Build failed when installing from PyPi on Ubuntu Server 20.04.2 LTS

[andrebrehme]

I am trying to install the depthai library from PyPi on a Raspberry Pi 4 B (4GB version) running Ubuntu Server 20.04.2 LTS. I followed the installation instructions from the documentation but am getting this error:

ERROR: Could not build wheels for depthai which use PEP 517 and cannot be installed directly

I am using:

• Python 3.8.5
• Pip 21.0.1
• setuptools 54.1.1
• wheel 0.36.2

inside of a virtualenv.

Installation worked fine on my Laptop (Ubuntu 20.04.2 LTS, similar environment). Does this relate to the Raspberry Architecture?

Full error message:

ERROR: Failed building wheel for depthai
Failed to build depthai
ERROR: Could not build wheels for depthai which use PEP 517 and cannot be installed directly

[alex-luxonis]

Installing the library attempts to build it from source, as we don't have yet prebuilt binaries for ARM 64-bit (aarch64 here).

Looks like it fails because libusb is not found. Could you try installing it with:

sudo apt install libusb-1.0-0-dev

It's a depthai-core dependency: https://github.com/luxonis/depthai-core#dependencies

[andrebrehme]

Thanks a lot, this helped and the library built without any errors!

I actually had a look at the depthai-core dependencies but it seems that I didn't checked for libusb.
