Raspberry PI 4 64 Bit OS beta, Coral USB accelerator, classify_capture.py libmmal.so error
hackebike opened this issue · comments
I am testing Google Coral TPU usb accelerator on a Raspberry PI 4 64 Bit OS beta, Kernel 5.10.
I am getting this error when I run the classify_capture.py script:
python classify_capture.py
Traceback (most recent call last):
File "classify_capture.py", line 24, in <module>
import picamera
File "/usr/local/lib/python3.7/dist-packages/picamera/__init__.py", line 72, in <module>

import picamera.mmal as mmal

_lib = ct.CDLL('libmmal.so')

self._handle = _dlopen(self._name, mode)
OSError: libmmal.so: cannot open shared object file: No such file or directory
Am I suppose to install the library? From where?
Edit: maybe I need to wait as they fix it
@hackebike that's a library that the pi OS is missing LOL
I know, but they had the package and libs and then they took it out. I am playing guessing game!
thx for the support, other examples worked. I will update when they fix the issue.
closing as the issue is a Raspberry PI OS issue.
