Can't run simple_pose.py

[anoop54]

OSError: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by ./posenet_lib/x86_64/posenet_decoder.so)

Any idea on this?

I compiled my own posenet_decoder as well, which results in a different error. Is this .so only working with ubuntu 20?

That seems like your OS doesn't meet the required GLIBC version for required for that so file. You can check with:

ldd --version

It needs to be 2.29 or above

[anoop54]

Yeah, mine is 2.27, seems like I'll need to update from Ubuntu 18. Can you explain to me why the version I built does not work? I no longer get the GLIBC error, but get the following when using:

Code import tflite_runtime.interpreter as tflite posenet=tflite.load_delegate('./posenet_lib/x86_64/posenet_decoder.so') interpreter = tflite.Interpreter(model_path='posenet_mobilenet_v1_075_481_641_quant_decoder.tflite',experimental_delegates=[posenet]) interpreter.allocate_tensors()

Output: return self._interpreter.AllocateTensors() RuntimeError: Encountered unresolved custom op: edgetpu-custom-op.Node number 0 (edgetpu-custom-op) failed to prepare.

I build the posenet_decoder.so using the edgetpu repo and the commands you gave here: https://github.com/google-coral/edgetpu/issues/127#issuecomment-636036478

Also the version that gets built is 2.2mb where as the one in the repo is like 200kb.

@anoop54 well there are 2 libraries that needs to be loaded. Yo built your own lib and it actually works, but now you're having problem with libedgetpu LOL

For libedgetpu, though, it's not as complicated, I think you just have an older version that isn't compatible with the current tflite_runtime package. Try this:

sudo apt install libedgetpu1-std

Hi @Namburger

I tried to run the simple_pose.py on ubuntu 18.04. I installed pycoral_api, tf_runtime, and libedgetpu. when I execute the simple_pose.py, I got the error message like below.

/lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by ./posenet_lib/x86_64/posenet_decoder.so)

    if self._library is not None:
AttributeError: 'Delegate' object has no attribute '_library'

I wonder this project is available to run for only ubuntu 19 or higher version?

@drimyus this is the same issue, you are going to have to build libedgetpu.so that matches your glibc, unfortunately

[drimyus]

@Namburger Thank you for your response, btw can you let me know where I can check the guide to build the libedgetpu.so?

Former version of simple_pose.py could work on raspberry pi OS. But now, newest version of raspberry pi OS have GLIBC 2.28, so current simple_pose.py can't work on any raspberry pi. We need simple_pose.py which can work on raspberry pi OS. Would you give me any good idea?

[Namburger]

@Yaskoga this is an issue with the OS, not an RPI, I think one think you can do is to upgrade glibc on the pi or recompile the armv7 binary with a lower glibc

Thanks for your reply. I installed UBUNTU 20.10 desktop which has GLIBC 2.32 to my raspberry pi4. And I tried install posenet. I succeeded to work simple_pose.py.

It seems issue was resolved. Feel free to reopen if still exists.
