RuntimeError: solve_cuda: U(4,4) is zero, singular U.

Hi, Just trying to test this, but I get the following issue:

The last line changes. For example it could also be:

RuntimeError: solve_cuda: U(29,29) is zero, singular U.

@nerdyrodent same issue here, did you manage to solve it?

Same issue.... @nerdyrodent @alejandrosatis did you find a way to fix it?

In my case:

  File "C:\Users\corra\myproject\venv\DST\main.py", line 102, in <module>
    output = DST(initial_im, content_im_orig, style_im_orig, extractor,
