ValueError: "Non-square pixels. Please resample data."

[Tiantian92]

Hello,
I meet a problem with this :
[File ~/Library/Python/3.9/lib/python/site-packages/pvextractor/utils/wcs_utils.py:21, in get_spatial_scale(wcs, assert_square)
19 np.testing.assert_almost_equal(abs(scale[0,0]), abs(scale[0,1]))
20 except AssertionError:
---> 21 raise ValueError("Non-square pixels. Please resample data.")
23 return abs(scale[0,0]) * u.Unit(wcs.wcs.cunit[0])

ValueError: Non-square pixels. Please resample data. ]
How should I resample the data?
My pixel size is 0.58 arcsecond. I am not sure if this is related with my python version.

Looking forward hearing from of you!
