Linear Algebra Error thrown in earlier numpy versions when running orientation fixed_nrel() function.

[kperrynrel]

Following error is thrown when running fixed_nrel() function on a azimuth/tilt estimation pipeline:

raise LinAlgError("SVD did not converge in Linear Least Squares")

LinAlgError: SVD did not converge in Linear Least Squares

This occurred when running numpy=1.19.1. Updated to numpy 1.19.5 and issue was resolved. Need to update minimum numpy installation.

@kperrynrel which version of scipy was used when the error was reported?

[cwhanse]

Ah, nvm I see the issue. This helper function uses np.polyfit which is the old numpy API, not yet deprecated AFAIK but less well-mannered than its replaced np.polynomial. We should bring the helper function up to the newer API; transition guide here.

[kperrynrel]

I can do that @cwhanse, will cut a PR making an update on that function.

Closed by #120?

@kanderso-nrel correct. Closing this--thanks for tracking housekeeping on this!
