Thanks for your great work!
In the paper, Figure 2 visualizes 2D CLIP Embeddings and i want to visualize 2D CLIP embedding on asknerf_drill_mat_block dataset, coulud you please give me some guidance?
I firstly extract CLIP features and save it as clip_clip_openai_RN50x64.npy.
Then i load clip_clip_openai_RN50x64.npy and bilinear interpolation is then used to recover the dimension from [1024, 14, 24] to [1024, 134, 239] , and the visualization is as following.

The result seem to have something wrong, so coulud you please give me some guidance to visualize 2D CLIP Embeddings?
Looking forward to your reply!
Thanks again!
