Common Pitfalls
1
Neglecting to check Tensor Core utilization can lead to suboptimal performance.
Many models may not effectively utilize Tensor Cores, which are crucial for maximizing performance on NVIDIA GPUs. Always review this metric during profiling.
2
Failing to set the correct layout and precision when exporting to PyTorch can cause compatibility issues.
Ensure that you specify the NHWC layout and FP16 precision to leverage the full capabilities of your model in PyTorch.
