Re: [Ifeffit] Larch version up problem

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 :) 2024년 2월 4일 (일) 오전 12:59, Matt Newville 님이 작성:

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",
