Answer questions jiuqiant

Because you use the wrong binary.

In docs/solutions/hands.md, we mention that

With Multi-hand Support
Running on CPU
Graph: mediapipe/graphs/hand_tracking/multi_hand_tracking_desktop_live.pbtxt
Target: mediapipe/examples/desktop/multi_hand_tracking:multi_hand_tracking_cpu

Please do

bazel-bin/mediapipe/examples/desktop/multi_hand_tracking/multi_hand_tracking_cpu \
  --calculator_graph_config_file=mediapipe/graphs/hand_tracking/multi_hand_tracking_desktop_live.pbtxt

useful!
