[BUG] Dependency installation issues about depthai

[brmarkus]

Others seems to have the same finding, like under "https://discuss.luxonis.com/d/1999-debian-bookworm-oak-1".

[camchaney]

Awesome, thanks. I followed this but got another error:

error: externally-managed-environment

This environment is externally managed

To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.

If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.

Package libtbb2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  libtbbmalloc2:armhf libtbbmalloc2

I am reporting the bug as directed by the script.

[brmarkus]

Did you try one of the notes mentioned above in this thread?

[LaudixGit]

Nope. This script is failing as-is and I reported it as such.
(so the next person looking will know the script has not been repaired yet)

I have the same issue. Have you resolved it?

error: externally-managed-environment

I believe I have a solution for this issue. The problem arises when pip is told to upgrade itself at the end of the installation of the dependencies. If pip was installed as an OS package (which seems to be the case at least with default Python installations on Debian), it will throw the error because it's not supposed to install/manage packages system-wide. Since we just want it to upgrade itself (and not install anything), I just added an alternative command for doing so using apt-get in environments that are externally managed (in the "non-external" ones it will run the original command).

@camchaney @jnpm would you mind testing the updated script? Just download the file and run it locally (bash install_dependencies.sh). It works nicely for me, but it would be good to get a confirmation to avoid the "works on my machine" effect :)

For reference: this behavior was implemented in Python 3.10.

[katerina-stemberova]

The newest version of the script should also fix the issue with installation of the "libtbb2" package.

@camchaney @LaudixGit feel free to test (download the file and run it locally - bash install_dependencies.sh)
