AMI name: Deep Learning OSS Nvidia Driver AMI GPU PyTorch 2.7 (Ubuntu 22.04) 20250602

Added

  • Initial release of Deep Learning AMI GPU PyTorch 2.7 (Ubuntu 22.04) series. Including a Python virtual environment pytorch (source /opt/pytorch/bin/activate) complimented with NVIDIA Driver R570, CUDA=12.8, cuDNN=9.10, PyTorch NCCL=2.26.5, and EFA=1.40.0.

Known Issues

  • "With compute capability sm10.0 (Blackwell-architecture) GPUs, the FP8 datatype with scaled dot-product attention contains a deadlock that causes the kernel to hang under some circumstances, such as when the problem size is large or the GPU is running multiple kernels simultaneously. A fix is planned for a future release." [cuDNN 9.10.0 release notes]

    • For users seeking to run P6-B200 instances with FP8 data and scaled dot-product attention, please consider installing flash attention manually.
