TypeError: float() argument must be a string or a number, not 'OrdinaryKriging3D'

[CognitiveQualia]

When executing this line of code in the first example:

abund, errs = models.find_abund(wl, flux, flux_err, t_eff, log_g, met)

I am met with this issue:

TypeError: float() argument must be a string or a number, not 'OrdinaryKriging3D'

I'm using Python 3.6. What might be the problem here?

[ellawang44]

I'm not able to replicate this issue on Python 3.7.6 or Python 3.6.12.

Could you post the full error log please? Can I also get what version of PyKrige you have installed?

I am having the same issue. The full error:

Also -- it looks like your link to http://www.mso.anu.edu.au/~ellawang/ no longer works, so I was unable to run the demo with example.txt.

It looks like a call to predict_flux under breidablik.interpolate.spectra went wrong, would you happen to know the inputs you used for predict_flux to cause this? I've tried a few different inputs and I can't replicate this. Looking at your error log it should be this line of code: pred_flux = models.predict_flux(bteffs[i], g[i], 0., newabund). It would be helpful to know what bteffs[i], g[i], and newabund is.

About the link to http://www.mso.anu.edu.au/~ellawang/ this is working for me simply clicking on it. There is however, no such file called example.txt and I can't find where I reference it. Did you mean example_spec.txt perhaps?

[astahl7]

Huh - for some reason that link works for me now. Before the whole
thing would 404.

I also get the same error when running the example step 1 with
example_spec.txt:

from breidablik.interpolate.spectra import Spectra from breidablik.analysis import read pred_wl = read.get_wavelengths() models = Spectra() wl, flux, flux_err = np.loadtxt('example_spec.txt', unpack = True) abund, errs = models.find_abund(wl, flux, flux_err, 5777, 4.4, 0)

Gives

The inputs should be totally uniform with the example...

It's quite likely that you're running on an old version of the code. Did you install through pip by any chance? I think the code on pip may be old.

I've just updated the pip version of the code, which I think should fix your problems. The code version is now 0.6.5, you can check your version via pip show breidablik or in the setup.py file of the repository, depending on how you've installed the code.

I would recommend a reinstall of the package, if you're running pip: pip uninstall breidablik then pip install breidablik if you've installed through github: delete the repository, then git clone https://github.com/ellawang44/Breidablik, and follow the installation instructions again.

Do let me know if the problem persists, if that's the case then it could be package version issues.
