Some questions about the test code #21

Closed Eldo-rado closed 1 year ago

Eldo-rado commented 1 year ago

👋Hi! Thanks for your code, and I have a question to confirm. When I run "As simple as using CLIP" in Readme, I try to output the values in the inputs, but I find that the values in the 'pixel_values' matrix are exactly the same (as shown in Figure 1), I wonder if this is normal? What causes this ?

Hi, are all values the same or just many -2.0976 ? This may be caused by the normalization where 0 are transformed to this value.

Thank you for your timely reply, which has completely solved my question. It just many -2.0976, not all values. I didn't consider the same pixel of background and the effect of normalization. Thanks again
