Having a terrible time with the raspi related problems. One of them concerning the libcamera. I have Ubuntu 22.04 64bit on my raspi and I have installed the libcamera package with the command sudo apt install libcamera_*. The problem is that whenever I run a command with libcamera it tells me command not found!!! Any solutions?!! The camera is detected and supported. Thanks in advance for your help.
Any one came across this problem?

After few hours spending on this, it turns out to be the Erlang was too old. Upgraded it to latest version Erlang/OTP 23, problem solved!
the problem cause by incompatible between RabbitMQ and Erlang/OTP:
Ubuntu 18.04 provides Erlang 20.2 and RabbitMQ 3.8.14 requires 22.3 or 23.x. See RabbitMQ and Erlang/OTP Compatibility Matrix
Installing latest Erlang version should solve the problem.
$sudo apt-get install erlang
The problem commonly happens when only upgrade rabbitMq without Erlang. (as my case: rabbitMq 3.8.0 -> 3.8.14)
I am using rasa 1.9.6 on ubuntu in Vmware I have been getting this error in both training as well as running the model. It allows training the model but I am unable to run it I need to run my Bot can someone please help
According to rasa forum, the origin of this issue is due to tensorflow and graphics card configuration. GPU’s do not typically provide an advantage for the Rasa models. This can be safely ignored
Installing nvidia-modprobe can solve this issue.
sudo apt install nvidia-modprobe
Other solutions you can try are :
Uninstall and install CUDA and cuDNN.
Install tensorflow-gpu.
Uninstall and install different Nvidia driver versions.
The problem also could be that only some /dev/nvidia* files are present before running Python with sudo, check using $ ls /dev/nvidia*, after running the Device Node verification script the /dev/nvidia-uvm file gets added.
I've been following the tutorial at https://learn.microsoft.com/en-us/azure/iot-edge/tutorial-python-module
On my development machine, the python lint in Visual Studio Code is reporting the error: E0401:Unable to import 'iothub_client' on main.py.
I wonder if I'm missing a pre-requisite step, or is this just an advisory that can be ignored on the development side of things and it should be ok once deployed - or do I need to fix this error on the development machine first?
I've successfully run the previous tutorial and have tempSensor running. filterSensor seems to terminate and go into a "backoff" state once deployed, with an error of 1. I don't know how I can find out on the Edge-side why it is failing - how do I go about debugging this? Can I see print statement output anywhere, for example?
I'm developing on Mac, and deploying to a Beaglebone running Ubuntu 16.04 LTS.
For the Python lint issue, yes you are right that this information is just advisory. The cause for it showing up is that you did not install Azure IoT Python SDK which is a pip package on your development machine. You can safely ignore it because the SDK will be installed when building the module image (there is a RUN pip install -r requirements.txt step in the Dockerfile).
If you want to resolve this lint information, you can install the SDK on your development machine manually by running pip install -r requirements.txt in the root folder of the module.
I am using Titanium SDK Version 6.0.0
So I have been able to install the project onto a 'NextBook' running Android 4.4.2
But when I try and deploy it to an S2 with 4.1.2 I get the following error
Failed to install apk on "001938f563f26e"
Error: Unknown option: -d
I am using usb debugging
the device has 1.7 GB of free space
Has anyone seen this error before ?
Thank for helping
In the manifest section of your tiapp.xml what do you have set for android:minSdkVersion? Should be 16 or higher to target that device.
On the device, Settings -> Security, have you enabled installation from 'unknown sources'?
If you run 'monitor' or 'monitor.exe' in a terminal, then do the install, is there any additional context surrounding the installation error that might be useful?
If you run 'adb devices', is your device listed? Yes, your device may very well return a serial id instead of a name.
What is your adb version? adb --version
Try to install the built apk manually
adb devices
adb install /path/to/your/project.apk
