Set SDK Root/Resource Directory

Software C++

Hi folks,

I’m integrating the SDK into my toolchain, using zed_sdk.run --noexec --noprogress --nox11 --chown --target my_install_dir it was easy enough to install it to particular directory. Everything builds just fine using that, but when running my program fails complaining that it can’t download the calibration files/models/etc. to /usr/local/zed instead of using my_install_dir. /usr/local/zed doesn’t exist and would need root permission to create.

How do I change the directories it uses for the SDK during runtime? Or at least the resource directories for calibration files/optimized models? I looked all through the docs/Camera.hpp and didn’t see anything so any help would be appreciated.

Thanks!

In short, you currently can’t for AI models. This will be configurable in the future

For calibration files, you can set it in the InitParameters::optional_settings_path

Hi folks,

I wanted to see if this is supported yet, if there’s some sort of environment variable or something I can set to choose where the models get downloaded/optimized from?

You can set a custom install directory with recent versions.
To install, you use the install_path option;

bash ZED_SDK_XXX.zstd.run -- --install_path=/custom/path/zed

Then the ZED_DIR env var must be set to this value (you can put it in your bashrc for instance)
