fastvideo.fastvideo_args

`fastvideo.fastvideo_args`#

The arguments of FastVideo Inference.

Module Contents#

Classes#

`ExecutionMode`	Enumeration for different pipeline modes.
`FastVideoArgs`
`TrainingArgs`	Training arguments. Inherits from FastVideoArgs and adds training-specific arguments. If there are any conflicts, the training arguments will take precedence.
`WorkloadType`	Enumeration for different workload types.

Functions#

`get_current_fastvideo_args`
`parse_int_list`
`prepare_fastvideo_args`	Prepare the inference arguments from the command line arguments.
`set_current_fastvideo_args`	Temporarily set the current fastvideo config. Used during model initialization. We save the current fastvideo config in a global variable, so that all modules can access it, e.g. custom ops can access the fastvideo config to determine how to dispatch.

API#

class fastvideo.fastvideo_args.ExecutionMode[source]#

Bases: str, enum.Enum

Enumeration for different pipeline modes.

Inherits from str to allow string comparison for backward compatibility.
