SDK Core ML Utils API
Miscellaneous operations in Pytorch
-
metavision_core_ml.utils.torch_ops.cuda_tick() Measures time for torch operations on gpu.
-
metavision_core_ml.utils.torch_ops.cuda_time(func) Decorator for Pytorch ops on gpu.
- Parameters
func – method to time

- Parameters
flow – (B,2,H,W) tensor
- Returns
(B,3,H,W) tensor
- Return type
rgb
Tools common to training main functions.
