Concatenation of prefix and embedding_text in torch.cat

[Tshuning]

First of all, thank you for your valuable contribution! I am currently studying your code and have a question about a particular section. Could you please help me understand the following line of code:

embedding_cat = torch.cat((prefix_projections, embedding_text), dim=1)

I noticed that prefix_projections and embedding_text are concatenated along dim=1. I'd like to inquire about the purpose behind combining these two tensors. Is it serving as a prompt?

Once again, thank you for your patience and contribution!

Best regards
