I'm ready to help you craft a response to the issue with running Coral USB on the ES. While I can't directly access or execute code, I'll provide a comprehensive response based on the information you've shared and my knowledge of common troubleshooting steps.

Here's a structured response, addressing key points and potential solutions:

"I understand you're encountering a segmentation fault when attempting to run the Coral USB on the ES. Let's work together to troubleshoot this issue."

"From the logs you've provided, here are the key points I've gathered:"
The segmentation fault occurs when loading the "TPU object detection" model.
Pycoral examples are working successfully, indicating the Edge TPU is functional.

Verify Model Compatibility:
"Ensure that the ssdlite_mobiledet_coco_qat_postprocess_edgetpu.tflite model is specifically compiled for Edge TPUs. You can check compatibility using the edgetpu_compiler tool."
Check Model File Integrity:
"Re-download or re-compile the model to rule out corruption. Verify its integrity using the edgetpu_compiler tool."
Experiment with Different Models:
"Try using a different Edge TPU-compatible model to isolate whether the issue is model-specific or related to the environment."
Inspect Memory Usage:
"Monitor memory usage during model loading. If memory is exhausted, consider reducing model size or allocating more memory."
Investigate Permissions:
"Ensure the www-data user has the necessary permissions to access the model file and Edge TPU device."

"To provide more specific guidance, please share the following details:"
Complete model configuration in /etc/zm/objectconfig.ini
Full output of edgetpu_compiler when checking model compatibility
Additional error messages or logs
Specifications of your ES system (OS version, hardware configuration)

Resources for Troubleshooting:

ZoneMinder Documentation: The official ZoneMinder documentation offers troubleshooting guides and community forums: https://zoneminder.readthedocs.io/
Coral Edge TPU Support: If you're using a Coral Edge TPU device, refer to the Coral documentation for troubleshooting model loading issues: https://coral.ai/docs/accelerator/get-started/voojio
YoloV4 Documentation: If you're using the YoloV4 model specifically, check the Yolo project documentation for potential error messages: https://github.com/topics/yolov4 /ome gle

"I'm ready to assist with further troubleshooting steps as needed. Please provide any additional information, and I'll do my best to help you resolve this issue."
Stay engaged and offer tailored guidance based on the user's responses and findings.

Is www-data able to talk to the coral? Could be permissions

yes, iv try as root too...

iv find a suitable solution for me:

Installed Python3.9 with Pyenv and changed in the Pythonscripts

#!/usr/bin/python3 to #!/usr/local/bin/python3.9

installed all required packages with pip3.9 and it works

for facedetection Pillow < 10.0.0. Pillow > 10 not work.
