Tried running rf-detr locally but keep running into this: Loading pretrain weights UserWarning: The operator ‘aten::\_upsample\_bicubic2d\_aa.out’ is not currently supported on the MPS backend and will fall back to run on the CPU. This may have performance implications. Is there support with Apple silicon with RF-DETR? ---

People were talking Apple and RF-DETR on [the Discord channel](https://discord.com/channels/1159501506232451173/1354435462240141354/1383860680469254184) last month so if you don’t hear something here you might check out there too. ---

Try calling `model.optimize_for_inference()` before running inference. This should be available in the develop branch of the RF-DETR repo ---

yes i tried that but it seems like to actually instantiate the model i need to use RFDetrBase which does not have the function `optimize_for_inference()` ---
