…=True) v2.ToTensor() has emitted a UserWarning on construction since torchvision 0.15. Use the officially recommended replacement (output equivalent up to float precision). Co-Authored-By: Claude <noreply@anthropic.com>

Fix #1418
Summary
Replaces the deprecated
v2.ToTensor()inlightx2v/models/runners/wan/wan_matrix_game2_runner.pywith the officially recommendedv2.ToImage()+v2.ToDtype(torch.float32, scale=True).v2.ToTensor()has emitted aUserWarningon construction since torchvision 0.15 (first release of the v2 namespace); the warning text explicitly recommends this exact replacement:Changes
lightx2v/models/runners/wan/wan_matrix_game2_runner.py:v2.ToTensor()→v2.ToImage()+v2.ToDtype(torch.float32, scale=True)inside the existingv2.Compose.Validation
Verified with torchvision 0.26.0 (CPU): the replacement pipeline constructs cleanly under
-W error::UserWarning, and its output is identical to the old pipeline up to float precision (max abs diff ≈ 1e-7, single last-bit rounding on uint8→float32 scaling).
