Issue importing mediapipe on Raspberry Pi

[assman]

Hi Jiuqiang

I followed the instructions and was successfully able to install mediapipe. When I run

ls /home/pi/.local/lib/python3.7/site-packages/mediapipe/python, the solutions folder is present.

However, when I run the interactive python3 shell from my root directory and do a import mediapipe as mp, I get an error as such

Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/pi/.local/lib/python3.7/site-packages/mediapipe/__init__.py", line 16, in <module> from mediapipe.python import * File "/home/pi/.local/lib/python3.7/site-packages/mediapipe/python/__init__.py", line 17, in <module> from mediapipe.python._framework_bindings import resource_util ImportError: /home/pi/.local/lib/python3.7/site-packages/mediapipe/python/_framework_bindings.cpython-37m-arm-linux-gnueabihf.so: undefined symbol: __atomic_load_8

I'm experiencing the same problem but for the symbol "_ZN3ruy14Kernel8bitNeonERKNS_16KernelParams8bitILi4ELi2EEE"

That's strange. I wonder what could be the issue that's causing this. Which OS are you on? I'm on raspbian.

I'm also on Raspbian (or Raspberry Pi OS what it's called now). I found the same issue on the mediapipe repository (https://github.com/google/mediapipe/issues/1346). My issue is related to Tensorflow. Your symbol however is one of the first in the binary. You can check with nm -gCD /home/pi/.local/lib/python3.7/site-packages/mediapipe/python/_framework_bindings.cpython-37m-arm-linux-gnueabihf.so | grep -n "__atomic_load_8". Maybe your issue is related to cmake? I'm not sure.

Ok I will check it out thank you

Oh I had this problem with atomic, too, and found that building Bazel using the guide and scripts in here, then coming back and running the mediapipe installation fixed it.
