"cl" or "itc" loss in forward

[Markin-Wang]

Hi, thank you for your great work.

I am trying to reproduce the results and found that it seems a issue regarding the name of the contrastive learning loss.

The image-text contrastive loss is defined as "itc" in config file, while in the line below

PTUnifier/ptunifier/models/ptunifier_module.py

Line 371 in eee60eb

if "cl" in self.current_tasks:

the if statement is for loss name "cl" which seems cause the image-text contrastive loss not included and also the wrong validation score ( itc value always Nan).

Could you please help confirm the right loss name, thanks.
