I am trying to use the depthai viewer with oak-d sr camera, it installs the approiopate the modules. But it throws a list of errors once creating the virtual environment. See the attached errors below:

Hi @gdeanrexroth ,
Are you on corpo network? As something is blocking the blobconverter library from downloading the model.

    erik Yes I am on a corp network. Is there a way that I can work around this? For the last month, I have been simply trying to use the depthai viewer along with simple point cloud functionality.

      @gdeanrexroth not that I'd know of, except of downloading the blob via eg. mobile data (or downloading it locally from home and transferring it to your computer). Blobs are saved locally at Path.home() / Path('.cache/blobconverter').

        erik How important is the blob or blobs? Do they grant me access to bypass the ssl errors that I am encountering?

          They are models that are required to run default viewer (to show object detection bounding box on the stream).
