I, too, cannot load (enable) the GANverse3D (Image2Car) Extension. I have been trying to get it to work since it was made available.
I followed the steps, as another poster mentioned/linked to in a post above, to download the .zip file and import it into the list of Extensions, but when I click to ‘enable’ it, it shows a red exclamation mark symbol in place of the enable/disable switch. It is thus not able to been seen/used within Omniverse.
Looking at the console log, it makes mention of 'ModuleNotFoundError: No module named ‘onnxruntime’…
This is on Windows 10, build 21H1, using the latest Studio Drivers with an RTX 3090 card, and an Intel Core i9 10940X CPU (X299 platform) with 64GB of RAM . The various Omniverse apps, Connectors, Launcher, etc are always updated when new versions become available.
I have re-downloaded the .zip file, and tried various other troubleshooting steps, but it’s always the same result… A red exclamation mark, and the Extension is not enabled.
Thanks in advance for any assistance.
