Cant install dependencies on addon even after updating python

[Noiet]

Soo yeah, ive done every step correctly, opened up blender with privileges and tried to install the dependencies, but whenever i tried to, it always ended up bugging and leaving this message for me

Command '['C:\Program Files\Blender Foundation\Blender 2.91\2.91\python\bin\python.EXE', '-m', 'pip', 'install', 'mediapipe', '--user']' returned non-zero exit status 1.

[https://cdn.discordapp.com/attachments/869803787785736222/959992551958519848/unknown.png](And this message on the console)

I'm not sure whats happening, i tried to restart my pc, update python, run legacy versions, but none of them worked. What could be happening?

[cgtinker]

your discord app infiltrated blender? now that's something new 😄 do you have a vpn running? if so probably turn it down.

there has been an error when processing the cmd. I'm a bit wondering about the path, think there should be double slashes. besides the path and cmd seems fine. for reference, which operating system and python version are you using?

when updating python / pip, it's sometimes required to restart blender and try the installation a second time (not sure why that happens).

if that doesn't work, a workaround also can be to use the scripting editor in blender and use this short script - might it works:

import pip
pip.main(['install', 'mediapipe', '--user'])
pip.main(['install', 'opencv-python', '--user'])

[Noiet]

Nah, i dont use VPns

I'm using windows and my current version of python is 3.10.4, i tried to that restart and reinstall thing but it didnt work

How do i add that workaround? I tried to drop it in the console here and it didnt work

[cgtinker]

Bummer it doesn't run. Not really sure what's the issue - would be nice to see the logs when the python version gets searched to further investigate it.

However, when you open blender there is a tab called "scripting" (usually the last workspace). There you can click on the "new" button -in the window you can copy-paste the script. To execute it either press the play button or "alt+p"

[Noiet]

I tried running it here but i got the following message Also, downgraded python to 2.7.3, didnt work

[cgtinker]

You accidentally have added a '[' to the script. - that's why it doesn't run.

When talking about python version, preferably use python 3.7. Mediapipe doesn't support 2.7... I've successfully installed it on 3.1, 3.7, 3.9.

[Noiet]

I tried downgroading to exactly 3.7 and reinstalled, i got an error that is a bit different but still the same in a way

Also, i tried to run the workaround code again with the mistake fixed but it still didnt work

[cgtinker]

the good thing is that the wheel for setting up mediapipe was found, sadly it doesn't spin. I never had this issue so I can just guess:

You should consider upgrading via the 'python -m pip install --upgrade pip' command, so lets try that. Not sure if it makes any difference but I'd try to install the packages using the terminal:

ensure pip C:\Program Files\Blender Foundation\Blender 2.91\2.91\python\bin\python.EXE -m ensurepip upgrade pip C:\Program Files\Blender Foundation\Blender 2.91\2.91\python\bin\python.EXE -m pip install --upgrade pip install open-cv C:\Program Files\Blender Foundation\Blender 2.91\2.91\python\bin\python.EXE -m pip install opencv-python install mediapipe C:\Program Files\Blender Foundation\Blender 2.91\2.91\python\bin\python.EXE -m pip install mediapipe

In this case I'd probably also consider to clear the CMake cache. Sadly no idea about the path.. rm CMakeCache.txt

Try that before going further, there is an issue building the whl so it probably should be reported to mediapipe.

[Noiet]

I Did all of that except the last one (The Rm CMakeCache one) but it still didnt work, its giving me a similar error
