Can I try to downgrade the TensorRT version on my Drive Orin, which is currently at version 8.4.12, for some specific reasons? The version which I need is 8.4.10.
Will it cause any other issues? If it is possible, what are the steps involved?

Dear @zhixin.zhou,
You can not downgrade just TensorRT alone. TensorRT is part of DRIVE OS package. You need to downgrade DRIVE OS to downgrade TensorRT.

The version which I need is 8.4.10?

But the DRIVE OS 6.0.4(The first release for DRIVE Orin) has TRT 8.4.11. May I know why you are looking for this version?

Dear SivaRamaKrishnaNV

Because our Drive OS was previously on version 6030, and our model’s engine versions are all 8.4.10. Since we still have Drive Orin devices on the 6030 version, I wanna know if it’s possible to downgrade the TensorRT version on the 6050 devices. This way, we can avoid maintaining two sets of engines. Or do we have a better alternative?

Dear @zhixin.zhou,
No. You can not downgrade TRT version alone as clarified earlier.
