undefined symbol: _ZN12carotene_o4t during import mediapipe in raspberry pi 3 #2056

Closed superuser789 closed 3 years ago

superuser789 commented 3 years ago

I am trying to build mediapipe for Raspberry Pi 3 on RPi3 itself. I built the latest opencv release 4.5.2 by following these guide

and successfully built opencv with these flags cmake -D CMAKE_BUILD_TYPE=RELEASE \ -D CMAKE_INSTALL_PREFIX=/usr \ -D OPENCV_EXTRA_MODULES_PATH=/home/pi/opencv/opencv_contrib-4.5.2/modules \ -D ENABLE_NEON=ON \ -D ENABLE_VFPV3=ON \ -D BUILD_TESTS=OFF \ -D INSTALL_PYTHON_EXAMPLES=OFF \ -D OPENCV_ENABLE_NONFREE=ON \ -D CMAKE_SHARED_LINKER_FLAGS=-latomic \ -D BUILD_EXAMPLES=OFF ..

To build mediapipe, I used bazel binary and prebuilt opencv 4.5.2. Followed official guide, made the changes in opencv_linux.BUILD & ffmpeg_linux.BUILD using 

sed -i "s/x86_64-linux-gnu/arm-linux-gnueabihf/g" third_party/opencv_linux.BUILD
sed -i "s/x86_64-linux-gnu/arm-linux-gnueabihf/g" third_party/ffmpeg_linux.BUILD

and also commented "include/opencv2/**/*.h*", & uncommented "include/opencv4/opencv2/**/*.h*", under hdrs and commented "include/", & uncommented "include/opencv4/", under includes in opencv_linux.BUILD.

To resolve _ZN3ruy14Kernel8bitNeon issue. I added :

        '--copt=-march=armv7-a',
        '--copt=-mfpu=neon-vfpv3',

as told by arron2003 here.

Built the package : python3 setup.py gen_protos && python3 setup.py bdist_wheel & Installed using : sudo python3 -m pip install mediapipe-0.8-cp37-cp37m-linux_aarch64.whl --no-deps

But during import mediapipe I get this error :

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.7/dist-packages/mediapipe/__init__.py", line 16, in <module>

Checking with nm -gCD /usr/local/lib/python3.7/dist-packages/mediapipe/python/_framework_bindings.cpython-37m-arm-linux-gnueabihf.so | grep -n rgb2hsv gives :

I even tried to build opencv without custom hal carotene by changing ON to OFF in this line. But still throws the same undefined symbol: _ZN12carotene_o4t7r error. Which program or library is causing this issue ?

Please guide me to resolve this issue. Thanks.

I disabled carotene_o4t when I built mediapipe python on aarch64 ubuntu. See the step 6 of https://github.com/jiuqiant/mediapipe_python_aarch64#readme.

Hi @superuser789, Please check the above comment.

hhajae commented 3 years ago

I have a Raspberrypi4 with Raspbian os. After import mediapipe as mp mp.solutions.hands in python3.7.3,

"module 'mediapipe' has no attribute 'solutions'".

I'm looking for the solution.

  1. file name = module name? --> My file name isn't same any module names.
  2. When I compared my desktop with Rpi, I found that there was another mediapipe folder in the mediapipe folder of the pie. So I wrote "from mediapipe import mediapipe" in init.py in the first mediapipe folder, and ran. An error occurred in "from mediapipe.python import *" in init.py in python module. It was that there was no "_framework_binding" module. Even though I have 'framework_binding.cc' in mediapipe/mediapipe/python.

So I found '_frameworkbinding~~.so' in mediapipe/python in mediapipe_python_aarch64/mediapipe-0.8.1-cp38-cp38-linux_aarch64.whl in https://github.com/jiuqiant/mediapipe_python_aarch64 but when I ran, I received error "ELFCLASS64".

Can't I use mediapipe in Python in Raspian? Should I install Ubuntu?

Please help. thank you. @jiuqiant @sgowroji

I think, the most appropriate option to disable carotene_o4t is to add "WITH_CAROTENE": "OFF", in third_party/BUILD. After adding "WITH_CAROTENE": "OFF",, the ImportError was gone.

I have written all the steps here https://github.com/superuser789/MediaPipe-on-RaspberryPi#readme .

I think following steps 5&6 of https://github.com/jiuqiant/mediapipe_python_aarch64#readme, gives "module 'mediapipe' has no attribute 'solutions'" error. I rebuilt my mediapipe package without removing any OpenCV modules and did not face any error. I have written my steps here https://github.com/superuser789/MediaPipe-on-RaspberryPi#readme .
