|
||
|
|
This is the configuration class to store the configuration of a [`TvltModel`]. It is used to instantiate a TVLT
|
||
|
|
model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
|
||
|
|
defaults will yield a similar configuration to that of the TVLT
|
||
|
|
[ZinengTang/tvlt-base](https://huggingface.co/ZinengTang/tvlt-base) architecture.
|
||
|
|
|
||
|
|
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
||
|
|
documentation from [`PretrainedConfig`] for more information.
