Hello, I’m currently trying to enable GPU acceleration for PyTorch on my Jetson AGX Orin. System Information Item Version Device Jetson AGX Orin Developer Kit (64GB RAM) JetPack / L4T 6.1 (L4T 36.4.0) CUDA 12.6.68 cuDNN 9.3.0 TensorRT 10.3.0 Python 3.10.12 Ubuntu 22.04 OpenCV …

Hi, What error log do you get if numpy<1.0? We have another method for building PyTorch from source. Please refer to the topics below. [image] PyTorch for Jetson Announcements Below are pre-built PyTorch pip wheel installers for Jetson Nano, TX1/TX2, Xavier,…

Hi, Please try below commands to check whether issue exists pip uninstall numpy pip install "numpy<2" Thanks

Hi, thanks for the response. The issue I’m facing is that when I downgrade NumPy to <2 so that PyTorch works, my OpenCV CUDA build stops working. The reason seems to be: PyTorch wheels for JetPack 6.1 require NumPy 1.x. OpenCV with CUDA on JetPack was compiled against NumPy 2.x. So when I…

Hi @blueberrie , Generally, prebuilt packages expect a specific version of each dependency, as you saw even if it installs doesn’t mean it will be compatible. Since you have custom versions, it would be better to build PyTorch from source on your Jetson board. To do so follow the instructions descri…
