tried (1,) - still same error ...
printed z and looks right, len(z) OK
(puzzling)

I don't use Numpy, so this is just a guess, plus reading one web page.
According
I created an xy pair
y = slope*x + intercept
then I added some noise to y using
numpy.random.normal - call it z
I could recover the slope, intercept from (x,y) using linregress
BUT cannot calculate the slope, intercept from (x, z)
What is puzzling is that for both pairs (x,y) and (x,z) the
