Re: [Ifeffit] Larch version up problem

4 Feb 2024

      Hello Matt

I am sorry to bother you.

I have another problem regarding ff2chi.

This problem is similar to the previous one. Could you check it?

where self.path_lists indicates the list of path, for example,
self.path_lists=[path1, path2, path3]

Hello Matt.
Thank you for your help.
I solved my problem through your comments.
Your larch code in python gives me a great opportunity to build a new
system.
Thank you again and have a great trip :)

Hi Eun-Suk,
Sorry for the trouble.  I think this should have worked with 0.9.74,
but I also know that I already changed that section of code to avoid
similar problems.   It should work to do
       python -m pip install
https://millenia.cars.aps.anl.gov/xraylarch/downloads/xraylarch-latest-py3-n...
I think this is a pretty stable version, but I still have a small list
of things I would like to improve before releasing 0.9.75.  I have not
had a lot of time in January for coding and will be traveling for the
next couple of weeks, but talking about software a lot during that
time ;).
Hope that helps, and thanks for your patience.

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

           ^^^^^^^^^^^^^
