Hi @bhuvanmdev, thanks for working on this!

I must apologies for the making the issue clear when I first created it. Models which are linked through # Copied from statements should be modified together i.e. CLIP should changed and then realted models like altclip included in this change.

As there's other PRs open to add this feature to CLIP, those will take precedence over this PR. Apologies for the time that you've already spent adding it to this model.

[bhuvanmdev]

I did get to understand the architecture behind CLIP like models a bit better :), so it was'nt a waste of time.
Then in that case, should I just close this PR?
