Hi,

I did your tutorial 3 times, but I keep getting the same error:

Traceback (most recent call last): File "Object_detection_picamera.py", line 23, in import cv2 File "/usr/local/lib/python3.7/dist-packages/cv2/init.py", line 3, in from .cv2 import * ImportError: /usr/local/lib/python3.7/dist-packages/cv2/cv2.cpython-37m-arm-linux-gnueabihf.so: undefined symbol: __atomic_fetch_add_8

Did I do something wrong?

Thanks!

No same for me, but I found out you can use LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libatomic.so.1 python3 Object_detection_picamera.py

But then I got this here: 2020-04-13 14:03:06.554427: E tensorflow/core/platform/hadoop/hadoop_file_system.cc:132] HadoopFileSystem load error: libhdfs.so: cannot open shared object file: No such file or directory WARNING:tensorflow:From /home/pi/tensorflow1/models/research/object_detection/utils/label_map_util.py:138: The name tf.gfile.GFile is deprecated.

hi g2721, I am facing the same problem.Did you find any solution for this error? Thank you.

@lavanya5 Yeah i got it working. I guess you are running it on the console ? For me installing Pixel (the gui for raspberrys or the complete Gui) worked

[g2721]

Just look for install x server on pi and type startX or so to activate the gui
