Unable to pip install depthai

Syun

Dear DepthAI Experts,

Hello.

I would like to get my hands on the depthai library.

I install it with pip.

I used a new PC (windows 11) and followed the following site.

https://docs.luxonis.com/projects/api/en/latest/install/#windows-10

Here are the steps I followed

Choose Windows PowerShell (Admin) and run the following:

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

Close the PowerShell and then re-open another PowerShell (Admin) by repeating the first two steps.

Install Python and PyCharm

choco install cmake git python pycharm-community -y

thereafter

Enter the command in Windows PowerShell (Admin)

python -m pip install depthai

However, I get the following error. I do not know how to resolve the error.

Am I missing a step?

Also, is there a solution to the above error?

PS C:\Windows\system32> python -m pip install depthai

Hi Syun
Try:

python -m pip install --upgrade pip setuptools
install prebuilt wheel from https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/depthai/ (i assume you are looking for win-amd64.

Thanks,
Jaka

Syun

Thank you for answering .

I don't know how to download this pre-built wheel.

Should I download it with pip or git?

Should I put it in a specific file somewhere?

Syun

I ran this code.

pip install depthai-0.0.2.1+00ca3534d2e92af2b8e3aff9a8e5bc96b6bb1993-cp35-cp35m-win_amd64.whl

And this error occurred.

WARNING: Requirement 'depthai-0.0.2.1+00ca3534d2e92af2b8e3aff9a8e5bc96b6bb1993-cp35-cp35m-win_amd64.whl' looks like a filename, but the file does not exist

python version is 3.12.

Please tell me how to choose wheels.

jakaskerl

Hi Syun
You must download the .whl file. The you can install it using pip install [wheel file name].

Thanks,
Jaka

Syun

Hi jakaskerl

Thank you

pip install [wheel file name]in the command prompt, right?

Please tell me what wheel file name I should choose this time.

https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/depthai/

There are many wheel files in this list, so which one should I choose?

I will introduce the performance of my PC if necessary.

【OS】Windows 11 Home 64

【CPU】AMD Ryzen Z1 Extreme

Hi Syun
I think this one https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/depthai/depthai-2.24.0.0.dev0+855e0208361d60ad250bc83ae64ce7d44e23140d-cp39-cp39-win_amd64.whl

Thanks,

Syun

jakaskerl

Excuse me, I ran the code below and got an error.

pip install https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/depthai/depthai-2.24.0.0.dev0+855e0208361d60ad250bc83ae64ce7d44e23140d-cp39-cp39-win_amd64.whl

The error content looks like this:

ERROR: depthai-2.24.0.0.dev0+855e0208361d60ad250bc83ae64ce7d44e23140d-cp39-cp39-win_amd64.whl is not a supported wheel on this platform.

Do you know what caused the error?

jakaskerl

Hi Syun
Uh, sorry, I was sure you had python 3.9. We don't currently support python 3.12 (that said I, it should be supported soon). That's why you can't install it in the first place. I suggest using python 3.11.

If you get similar error, then this wheel (for 3.11) should install just fine.

Sorry for the confusion.

EDIT: We added python3.12 to supported versions. It should now work. The wheel for the 3.12 version will be available in the artifactory shortly.

Thanks,
Jaka

Syun

jakaskerl

Thank you, it worked fine with python 3.11.

userOfCamera

I had the same problem as @Syun on Windows 11/Python 3.12. Fixed by downgrading to Python 3.11, 3.12 not supported for me @jakaskerl

jakaskerl

Hi @userOfCamera
What do you mean by "not supported for me"? Does this wheel not work?

Thanks,
Jaka

userOfCamera

jakaskerl The pip download did not work, I had the exact same error as OP (it worked fine on Python 3.11)

jakaskerl

Hi userOfCamera
It's not yet mainlined so main branch will still pull from the same url. Either switch to luxonis/depthai-pythontree/update_python_312 and run install_requirements.py, or download the wheel and install it manually.

Thanks,
Jaka
