Starts up okay but then changes back to CPU.

Log shows:

11:05:40:Started Object Detection (Coral) module
11:05:45:objectdetection_coral_adapter.py: Unable to load OpenCV or numpy modules. Only using PIL.
11:05:45:objectdetection_coral_adapter.py: Using Edge TPU

Tried installing numpy manually in a similar fashion to how we had to downgrade on the previous module but just get errors:

A new Coral module has been uploaded. You'll see an update button on the install modules tab on the dashboard

Hey Chris,

Many thanks Smile | :)

Unfortunately i am still getting the exact same behaviour (2.3.3)

14:44:35:Started Object Detection (Coral) module
14:44:41:objectdetection_coral_adapter.py: Unable to load OpenCV or numpy modules. Only using PIL.
14:44:41:objectdetection_coral_adapter.py: Supporting multiple Edge TPUs

Then it falls back to using CPU (TF-Lite).

Same issue when trying to run pip command once I've activated the python environment also.

Is there a way I can install 2.3.0 to confirm everything is back okay on that version?

We released Coral 2.3.4 yesterday. Does that change anything? After uninstall module, then reinstall?

Thanks,

Still the same thing:

So I disabled Blue Iris and started it up, got the "Unable to load OpenCV or numpy modules. Only using PIL." message straight away, but it still showed it was using the TPU.

Left this for 8 mins and it continued to show TPU. The minute I started Blue Iris and it sent something to be analysed (14:45) it flips it to CPU.

"Unable to load OpenCV or numpy modules. Only using PIL" is just info. Ignore.

Is there anyway I can download 2.3.0? I believe this was the last one that worked correctly, just to see everything is okay my end?

Chris Maunder3-Jul-24 6:26

3-Jul-24 6:26

There was no 2.3.0, but here's 2.3.1[^]

Remove the \bin folder in the Coral module's folder
Unzip this zip into the Coral module's folder
open a terminal in that folder, and hit ....\setup

Be patient, and it should install.

cheers

Hi Chris,

Many thanks for the reply, is the version before 2.3.1 available? 2.3.1 seemed to be when things started to go wrong.

Thanks a lot

Chris Maunder3-Jul-24 6:44

3-Jul-24 6:44

Try 2.2.2

cheers

Hi Chris,

So far so good on 2.2.2. Had to downgrade numpy from 2.0 to 1.21.6, but after that it started straight up and has stayed using TPU since.

yeah 2.2.2 was the last stable version for me Frown | :(

Matt Wilkinson 20244-Jul-24 1:03

Yep 2.2.2 has been rock solid for me since last night now

Matt Wilkinson 20243-Jul-24 19:33

Yep 2.2.2 rock solid again. Let me know if you need anything to help

At least one other person is reporting that 2.2.2[^] is working fine for them.

Just performed the downgrade to 2.2.2 under Windows. When starting the module the following failure messages are popping up. What can I do?

Unfortunately, when I downgrade the coral module, I get the message "This module cannot be installed on this system". Am I missing something?

1. I removed the bin folder -> C:\Program Files\CodeProject\AI\modules\ObjectDetectionCoral\bin
2. I copy/overwrite the content from 2.3.1 (i also try the other version below) in the \Program
Files\CodeProject\AI\modules\ObjectDetectionCoral folder.
3. then io run the setup.bat script from C:\Program Files\CodeProject\AI\setup.bat

has anyone seen where i made the mistake?

Matt Wilkinson 20248-Jul-24 9:42

8-Jul-24 9:42

Have you loaded the batch file from within the module folder? The command should be

..\..\setup.bat

...that was my the problem... thx a lot Smile | :)

but i run into the same issue as the comment (Jens_G) above.
I think I need to look further into where the problem might lie, but thanks for the help Smile | :)

The problem is after 60seconds of inactivity the script is unable to find the TPU module and is falling back on CPU detections and need to restart the module so it can continue to use TPU module
