*** ValueError: operands could not be broadcast together with shapes (2888,) (216,)

[iancharest]

f = fracridge(np.concatenate(desw),  np.concatenate(data2), opt['frac'])
np.concatenate(desw).shape
(648, 216)
np.concatenate(data2).shape
(648, 2888)

The error perhaps happens in here?

fracridge/fracridge/fracridge.py

Line 51 in 46c3090

if X.shape[0] > X.shape[1]:

The next three lines result in ynew being of shape (2888,)

uu, ss, v_t = svd(X.T @ X)
selt = np.sqrt(ss)
ynew = np.diag(1./selt) @ v_t @ (X.T @ y)

this then breaks the line:

ols_coef = (ynew.T / selt).T

df4f363 ?

I believe this is a duplicate of #20. It’s fixed on master through #21, but this is a good reminder that I need to push a new release to pypi.

OK. Just released version 1.3.2, so another pip install -U fracridge should set you straight.

Thanks for the poke!
