Having issue for installation on RPi 4 B 4GB

hi erik

I think I found the version 2.9.0.0 here

So did you mean that after I installed the version 2.9 I can remove many dependencies in requirements.txt and make it look like:

requests==2.24.0
argcomplete==1.12.1
blobconverter==0.0.10
# --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/
# depthai==2.5.0.0.dev+568cf1c566056eac5a039ebb9a1fa74436c495b5
depthai==2.9.0.0
pytube==10.8.5

Am I correct?

Hi erik

I have successfully installed Depthai 2.9.0.0 and then
I commented out the opencv-python and opencv-contrib-python in the requirements.txt
and I ran
python3 install_requirements.py
It ran successfully.

Then I tried to install opencv-python (because the program still asks for cv2)
by running pip install opencv-python, then I got the huge error again:

Am I missing anything?

erik brilliant_! There is the wheel already ! haha thanks a lot_!

For the opencv-contrib-python I found it here
However, it does not have the same version 4.5.3.56 as for opencv-python.

If I installed the older version opencv-contrib-python, will it cause issues?(I imagine they won't be compatible which is a big issue)
Why do I still need opencv-contrib-python even after I installed opencv-python?

Once again, thanks for your help.

Cheers,

Winston

thanks erik so "that version" means the version for opencv-python, right?

And if I understood you correctly, I won't need the opencv-contrib-python right?
It would be a great relief if I didn't need to install one more hard-to-install package haha.

Thanks
Winston

Morning erik Now I understood, I can install

1. Depthai 2.9.0.0
2. opencv-python 4.4.0.46
3. opencv-conrib-python 4.4.0.46

I have checked the Github code for DepthAI and still cannot find the version 2.9.0.0. So I hope the version 2.9.0.0 of DepthAI(DAI) will be compatible with the 4.4.0.46 of both opencv-conrib-python(OCP) and opencv-python(OP).

thanks erik for clarifying the installation. So I just need to install the depthai 2.9.0.0 and this lib will contain OCP and OP.

Okay, so after I installed it and a couple of other dependencies(including setup the USB rules) and I ran:

$ python3 depthai_demo.py -cnn deeplabv3p_person

So this is the error I got. Could you please help?
Btw, my python3 is 3.7.3

Many thanks,

hi erik thanks for your timely update.
Excitingly, after I fixed a few other places, it finally works now_!

I have created a PR for this.
