window is discarded if it does not exactly fit.
+2. Instead of averaging, the postprocessing consists of temporal nonmaximal
+suppression and removing background and low-confidence labels.
