AttributeError: 'tuple' object has no attribute 'shape'

[kkyyhh96]

When I was running the example code of the project, I met the following error:

---> 2 mgwr_bw = mgwr_selector.search() AttributeError: 'tuple' object has no attribute 'shape'

I only ran the cell [1]-[3] and then [5]-[6]. My python version is 3.8 on Ubuntu. The mgwr version is 2.1.1.

Please note that to read the data I unzipped the zip file and used the following code: prenz = gp.read_file(ps.examples.get_path('prenzlauer.shp'))

ran the example code at https://mgwr.readthedocs.io/en/latest/generated/mgwr.gwr.GWR.html#mgwr.gwr.GWR
tried #basic model calibration, which is import libpysal as ps from mgwr.gwr import GWR data = ps.io.open(ps.examples.get_path('GData_utm.csv')) coords = list(zip(data.by_col('X'), data.by_col('Y'))) y = np.array(data.by_col('PctBach')).reshape((-1,1)) rural = np.array(data.by_col('PctRural')).reshape((-1,1)) pov = np.array(data.by_col('PctPov')).reshape((-1,1)) african_amer = np.array(data.by_col('PctBlack')).reshape((-1,1)) X = np.hstack([rural, pov, african_amer]) model = GWR(coords, y, X, bw=90.000, fixed=False, kernel='bisquare')

also returned: AttributeError: 'tuple' object has no attribute 'shape'

Python3.8. Any comments or suggestions?

Hello @kkyyhh96 and @shughestr,

I locate the problem. This happened because a recent update on spreg hasn't been reflected in the mgwr. There is a current open PR #83 from @weikang9009 should fix this problem, but it hasn't been merged yet.

A temporary fix would be to pin spreg to an earlier version e.g. v.1.1.1. pip install spreg==1.1.1.

Cheers, Ziqi

You are right, rolling back version does solve the problem! Thanks.

Solved in #83

Hi Ziqi,

We are still experiencing some issues with the GWR approach/library. We wonder if you'll have time to have a quick Zoom chat with us. We have applied SVM, Ridge Regression, XGBoost on the dataset. As we are new in this field, we can really use your help and guidance.

Just FYI, I am working on a pro bono basis with some graduate students in Canadian universities on a Real Estate price trend forecast project. I currently work for a Canadian government agency.

Let me know. Thanks.

Regards, Dave Dong
