bash get_pi_requirements.sh Error for Raspberry PI 4 64 bit OS beta

[hackebike]

I am installing the TensorFlow and got the error below: I am on a Raspberry PI 4 8Gb 64 bit OS beta, Linux 5.10.11-v8+ #1399 SMP PREEMPT Thu Jan 28 12:14:03 GMT 2021 aarch64 GNU/Linux. Python installed 3.7.3. Errors at the beginning and at the end:

"E: Unable to locate package libjasper-dev E: Package 'libpng12-dev' has no installation candidate"

"Could not find a version that satisfies the requirement opencv-python==3.4.6.27 (from versions: 3.4.10.37, 3.4.11.39, 3.4.11.41, 3.4.11.43, 3.4.11.45, 3.4.13.47, 4.3.0.38, 4.4.0.40, 4.4.0.42, 4.4.0.44, 4.4.0.46, 4.5.1.48) No matching distribution found for opencv-python==3.4.6.27 tflite_runtime-2.5.0-cp37-cp37m-linux_armv7l.whl is not a supported wheel on this platform."

Any suggestions on how to fix this? thx

Hmm... can you try using this command to install OpenCV? pip3 install opencv-python==3.4.13.47

Then, can you use these commands and let me know what the output is? uname -a cat /etc/os-release

[hackebike]

Alright, for now I am just going to say that you should switch to using the normal 32-bit Raspberry Pi OS. Feel free to tinker around and see if you can get it working on 64-bit! If you are able to get it working, please share how you did so :)

[hackebike]

Can't switch to 32 ! Will try to see if I can find a solution.

[hackebike]

Btw in the script needs an update for for Raspberry PI OS 64 bit beta kernel 5.10

pip3 install https://github.com/google-coral/pycoral/releases/download/v1.0.1/tflite_runtime-2.5.0-cp37-cp37m-linux_aarch64.whl

[EdjeElectronics]

Thanks! Hopefully you will be able to find 64-bit versions of all the other required packages, too.

Out of curiosity (to help me better understand the types of applications that Raspberry Pi users work on), why do you need 64 bit? The 32 bit version has access to all 8GB of RAM, but it has the limitation that a single program cannot use more than 4GB of RAM. Are you working on a program that will use more than 4GB of RAM?

[hackebike]

I got it to install OpenCV and you need to make sure that pip3 is the latest version since it needs at least v19 for the install. So basically to install on the Raspberry PI 4 64 bit OS beta, python 3.7 the script needs these updates:

pip3 install --upgrade pip
pip3 install opencv-python
pip3 install https://github.com/google-coral/pycoral/releases/download/v1.0.1/tflite_runtime-2.5.0-cp37-cp37m-linux_aarch64.whl

I am doing development and will need to use 64 bit since I will use other software too, like speech recognition and bunch of other sensors. I do not have an immediate need, so I have time to got over the pain of been on beta OS ! :)

[hackebike]

I think is working, run the various script and the only one that failed is the webcam one, since camera on the PI OS 64 bit has issues:

python3 TFLite_detection_webcam.py --modeldir=Sample_TFLite_model
Traceback (most recent call last):
  File "TFLite_detection_webcam.py", line 171, in <module>
    frame = frame1.copy()
AttributeError: 'NoneType' object has no attribute 'copy'

Btw, if I want to see the obj recognition done on the PI from a mobile application, stream done via WiFi, can I use the stream class to provide the video to a web page which is accessed from the mobile app, would it work? Currently I passed bunch of data via XML from the PI to a mobile app, would like to pass the live video obj detection too.

It didn't solve my problem , for installing tensorflow 2.2 on raspberry pi 4B , 8G . I raised this issue on ur Twitter page . Thanks

Hello guys, After updating python and opencv-python, I was able to run the Object detector. Thanks a lot Hackebike. I'm using the Raspberry Pi 4 with Raspbian 10.9 32 bit OS.

This is where I'm stuck. The problem here is that if you're using a picamera module (or in my case the Arducam 16MP), you need to use the picamera2 library to create the stream, as opencv does not yet support the libcamera module. Hopefully this will change at some point, but in the meantime, I'm trying to figure out how to adapt the video stream class code to use picamera2. picamera2 has example docs on how to use with open cv and how to stream, but not how to stream to opencv. i'm not a python dev, so if anyone has tips, that'd be appreciated.

I was able to just modify the "get_pi_requirements.sh" script to install defaults. opencv and tensorflow seem to be working for me. I have yet, though, to test generating my own model. Will update.
