Where can I find the universal layer module?

[Ta-Gu]

I checked the file model_video_caption_mplug.py but I find there is no universal layer module in the code, but I see that images are first fed into visual encoders and then fed into text encoders. Does it mean universal layer is actually text encoder?

I am glad that I found it in the text_encoder and there is a variable named uni_layer.
