To someone who knows it,
I am currently testing my CSEM code based on FE method, and also testing EMG3D for comparison. Since I was not that expertise with Python, I encountered following problem when testing Example 4(Adjoint-state vs. FD gradient) from the Gallery:

AttributeError                            Traceback (most recent call last)
<ipython-input-7-9618786023c8> in <module>()
      5     frequencies=1.0,
      6     noise_floor=1e-15,
----> 7     relative_error=0.05,
      8 )

D:\Program Files (x86)\anaconda\lib\site-packages\emg3d\surveys.py in __init__(self, sources, receivers, frequencies, data, **kwargs)
    131 
    132         # Get the optional keywords related to standard deviation.
--> 133         self.noise_floor = kwargs.pop('noise_floor', None)
    134         self.relative_error = kwargs.pop('relative_error', None)
    135

    569     def noise_floor(self, noise_floor):
    570         """Update noise floor."""
--> 571         self._set_nf_re('noise_floor', noise_floor)

    680 
--> 681         self._data.attrs[name] = value
    682 
    683     @property

AttributeError: 'Survey' object has no attribute '_data'

I don't know if it is a bug. I would appericiate if someone could help me with it!

Hm, hard to say if it is a bug or another problem without any further information.

Do you have xarray installed?

Could you install scooby (pip install scooby or conda install -c conda-forge scooby) and post here the output of emg3d.Report()?
