[Ifeffit] Larch version up problem

[정은석]

Hello~

I used Larch 0.9.71. until now. However, I would like to update larch and I
reinstall anaconda and larch.
I installed Larch 0.9.74. as following installation guide
I didn't have any problems during the installation process. However, I
faced problems during feffit fitting.
Before, I used feffit fitting in larch 0.9.71., and then I hadn't had any
problems.

I only changed larch as new version. What am I doing?

When I run feffit fitting, I have debugs as the below:
-------------------------------------------------------------------------------------------------------------------------
  File
"c:\Users\Administrator\Desktop\RL\feffit_error_test\test-feffit.py", line
51, in <module>
    out = feffit(pars, dset)
          ^^^^^^^^^^^^^^^^^^
  File
"C:\ProgramData\anaconda3\envs\xraylarch\Lib\site-packages\larch\xafs\feffit.py",
line 645, in feffit
    ds.prepare_fit(params=params, other_hashkeys=dset_hashkeys)
  File
"C:\ProgramData\anaconda3\envs\xraylarch\Lib\site-packages\larch\xafs\feffit.py",
line 374, in prepare_fit
    self._generate_hashkey(other_hashkeys=other_hashkeys)
  File
"C:\ProgramData\anaconda3\envs\xraylarch\Lib\site-packages\larch\xafs\feffit.py",
line 291, in _generate_hashkey
    dat = [self.data.ek0, self.data.e0, self.data.rbkg]
           ^^^^^^^^^^^^^
AttributeError: 'Group' object has no attribute 'ek0'
